Why does neutral silicone glass glue crack

I make glue for the following reasons:

1: The water resistance of glass glue is not good. It is possible that it will be poured by rain when it is not dry, of course, the possibility of glue quality problems is also very large, it is recommended to squeeze out a little and put it indoors to see the curing situation.

2: If it is acidic glue, it is vinegar smell, I don't know if you use it on that occasion, the cracking is mainly the use of inferior glue, now in order to reduce costs, some black-hearted manufacturers choose ** silica gel as raw materials, or some in order to reduce the viscosity of the system using low-cost diluent white oil, curing shrinkage is relatively large, resulting in poor performance of the rubber body.

3: In addition, the cracking may be due to the hardness of the glue used is too large, and the adhesion is not very good. Or it is caused by a large difference in weather temperature.

Specific identification methods: the difference between good and bad glass glue:

1. Judging by the speed of glass glue drying, the poor ones dry slowly, and the good ones can dry thoroughly in about 12 hours.

2. Whether the glass is cracked after drying, the poor glass glue is easy to crack, and the good one is very tough.

3. The glass glue does not change color, some glass glue is easy to change color and shrink, and the effect can only be seen after a period of use, and inferior glass glue can be found in public facilities.

4. The smell of glass glue, the smell of good glass glue is very light, and the bad smell is heavy and not easy to volatile.

Scope of use of glass glue: glass installation, bathroom cabinets, faucets, basins, toilets, sealing balcony doors and windows, cabinets, mosaics and other glass products and ceramic products, as well as waterproof sealing treatment.

Glass glue type: neutral for ceramics, metals, mirrors, glass, light odor, no corrosion; Acidic is used in wood and glass (except mirrors), the smell is sour, the adhesion is strong, and there is a certain corrosion.

There is too much solvent, and after the colloid is cured, the volatiles volatilize and cause cracking.

1. Neutral silicone glass glue is the easiest to clean when it is not cured, whether it is stuck to clothes, bodies, or utensils; Some only need to add some water to rub and gently wipe with a rag, which can be easily removed, and this kind of cleaning without curing is the easiest.

2. If you accidentally get glass glue on the smooth items such as glass, you can use a knife or a blade to gently scrape it off; It should be noted that this is a bit of a manual test, otherwise it is easy to scratch your own glass.

3. The characteristics of different glass glues are also different. For example, acid glass glue and neutral glass glue contain different chemicals; It is necessary not to use the same removal method, otherwise it is easy to cause unexpected consequences.

4. You can try to use banana water to remove it, because there is a main ingredient in banana water is "butyl acetate", and butyl acetate has a "banana fragrance", which is derived from the name banana water; Pure banana water is slightly soluble in water and can effectively dissolve in various organic solvents.

5. Use nail polish remover. The usage is also the same as alcohol acetone, and the effect is also very good. Nail polish remover does not require quality, good or average, as long as it can wash off the nail polish.

After all, nail polish itself is similar to glass glue, and it is also a type that is not easy to clean after being a solid state with high viscosity.

It can be washed off with water.

Specific removal methods:

1. Use a paper towel as the first wipe;

2. Wipe it a second time with a fabric cloth. (Don't use easy sticky hair) 3, carefully rub with talcum powder or clean silt (fine powder can adhere to a very thin layer of glue) 4, and finally rinse with water to be clean.

The removal of glass glue from porcelain and glass should distinguish between edible and non-edible utensils. The best thing to do is to physically clear it. With steel wool balls, knives and water sandpaper.

Thick and many places are scraped with a knife, then rubbed with steel wool balls, and finally sanded with water sandpaper. Note that the utensils that are afraid of marking the road should be careful, so as not to fall off the glass glue and lose the ornamental meaning. For the removal of universal glue stains, the clothes are stained with universal glue stains, which can be dropped on the glue stains with acetone or banana water, and should be brushed repeatedly with a brush, and then rinsed with water after the glue stains become soft and removed from the fabric.

If it doesn't work once, you can brush it several times repeatedly and finally wash it. Do not use this method for fabrics containing acetate to avoid damaging the fabric of the garment.

When decorating, I accidentally got the silicone glass glue on the cotton pants, the best way is to find a nail polish remover and apply it slowly to dissolve the glue But be careful to fade, it is more common and safer to use wind oil.

Furui Carbon Black] specializes in the production of pigment carbon black for silicone glass glue).

Self-adhesive removal method.

According to the principle of polymer chemical isomorphism, the method of removing self-adhesive is nothing more than dissolution and anti-sticking.

One dissolution method is to dilute the base material or tackifier of the self-adhesive with an appropriate solvent to make it easy to separate from the object to be adhered to.

Another anti-stick method is to use the properties of self-adhesive components that are abusive to certain chemical agents to prevent self-adhesive re-bonding.

Just scrape it off with a putty knife, if it's self-adhesive, you can use a lighter or hair dryer to blow it for a while, and it will fall off as soon as it's hot. Hope it helps.

1. When the glass glue is not cured, whether it is sticking to the human body, utensils or clothing, it can be easily removed by washing with water, so the uncured glass glue is the easiest to clean.

2. Then there is the glass glue that has been cured, which is extremely difficult to remove. If the cured glass body is attached to glass, ceramics, metals and other items, you can consider scrubbing with solvents such as xylene and acetone (if you don't know these two substances, you can consider banana water, because banana water contains these two substances), if there is less curing glue on the glass and other items, you can also consider scraping off with a scraper. If you attach it to the kimono, you can consider using a brush to look at it, and if it doesn't work, you should consider banana water.

3. There is also a situation that the glass glue is glued to the hand and cured, in this case, there is no need to worry, the treatment is very simple. After the glass glue is cured, it is not sticky to the hand, so it can be removed by rubbing both hands together a few times.

Hello No reaction Acid silicone glass adhesive will corrode or can not bond copper, brass (and other copper-containing alloys), magnesium, zinc, electroplated metal (and other zinc-containing alloys), and it is recommended that bricks and stones made of articles and carbonized Sibi iron body matrix do not use acid glass glue, in methyl isobutacrylate (plexiglas), polycarbonate, polypropylene, polyethylene and Teflon (Teflon, PTFE) made of materials will not be able to obtain a good bonding effect and good compatibility. Connections that move more than 25% of the width of the seam are also not suitable for acid glass glue, and it is best not to use ordinary acid glass glue (except acid structural glue) on structural glass, and acid glass glue should not be used in places with abrasion and substantial drawbacks. The surface temperature of the substrate of silicone acid glue is more than 40, and it is not suitable for construction.

It depends on where the glass glue goes.

If the glass glue sticks to the clothes, you can use a brush to brush it first, if there is still glass glue, you may as well try to use banana water; If the glass glue sticks to your hands, you can wipe off the large pieces with paper first, then add a little water with alkaline noodles or washing powder, rub them repeatedly and wash them well;

If the glass glue is glued to the glass, first look at the area of the glass glue, it is very large, you can use a putty knife to scrape carefully, but it is best to sharpen it before using it, if the area is small, you can scrape it gently with scissors, and scrape it with a useless credit card can also play the same role. If you are worried about scratching the glass, you can use banana water first, gently rub it many times, wait for the edge to melt off, and then scrape. If there will be a layer of grease on the glass after scraping, it will be wiped with a cotton cloth dipped in gasoline or rosin perfume;

If the glass is glued to the porcelain plate brick, you can use a knife or scissors to gently scrape; If it is a wooden floor, it will be troublesome, you need to soak the sponge in boiling water until it is hot, shake the water slightly dry, wipe it several times, and the glass glue will be wiped off.

There are a lot of decoration materials, when decorating their own houses, we will choose the decoration materials we need, glass glue is an indispensable one when choosing, because we don't know how to construct this material, so we knowSilicone glass glue1. Silicone glass glue is a product that has been tested and supervised by the Ministry of Environmental Protection of the People's Republic of China, and is a recognized brand of glass glue. Rifeng products are not only qualified quality guarantee, the production, use and processing of the product can meet the requirements of environmental protection, so it is non-toxic compared to similar products, and at the same time can save resources and other environments.

2. Silicone glass glue has a lot, first of all, this product has the characteristics of high efficiency, fast drying and durability; Secondly, Rifeng glass adhesive also has good bonding and sealing, superior performance and stability, which can be used in extreme high and low temperatures from -50 to +250 or unstable environments such as ultraviolet rays, ozone, rain, hail, etc., and can still maintain good elasticity and adhesive sealing.

3. Silicone glass glue has good compatibility with metal, plastic steel, glass, concrete and marble, etc., and pays more attention to green environmental protection in material selection, using imported silica gel raw materials, which does not affect human health.

How to use silicone glass glue.

1. Use: One-component silicone glass glue can be used immediately, it is easy to beat it out of the plastic bottle with a glue gun, and its surface can be trimmed with a spatula or wood chip.

2. Sticking time: The curing process of silicone glue is developed from the surface inward, and the drying time and curing time of silicone with different characteristics are different, so if you want to repair the surface of the table, you must carry out before the surface drying of the glass glue (acid glue, neutral transparent glue should generally be within 5-10 minutes, and neutral variegated glue should generally be within 30 minutes). If you are using color separation paper to cover a certain area, after gluing, be sure to remove it before the skin is formed.

3. Curing time: The curing time of glass glue increases with the increase of bonding thickness, for example, 12mm thick acid glass glue may take 3-4 days to solidify, but within about 24 hours, the outer layer of 3mm has been cured. When bonded to glass, metal, or most wood, it has 20 lb-inches of peel strength after 72 hours at room temperature.

4. Bonding: Completely wipe the metal and plastic surfaces to remove oil stains, and then in addition to the plastic first rinsed with acetone to rinse all the surface, the rubber surface should be polished with sand paper, and then wiped with acetone. When using acetone, please observe the precautions for using this solvent.

5. Sealing: When silicone glass glue is used for sealing occasions, it is also carried out in accordance with the above steps, and the glass glue is squeezed into the joint surface or gap to make the glass glue fully in contact with the surface.

6. Cleaning: The glass glue can be wiped off with a cloth strip or paper towel before curing, and after curing, it must be scraped off with a scraper or scrubbed with a solvent such as xylene and acetone.

Glass glue is now inseparable from many families, in the choice of everyone needs to know how to use correctly, the above is for you to introduce how to silicone glass glue and how to use it is over here.

1. Structural adhesive is a kind of glass glue, which acts on the bonding of the parts that bear the structural force. If you need to bond the ceiling paint glass finish, you must consider the corrosiveness of the glue to the paint, if you want to withstand the structural force, you must use structural adhesive;

2. Glass glue is mainly used for some products with low requirements such as water discharge and sealing;

3. Dealcoholized silicone glass glue is neutral glass glue. Neutral glass adhesive basically does not corrode the bonding substrate; There is no pungent sour smell before the colloid dries. 995 structural adhesive belongs to neutral glass adhesive.

Neutral glass adhesive with adhesive to structural properties. It is not the best performance grade among structural adhesives, and it is recommended to do only small structural bonding.

Shanghai Xuanwei: There is no difference, many small brands imitate Dow Corning and call it 995
