How to deal with the water vapor and odor emitted by the instant glue?

Sidestep the question! Don't look at what questions are asked.

1. Control the amount of glue according to the different adhesive surfaces, and it is recommended to control it by the machine if conditions permit;

2. Strengthen ventilation, which can assist the fan and reduce whitening;

3. Prepare for the use of instant adhesive, and do a good job of surface treatment on the adhesive surface;

4. Cyanoacrylate accelerator can be used to accelerate curing;

5. The easiest way: use Kane KY low-odor low-whitening cyanoacrylate (4403 cyanoacrylate, 4460 instant adhesive), which is not easy to volatile, so the possibility of whitening is relatively small.

The main ingredient of instant adhesive is -cyanoacrylate adhesive, which is a one-component, clear, ambient fast-curing adhesive. Also known as instant adhesive, quick-drying glue.

Instant glue is easy to white, white fog, especially black plastic bonding, very affect the appearance of the product, like this kind of problem instant glue is very common, because instant glue is through the moisture in the air to produce a curing reflection, if the air is not circulated, the white mist in the curing reaction is not easy to disperse, it gathers around the adhesive surface.

Solution: First, control the amount of glue, try not to beat the glue too much, and the glue should not flow out, so that the whitening can not be seen on the bonding surface, which is both beautiful and reduces the amount to reduce the cost.

Second, choose non-albino instant adhesive, such as CA-60H glue.

Third, use a quick-drying adhesive accelerator to speed up the glue reaction and avoid white fog.

Fourth, increase ventilation in the operation workshop, and after completing the bonding, reseal the packaging as much as possible for more than 24 hours.

The reasons for the whitishing of instant adhesive are: 1. The air humidity is too high, about 60% is the most suitable, 2. There is water vapor and sweat on the adhesive surface. 3. No ventilation within 24 hours after gluing.

It is recommended to wear disposable PE gloves to operate, keep the adhesive surface clean and dry, put the product in a ventilated environment after gluing, and then pack it after 24 hours, or directly use it with HY-252 treatment agent. You can also directly use HY-306 non-whitish instant adhesive or other slow-drying glue, and there will be no whitening phenomenon.

When the cyanoacrylate molecule in the glue partially volatilizes and reacts with the surrounding water and falls, the white powdery residue left behind is whitening or frosting. There are a number of ways to avoid abrasion of albino limbs, such as ensuring adequate air movement in the assembly area, using less adhesive, or speeding up curing.

During use, air convection, ventilation, and good glue volume are operated.

Tips for using instant glue:

1. First, clean the surface of the sticky, dry and grease-free.

2. Glue is applied to the surface of the object, quickly bonded, and can be cured in about 30 seconds. Do not move during the glue pressing and curing process to avoid poor bonding or degumming. If it is bonded with silica gel, it is necessary to cooperate with the company's MW770 silica gel treatment agent, and then treat the surface of the silica gel to be bonded before bonding.

Instant glue. Precautions for the use of instant glue:

1.The best bonding effect is that the glue forms a thin film on the surface of the object, and the amount used should not be too much.

2.Store in a dry and cool place, away from heat and open flames.

3.The workplace is fireproof and ventilated to prevent long-term inhalation or long-term exposure. Please use safety gloves and protective glasses, if the glue is glued**, please wash it thoroughly with soap, and if it gets into your eyes, please wash it with water and seek medical attention quickly.

Instant glue, also known as quick-drying glue, can quickly bond products, one-component, no mixing, can be cured at room temperature, time-saving and simple operation; So now it has been widely used in the market. However, no matter which instant adhesive on the market, there will be whitening, so next, Osborne will share with you several tips for using instant adhesive to reduce instant adhesive whitening:

1. Use low-odor and low-whitening products, such as A460, etc. These products are formulated to help reduce bleaching.

2. Strengthen indoor ventilation or use a blower to cross-supply air, so that volatiles will not settle on the adhesive assembly.

3. Reduce humidity. A good way to keep humidity at a constant value is to use a dehumidifier. Recommended humidity: 40%-50%.

4. When applying the operation, use a small amount of adhesive or use a catalyst (7452 accelerator).

Cleanup Job: The cleanup job depends on the condition of the bonding subbase. In the vast majority of cases, cleaning solvents or acetone can be used to remove bleaching.

AOSBORNE's range of cyanoacrylates is suitable for fast bonding of most materials, such as: metal, rubber, plastic, glass, leather, wood, ceramics, etc.

Just pull it off, the current glue is not so strong, as soon as you pull it down, the hand skin is intact, it is stained with some glue, no special washing, and it will fall off in a day.

Scraped with a knife.

Remember to tap. No more scratching the skin.

First, the meaning is different:

Fastener fastener is a general, low-viscosity, fast-curing compound with a maximum operating temperature of 350 °C.

The glue is mainly ethyl cyanoacrylate, with the addition of tackifiers, stabilizers, toughening agents, polymerization inhibitors, etc., and the one-component synthesized by advanced production technology is instantly cured and sticky, which can stick to most of the substances of various materials.

Second, the use is different:

Glue, which is designed to bond mated cylindrical surfaces such as bushings, bearings, axles, pulleys, and shafts, racks, and also increases the strength of the press-fit. Type 601 fastener fastener will cure completely in 1-6 hours, which is determined by its structure and cleanliness, but with the help of base agent, or by heating the temperature to 250 degrees and maintaining it for 10-20 minutes, the curing can be accelerated.

Glue is used for porous and absorbent materials, used in steel, non-ferrous metals, rubber, leather, plastics, ceramics, wood, non-metallic ceramics, and its surface needs to be specially treated before it can be bonded. It is widely used in electrical appliances, instruments, machinery, electronics, optical instruments, medical, light industry and civil industries.

601 one-component, anaerobic retaining compound cures rapidly between two mating metal surfaces when isolated from air. Typical uses: used for bonding cylindrical fittings, especially for occasions requiring low viscosity; 502 glue is a one-component instantaneous curing adhesive synthesized by advanced production technology, mainly ethyl cyanoacrylate, tackifier, stabilizer, toughening agent, polymerization inhibitor, etc.
