Is water based metal anticorrosive coating good?

Water-based metal anticorrosive coatings are inferior to solvent-based coatings in terms of water resistance, hardness and adhesion. If it is a two-component baking paint water-based coating, the construction conditions are harsh, which is not conducive to the construction of outdoor environments. Some water-based anticorrosive coatings such as Xunxin NC550 can achieve high hardness and hydrophobicity, the hardness can reach a maximum of 4h, and the maximum service temperature can exceed 400.

The minimum baking temperature requirement is 60 °C, which is lower than 140 baking temperatures.

Therefore, in general, water-based metal anticorrosive coatings are getting closer and closer to or surpassing solvent-based coatings in performance. Hope.

Summary. Hello, water-based metallic paint, also known as water-based anti-rust paint, is an environmentally friendly water-based industrial paint. The formulation of water-based metallic paints is more complex, requiring the use of acrylics, water-based metallic glitter powders, silicone oils and other materials.

During the construction of water-based metal paint, it should be evenly brushed several times in one direction, and then add water and overcoat according to the situation, and the overcoating time interval is 2 3 hours, which shall be subject to drying. Next, let's take a look at the water-based antirust paint formula and construction process.

Formaldehyde exceeds the standard?

Hello, water-based metallic paint, also known as water-based anti-rust paint, is an environmentally friendly water-based industrial paint. The formula of water-based metallic paint is more complex, requiring the use of materials such as propionoate, water-based metal glitter powder, and silicone oil. During the construction of water-based metallic paint, it should be evenly brushed several times in one direction, and then added water and overcoat according to the infiltration situation, and the recoating time interval is 2 3 hours, which shall be subject to drying.

Is it okay to brush drywall furniture?

Hello, the formaldehyde content of water-based metal paint is very low and does not exceed the standard.

Hello, water-based metallic paint is not recommended to brush drywall furniture.

What kind of paint is painted for gypsum board furniture? Can it be brushed directly on plasterboard? Still is...??

Hello, gypsum board furniture can be brushed with latex paint finished paint, and the ash should be scraped twice before brushing latex paint.

1. First use caulking plaster to smooth the seams and nail holes (try to smooth them as much as possible, don't leave too large trowel or scraper marks, otherwise it is not conducive to the treatment of Dabai Na Eye later), and after drying, use paper tape or grid to paste along the seams (the paper round smile tape is pasted with diluted white latex). 2. Scrape the white, dry and sandpaper. 3. Brush latex paint.

If the gypsum board is fixed with self-tapping nails, the specification point is to nail the holes with anti-rust paint. The reason is that the self-tapping nail is in the process, because the stressed bit has damaged the anti-rust layer at the cross nail hole to varying degrees. In case of moisture, the part is first rusted.

But the moisture of the caulking plaster will not cause back-embroidery.

Anti-corrosion coatings, which are usually divided into two categories: ordinary anti-corrosion coatings and heavy-duty anti-corrosion coatings. Ordinary anti-rust coating is to resist corrosion to metals and other metals under ordinary circumstances, and can prolong the service life of non-ferrous metals; Heavy anti-corrosion coating is a traditional anti-corrosion coating that can be used in quite harsh environments, and it has a longer service life than traditional anti-corrosion coatings.

According to the shape of the product, it can be divided into liquid coating, powder coating and high solid coating.

According to the dispersion of the coating: soluble coating; Water-soluble paints (emulsion-type paints, water-soluble paints).

According to different applications, it can be divided into architectural coatings, canned coatings, automotive coatings, aircraft coatings, home appliance coatings, bridge coatings, plastic coatings, paper coatings, ship coatings, wind power coatings, nuclear power coatings, pipeline coatings, steel structure coatings, rubber coatings, aviation coatings, etc.

According to their properties, they can be divided into: anti-corrosion coatings, anti-rust coatings, insulating coatings, high-temperature coatings, aging coatings, acid and alkali coatings, and chemical-resistant medium coatings.

According to the presence or absence of colored paint, it can be divided into: varnish, color paint.

According to its construction technology, it can be divided into: sealing paint, putty, primer, secondary primer, topcoat, and overshadow paint.

According to its construction process, it can be divided into: brushing, spraying, roller coating, dipping coating, electrophoresis, etc.

According to the use, it can be divided into non-stick coatings, Teflon coatings, decorative coatings, anti-corrosion coatings, conductive coatings, anti-rust coatings, high-temperature resistant coatings, temperature indication coatings, heat insulation coatings, fireproof coatings, waterproof coatings, etc.

Home coatings mainly include interior wall paint, exterior wall paint, wood paint, metal paint, floor paint, etc.

According to the nature of the paint film, it can be divided into: anticorrosive paint, insulating paint, conductive paint, and heat-resistant paint.

According to the film-forming materials, it is divided into: natural resin paint, phenolic paint, alkyd paint, amino paint, nitro paint, epoxy paint, chlorinated rubber paint, acrylic paint, polyurethane paint, silicone resin paint, fluorocarbon resin paint, polysiloxane paint, vinyl paint.

According to the different uses, it can be divided into: metallic paint, natural paint, transparent paint, transparent paint, etc.

One reason for applying paint in decoration is to bend and punch for aesthetics, and the other reason is to protect the wall. Now that technology is progressing, the application of coatings is becoming more and more extensive, and it has a new role, which is anti-corrosion. A lot of people are rightAnticorrosive coatingsI don't know very well, what is an anticorrosive coating?

Now we will briefly introduce the relevant knowledge of anticorrosive coatings.

Now the most indispensable thing in the home is metal, doors, windows, railings, etc. will use metal, furniture and household appliances will also use metal, metal materials are most worried about being corroded, so we will use anti-corrosion coatings.

Introduction to anticorrosive coatings.

1. For the purchase of anticorrosive paint, the most realistic problem is to take into account the quality of paint. We can't buy things cheaply and ignore the quality of the product. On the other hand, we can't insist that the more expensive the product, the better.

So, in this regard, we have to be cautious.

2. Inferior latex paint not only affects the construction quality, but also endangers human health due to the substandard chemical raw materials contained in it, so you should try to buy it in a specialty store or a special dealer store. When purchasing, it is necessary to carefully inspect the packaging, appearance and internal quality of the product.

3. The construction method should be considered. Including the surface treatment of the substrate; The way of coating anticorrosive paint, whether it is airless spraying, air spraying, brush coating or roller coating: the drying method of the paint after coating is also taken into account.

4. Cathodic protection. The electrode potential of the paint film is lower than that of the base metal. In corrosive batteries, it is "sacrificed" as an anode, so that the buried metal (cathode) is protected.

5. The appropriate coating varieties should be selected according to the actual conditions of the construction site. If the site construction with poor ventilation conditions is poor, solvent-free or high-solids or water-based anticorrosive coatings should be used. In sites where baking and drying are not available, only self-drying paints can be used.

The above is the introduction of anticorrosive coatings, with the development of Huru society, anticorrosive coatings are more and more widely used in places, I hope that finishing things can give you some help.
