What is the difference between epoxy powder coating and epoxy paint coating

As a high-performance, high-value-added adhesive, epoxy resin adhesive is highly valued by the industry, but at the same time, counterfeit and shoddy products are often patronized. Therefore, we can identify it by the following chemical methods. Method 1:

The sample is dissolved in sulfuric acid, and then concentrated nitric acid is added, and a large amount of sodium hydroxide solution is poured into it. The second type: drop 5 drops of concentrated nitric acid on the resin adhesive film, move the reactant into the test tube after a few minutes, add 6ml of acetone and then add potassium hydroxide ethanol solution to make it alkaline, if it turns from red to purple, it indicates that it contains epoxy resin glue containing bisphenol A type, this method is also intuitive; Method 3:

Take the adhesive film or glue solution, p-phenylenediamine and 8ml of sample water, boil for 8min, if it is epoxy resin, the solution is peach....

Epoxy powder coating is a powder sprayed by a spray gun after heating and hot melting, which is water-soluble; Generally, epoxy paints are applied with brushes or rollers and are oil-based.

Powder coating is a type containing 100

Solid, a coating that is coated in powder form to form a film, and it uses air as the dispersion medium. Epoxy powder coating is a kind of thermosetting powder coating with corrosion resistance and toughness, which is the earliest application and rapid development, and is composed of epoxy resin, pigment filler, additives and curing agent. The preparation of epoxy powder coating is the only method for the production of thermosetting powder coating in the international market, that is, melt mix extrusion method - mixing, melt mix extrusion, fine grinding.

Epoxy resin requirements for epoxy powder coating: the epoxy equivalent should be a solid resin between 700-100, and the molecular weight distribution is narrow; At its curing temperature, the melt viscosity is low, easy to level, and the coating film is flat and thin; Good dispersibility to pigments and fillers.

Epoxy powder coating curing agents mainly include dicyandiamide, dicyandiamide derivatives, anhydride, imidazole, cyclic ether, phenolic resin, polyester resin, and boramine trifluoride complex. Industrially, dicyandiamides, imidazoles and cyclic ethers are generally used.

Epoxy resin is a general term for a class of polymers that contain more than two epoxy groups in the molecule.

Epoxy resin is actually a thermosetting resin, belonging to an organic chemical, its heat resistance, electrical insulation, strong corrosion resistance, and excellent chemical resistance, including the best alkali resistance, so it is widely used in decorative flooring.

The epoxy resin has strong adhesion to the paint film, and once the epoxy resin is cured, it can have a good bonding effect on the surface of metal materials and non-metal materials, and at the same time, it can also reduce the shrinkage rate. Epoxy resin is also relatively tough and has high hardness, so it is often used in defense and other industries.

Today, let's take a look at what epoxy resin paint is and the embodiment of the use and function of epoxy resin paint, and see what differences exist between epoxy resin paint and other coatings. Well, let's not talk about more, let's take a look at what epoxy paint is and the use and function of epoxy paint.

What is epoxy paint?

Epoxy resin paint, which is a coating with epoxy resin as the main film-forming substance, is an organic polymer compound containing two or more epoxy groups in the molecule, except for a few, their relative molecular quality is not high. The molecular structure of epoxy resins is characterized by the presence of active epoxy groups in the molecular chain, which can be located at the end, middle or cyclic structure of the molecular chain. Because the molecular structure contains active epoxy groups, they can cross-link with various types of curing agents to form insoluble, non-meltable polymers with a three-way network structure.

Epoxy resin paint use.

3. Used in factory equipment: anti-corrosion coatings for equipment and pipelines, outer coatings for refrigerators and washing machines, insulating coatings for electrical equipment, etc.; 4. Used in automobiles: chassis primer, component paint, tank car inner wall coating, etc.;

5. Used in ships: bottom warehouse inner wall coatings, marine container coatings, anti-corrosion coatings for steel parts, etc.

Epoxy resin paint effect.

1. Strong adhesion: epoxy resin contains polar groups such as hydroxyl and ether bonds, which makes the resin have strong interaction with adjacent interface molecules, and some can also form chemical bonds, so its adhesion is strong; 2. Good chemical resistance: cured epoxy resin contains a stable benzene ring, which generally has good acid, alkali and organic solvent resistance;

3. Small shrinkage: no by-products are produced in the reaction between epoxy tree imitation fat deficiency and curing agent, so the shrinkage force is small;

4. Good electrical insulation: cured epoxy resin has excellent electrical insulation;

5. Good stability: epoxy resin is not reinforcing agent, will not be cured by heat, will not deteriorate, and has good stability.

Conclusion: The use of epoxy resin paint is very wide, I don't know if everyone has noticed it. Well, I will introduce the relevant knowledge of epoxy resin paint here, and I believe that everyone has a certain understanding of epoxy resin paint, and I hope everyone will like this article I have organized.
