EVA Emulsion Good Materials For Construction

EVA emulsion is a kind of adhesive, which has good adhesion properties, aging resistance, light resistance and saponification resistance. Suitable for use as floor, wall and ceiling adhesive. EVA emulsion is mainly used in adhesives, coatings, cement modifiers and paper processing, and has many excellent properties.

1. EVA emulsion has permanent flexibility.

EVA emulsion can be regarded as the internal plasticization product of polyvinyl acetate emulsion. Because it introduces ethylene molecular chain in the polyvinyl acetate molecule, it causes discontinuity of the acetyl group, increases the rotation freedom of the polymer chain, and hinders space. Small, the polymer main chain becomes soft, and plasticizer migration does not occur, ensuring the permanent softness of the product.

2. EVA emulsion has good acid and alkali resistance.

VAE emulsion can maintain stable performance in the presence of weak acid and weak base, so no matter it is mixed with weak acid or weak base, it will not demulsify, and the product has a wide range of applications.

3. EVA emulsion is resistant to UV aging.

Because the VAE emulsion uses ethylene as the internal plasticizer of the copolymer, the VAE polymer has internal plasticization, and the plasticizer will not migrate, thereby avoiding polymer performance aging. Therefore, not only the VAE emulsion has good stability to ultraviolet rays, but the VAE emulsion can also maintain this characteristic after the film is formed.

4. EVA emulsion has good compatibility.

VAE emulsion can be mixed with most additives, such as dispersant, wetting agent, antifreeze, defoamer, preservative, flame retardant, etc., so it can meet various needs; VAE emulsion can be mixed with many pigments and fillers, Without agglomeration phenomenon; VAE emulsion can be directly mixed with many low molecular and high molecular water-soluble polymers, such as polyvinyl alcohol aqueous solution, polyethylene glycol aqueous solution, starch or modified starch gelatinization liquid, sodium polyacrylate aqueous solution, Polymaleic acid aqueous solution, polyoxyethylene aqueous solution, urea-formaldehyde, phenolic aqueous solution, hydroxyethyl cellulose, carboxymethyl cellulose, methyl cellulose aqueous solution, etc.; VAE emulsion can be directly mixed with many other polymer emulsions, such as poly Vinyl acetate emulsion, polyacrylate emulsion; EVA emulsion can be directly mixed with aldehydes, esters, ketones, organic acids, polyols, higher alcohols, halogenated hydrocarbons, aromatic hydrocarbons, etc., such as formaldehyde, glyoxal, and phthalic acid Butyl ester, dioctyl phthalate, acetic acid, carbon tetrachloride, chloroform, benzene, toluene, xylene, octanol, ethylene glycol, glycerol, ethyl acetate, butyl acetate, etc.

5. EVA emulsion has good film-forming properties.

Emulsion adhesives can only form a transparent film at a certain temperature, which is called the minimum film forming temperature. The minimum film-forming temperature of VAE is generally lower than 5℃, so it can form a good film, and the film has a good barrier to water droplets.

6. EVA emulsion has good adhesion.

 It has a good bonding effect on fiber, wood, paper, plastic film, aluminum foil, cement, ceramics and other products.
