Vinyl Chloride-Vinyl Acetates Copolymer VCVA-2
Similar to VYHH of Dow Chemical
Characteristice: A high molecular weight resin having a composition of approximately 86 percent vinyl chloride and 14 percent vinyl acetate. VCVA-2 offers a desirable balance of chemical resistance, solubility, film strength, and thermoplasticity, has a good adhesion on paper, acrylic resin, PVC, ABS and PC, etc.
Solubility: VCVA-2 is usually dissolved in a relatively strong solvent/diluent combination, such as ketone solvent/aromatic diluent (50/50 percent by weight). With this system, a solids content of 20 to 25 percent can be achieved. Ketones and esters are the most commonly used solvents, and chlorinated hydrocarbons, amide used only in a few occasions. Ketones is a particularly good solvent, and esters is the relatively weak solvent. Chlorinated hydrocarbons such as dichloroethane and 1,2 - dichloroethane can completely dissolve VCVA-2, but methyl chloroform and tetrachloroethane can only swell it. Aromatic hydrocarbons have a good role in the swelling, generally using with ketone.
Application: It is ideally suited for marine and maintenance coatings, metal, can paint, strippable coatings, PVC and paper ink, magnetic card, cable, rubber and plastic foam materials, leather surface treatment, PU color plasm and flake, flooring, ciphertext disc, etc.
Description: Solution vinyl resin provides good adhesion to vinyl, metals, concrete and cellulosic substrates. This resin gives highly flexible, post-formable coatings on metal coil and sheet. Typical application used in a wide variety of clear and pigmented coatings on paper, film, foil and fabric. Useful in the production of heat sealable packaging coatings and adhesive.
