Product Description
Characteristice: A high molecular weight resin containing approximately 86 percent vinyl chloride, 13 percent vinyl acetate, and 1 percent maleic acid. Because of the carboxyl functional group, VAMA has excellent adhesion on metal, especially on aluminum foil, the resin foil also has a good adhesion on PVC, ABS, paper, textiles, beton, etc. At the same time, VAMA has good water resistance, excellent oil, ester, acid, alkali and salt water solution resistance.
Solubility: VAMA is usually dissolved in relatively strong solvent/diluent combinations, such as ketone/aromatic diluent (50/50 percent by weight), to produce solutions of 22 to 25 percent solids. Ketones and esters is 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 VAMA, and methyl chloroform and tetrachloroethane can only swell it. Aromatic hydrocarbons have a good role in the swelling, generally using with ketone.
Application: VAMA is used primarily for air-dry finishes, such as maintenance, marine and metal coatings, aluminum foil varnish, cans sealed paint, shoe adhesive, floor paint, cement paint, silk screen printing and transfer ink. VAMA often mixes with LC-40, used in the production of heat sealing packaging coatings, can effectively reduce the heat sealing temperature, raise the heat sealing strength. It also can be used to produce the VC sealing plastic package, Electro-chemical aluminum paint, thermal transfer adhesive.

Covering an area of 20, 000 square meters, our factory was established in 1998, located in the ancient historical city of Huizhou County, with the fixed assets of 2500 million yuan. We are professional manufacturer for vinyl chloride - vinyl acetate copolymer. The annual production capacity of the various grades of vinyl resin up to 15, 000 tons.
Through self-development as well as cooperate with other major institutions, we obtained advanced technology. Using advanced production technology and scientific management methods, we have a complete set of quality assurance system, passed the ISO9001: 2000. We never bring mass loss to the customers since we founded more than ten years, our quality has always been maintained stable.
Our products can replace DOW SVR series, such as DOW's VYHH, VMCH, VAGH etc. Mainly used in metal, wood, PET film, plastic, paper, leather, concrete, transparent and colored coatings, and other materials.
With the spirit of "quality first, reputation first" principle, we provide quality products with low prices to all kinds of customers, such as the pharmaceutical packaging aluminum foil, aluminum foil varnish, anodized aluminum, coatings, magnetic card material, thermal insulation materials, floor, carpet, plastic inks, ink for high temperature cooking, aluminum foil printing ink, leather surface treatment, PU color ointment, plastic paint, toy paint, UV paint, Wood, ranked nail glue, shoe adhesives, interlayer adhesive, adhesive for carbon ribbon and magnetic tape manufacturers.
Our company can produce different degree of polymerization and different components vinyl resin according to customer's requirements.
