Products: Vinyl resin VAMA

Carboxyl-Modified Vinyl Chloride/Vinyl Acetate Copolymers VAMA

 

Character:

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 aluminium foil, the resin foil also has a good adhesion on PVC, ABS, paper, textiles, beton, etc. At the same time, VANA has good water resistance, excellet oil, ester, acid, alkali and salt water solution resistance.

 

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 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.
