Carboxyl-Modified Vinyl Chloride/Vinyl Acetate resin VAMA(VMCH)

Carboxyl-Modified Vinyl Chloride/Vinyl Acetate resin VAMA(VMCH)

The carboxyl-modified vinyl chloride/vinyl acetate copolymers are
made specifically for the

formulation of coatings having excellent adhesion to various
substrates, especially metals, cellulosics,and certain plastics.
A high molecular weight resin containing approximately 85 percent
vinyl chloride, 14percent

vinyl acetate, and 1 percent maleic acid; VAMA solution vinyl resin
is usually dissolved in relatively strong solvent/diluent
combinations,such as 50 percent ketone/50 percent aromatic
hydrocarbon, to produce solutions of 20 to 22percent solids. VAMA
solution vinylresin is used primarily for air-dry finishes, such as
maintenance, marine, and metal coatings, and is often used to make
heat-sealable packaging coatings.
