Vinyl Resin VAMA equivalent to H15/45M
A high molecular weight resin containing approximately 86 percent vinyl chloride, 13 percent vinyl acetate, and 1 percent maleic acid; VAMA(VMCH) 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 22 percent solids. VAMA vinyl resin is used primarily for air-dry finishes, such as maintenance, marine, and metal coatings, adhesive for aluminium foil , heat transfer foil, and is often used to make heat-sealable packaging coatings.
