Properties
iSuo
™ VAH-N is
hydroxyl modified ternary copolymer of vinyl chloride, vinyl acetate & vinyl
alcohol. Molecular weight: 27000. It is soluble in correspondingly strong solvent & thinner
composition, for example, 50% ketone & 50% aromatic hydrocarbon, producing 20% (solid
count) resin solution. VAH-N has very good mutual solubility with other filmforming matter,
for example, alkyd resin, polyurethane elastomer, carbimide acetate resin, epoxy polymer,
melamine resin, urea - formaldehyde resin, etc. It is often used with other filmforming matter,
to improve paint performance, reinforce the adhesive power, flexibility, tenacity, hardness &
chemical resistance of paint
