Characteristice:A high molecular weight copolymer resin containing approximately 81
percent vinyl chloride, 4 percent vinyl acetate, and 15 percent
hydroxyalkyl acrylate, with the hydroxyl content at 1.8 percent.
VAF has excellent adhesion on paper,polysulfone resin,acrylic
resin, PVC, ABS, PC and the surface of ink.
VAF has good compatibility with other film-forming material, such
as alkyd resins, polyurethane elastomers, isocyanate resin,
melamine resin, urea-formaldehyde, epoxy polymers and so on. So VAF
often used with other film-forming material in order to improve the
coating performance, and enhance paint adhesion, flexibility,
tenacity, hardness and chemical resistance. The hydroxyl functional
group permits crosslinking reactions for thermoset coating systems
that exhibit outstanding chemical and water resistance.
Solubility: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
VAF, and methyl chloroform and tetrachloroethane can only swell it.
Aromatic hydrocarbons have a good role in the swelling, generally
using with ketone. VAF can be dissolved in relatively strong
solvent/diluent combinations, such as 50 percent ketone/50 percent
aromatic hydrocarbon, to produce resin solutions of 20-22 percent
solids. VAF resin solution viscosity and other characteristics is
very similar to VAH.
Application:VAF can be used for a wide range of coatings applications,
including maintenance and marine finishes, paper coatings, metal
finishes, PET inks, wood, plastic coatings,and adhesive for
magnetic tape and carbon ribbon.
