Vah Vinyl Resin Equivalent To Dow Vagh - China
price: contact company for price
Characteristice: A high molecular weight, partially hydrolyzed vinyl
chloride/vinyl acetate resin, made in a two-step process, having a
composition of approximately 90 percent vinyl chloride, 4 percent vinyl
acetate, 6 percent vinyl alcohol, with a hydroxyl content of
approximately 2.3 percent.
VAH has excellent adhesion on PET, resin
primer, paper, PVC, ABS, pre-treatment of PE and OPP.
VAH 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 VAH 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 , obtaining excellent chemical and water resistance.
Solubility: VAH can be dissolved in relatively strong solvent/diluent
combinations, such as 50 percent ketone/50 percent aromatic hydrocarbon,
to produce resin solutions of 22-25 percent solids.
Ketone is a
particularly good solvent, and esters is the relatively weak solvent.
Chlorinated hydrocarbons such as dichloroethane and 1, 2 - dichloroethane
can completely dissolve VAH, and methyl chloroform and tetrachloroethane
can only swell it.
Aromatic hydrocarbons have a good role in the
swelling, generally using with ketone.
Application: VAH can be used for
a wide range of coatings applications, including marine anti-corrosion
paint, gravenu ink, chassis paints, maintenance, PU and wood finishes,
paper coatings, PET inks, interbedded adhesive, adhesive for magnetic
tape and carbon ribbon.
