Property

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.
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

Application

Used for 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
