Hydroxyl-Modified Vinyl Chloride,Vinyl Acetate Terpolymers EMP-MVAD

Hydroxyl-Modified Vinyl Chloride/Vinyl Acetate Terpolymers EMP-MVAD is white powder,ketone soluble with colorless,transparent solution and has excellent adhesion on PET,resin primer,paper,PVC,ABS pre-treatment of PE and OPP.It is 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. 

Application:

EMP-MVAD can be used for a wide range of coatings applications,including marine anti-corrosion paint gravure printing inks,chassis paints, maintenance, PU and  wood finishes, paper coatings, PET inks, interbedded adhesive, adhesive for magnetic tape and carbon ribbon.
