Sumikaflex
Copolymer
type:

450HQ

Ethylene-Vinyl acetate Copolymer Emulsion

Properties:

S-450HQ is high viscosity emulsion. It has miscibility for anyadditive. It has good adhesion. Its viscosity is easily increased
by organic solvent or thickener. It has good properties foradhesion of wood, especially for wood or decorative laminatedplywood.
