TECHNICAL DATA SHEET of
V A M
( similar to VMCH of Dow Chemical )

Description:
It is a high molecular weight, by carboxyl modified terpolymer comprised of vinyl chloride, vinyl acetate and maleic acid. It is supplied as a powder, the vinyl chloride content is about 86%, while the carboxy level is 1.0%.

Introduction:
It provides good adhesion to vinyls, metals, concrete and cellulosic substrates. This resin gives highly flexible, post-formable coatings on metal coil and sheet.

Application:
it mainly be used for dry surface paint, like repair paint, marine paint, and metal paint. Also it can be used for make the paint of heat sealable packaging, like the VC heat seal adhesive for medicine packing.

Typical applications:
Used in a wide variety of clear and pigmented coatings on paper, film, foil and fabric.
Useful in the production of heat sealable packaging coatings and adhesives.
Can be used in metal coatings and marine and maintenance coating.
Coatings for metal food cans.
FDA approved for use in food contact applications.

Features:
Produces highly flexible post-formable coatings on metal coil and sheet;
Adhesion to vinyl, metals, concrete and cellulosic substrates;
FDA approved for food contact applications;
