COATINGS AND PLASTICS MATERIALS BAKEIITEVINYL CHLORIDE-ACETATE RESIN VMCH FOR SOLUTION COATINGS DESCRIPTION An acid modified vinyl chloride-vinyl acetate copolymer resin of medium-molecular weight. Solubility characteristics are similar to those of BAKELITE VYHH resin. BAKELITE VMCH resin is recommended for general coatings use either alone or in combination with other vinyl resins to obtain good air dry adhesion to metal, paper, and other substrates. This resin is listed by chemical identity in the Resinous and Polymeric Coatings Food Additive Regulations 121.2514.

PACKAGING AND LABELING The standard package for BAKELITE VMCH is a multi-wall paper bag containing 50 pounds of product. The package will be plainly marked with the product and blend numbers and the quantity of material contained. BAKELITE VMCH is also available in bulk; by hopper car containing approximately 150,000 pounds;and in certain geographic areas, by hopper truck containing approximately 40,000 pounds. SHIPPING AND STORAGE BAKELITE Vinyl Solution Resin VMCH is a stable material when kept in closed containers stored in a cool dry place. PRECAUTIONARY LABELING On the basis of the toxicological, physical, and chemical properties of BAKELITE Vinyl Solution Resin VMCH, precautionary labeling used on the containers is as follows: FOR INDUSTRY USE ONLY TOXICOLOGICAL PROPERTIES BAKELITE Vinyl Solution Resin VMCH is a powdered resin which is essentially inert and non-toxic. Its dust is classed as a nuisance dust which is not known to cause lung disease. However, it is prudent not to exceed the recommended Threshold Limit Value for nuisance dust of 10 mg. per cubic meter of air or 30 million particles per cubic foot, whichever is the smaller F-44259 11/72-4M Printed in U.S.A.
