Materials

Two vinyl acetate‐ethylene copolymer emulsions produced by high‐pressure reaction are the first of this product type to be manufactured in the U.K. The emulsions, Vinamuls 3240 and 3250, incorporate ethylene and other gaseous monomers, and are expected to find application in adhesives and binders, surface coatings, and textile and paper finishes, in which they require little or no compounding. Vinyl acetate — ethylene emulsions strongly adhere to most plastics and synthetic fibres and bond PVC films because of their resistance to plasticiser migration. The emulsions are able to form coherent films at low temperature without the addition of coalescing solvents, and ensure flexibility at low temperatures.
