Ethylene Vinyl Acetate Copolymer Emulsion In Water

Ethylene vinyl acetate emulsion.

Ethylene vinyl acetate copolymer emulsion in water.

Strong initial adhesion high wet tack good creep resistance water alkali resistance improved thickening response and safe operation. Eva emulsion is a general purpose copolymer water based emulsion that can be used in the film bonding paper bonding floor wall and ceiling adhesive. Polyvinyl acetate is synthesized by the emulsion polymerization of vinyl acetate monomer vam. Toughness vinyl acetate and flexibility ethylene.

There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. Polymerization leads to vae copolymers. Pvac emulsions are best known for their use in wood glues or school glues due to their strong adhesion properties. Water based adhesives for.

It has been developed as a powerful base adhesive offering the following unique characteristics. Vinyl acetate ethylene copolymer emulsion vae emulsion is a copolymer of vinyl acetate and ethylene. Generally vae copolymer emulsions can be used without additives or modifiers and ideally combine low environmental impact with effective performance in paints. Vinyl acetate ethylene vae is a combination of ethylene and vinyl acetate two monomers possessing special properties as e g.

Vae copolymers form the basis for engineering different properties in the individual end application. Vinyl acetate ethylene vae copolymers are water based emulsions that offer considerable performance advantages over polyvinyl acetate pva homopolymer adhesive glue due to the ability to alter their glass transition temperature tg c through the incorporation of ethylene monomer. However pvac emulsions are also widely used in many industrial and consumer end use applications. Vinyl acetate ethylene vae emulsions are based on the copolymerization of vinyl acetate and ethylene in which the vinyl acetate content can range between 60 and 95 percent and the ethylene content ranges between 5 and 40 percent of the total formulation.

Adhesive compositions consisting essentially of an aqueous emulsion of vinyl acetate ethylene copolymer prepared in the presence of protective colloid comprising fully hydrolyzed vinyl alcohol copolymer containing methyl methacrylate have improved water resistance. Series is a product line of water based emulsions for various forms of polymer compositions as typified by ethylene vinyl acetate copolymer resins ternary copolymer resins composed of ethylene vinyl acetate and vinyl chloride and acrylic ethylenevinyl acetate copolymer resins.
