Ethylene Vinyl Acetate Copolymer Emulsion Based Adhesive

A water based contact adhesive composition especially suited for high modulus laminates subjected to high temperature post forming com prising an aqueous medium containing 45 to 85 wt adhesive component consisting essentially of a 50 99 wt vinyl acetate ethylene emulsion copolymer of 10 50 wt toluene insolubles and 20 to 10 c tg and preferably prepared by the emulsion polymerization.

Ethylene vinyl acetate copolymer emulsion based adhesive.

This work proposed the design and fabrication method for t shaped dry adhesives based on stretchable ethylene vinyl acetate eva copolymer with strong normal adhesion strength up to 70 n cm 2. Ethylene vinyl acetate emulsion 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. 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. Ethylene vinyl acetate eva copolymers ethylene vinyl acetates are leading polymers for hot melt manufacturing due to their high versatility.

Our wide variety of base polymer emulsions for adhesives allows you to choose the exact properties required to meet specific end use requirements. We offer a full line of acrylic vinyl acrylic styrene acrylic vinyl acetate and vinyl acetate ethylene copolymer emulsions. Vinyl acetate ethylene copolymer emulsion vae emulsion is a copolymer of vinyl acetate and ethylene. Polymer products for building and construction.

The eva copolymer which is based on a high proportion of va greater than 60 is referred to as ethylene vinyl acetate rubber. Eva is an elastomeric polymer that produces materials which are rubber like in softness and flexibility. In the general formulation it can be combined with plasticizers solvents thickening agents extenders etc. Strong initial adhesion high wet tack good creep resistance water alkali resistance improved thickening response and safe operation.

Eva based hot melts are able to fulfill various requirements in applications such as packaging bookbinding or label sticking. It has been developed as a powerful base adhesive offering the following unique characteristics.
