Abstract
The invention provides contact adhesives comprising an adhesive component comprising polychloroprene rubber, and an internal coagulant. The contact adhesives may also contain a resinous component selected from the group consisting of ethylene-vinyl acetate copolymer, polyvinyl acetate homopolymer, polyvinyl acetate copolymer, acrylic copolymer, polyvinyl acetate acrylic copolymer, and combinations thereof. The internal coagulant may be hygroscopic salt, amino acid, or a combination thereof.
Claims18
A stabilized, one-part, water-based adhesive composition comprising:
- a) an adhesive component comprising polychloroprene rubber;
- b) a resinous component selected from the group consisting of ethylene-vinyl acetate copolymer, polyvinyl acetate homopolymer, polyvinyl acetate copolymer, acrylic copolymer, polyvinyl acetate acrylic copolymer, and combinations thereof;
- and
- c) an internal coagulant comprising from about 0.3 to about 1.2 percent by weight based on the dry weight of the adhesive component of an amino acid, wherein said adhesive composition is a contact adhesive composition.
