Abstract
A method of bonding a vulcanized elastomer is provided comprising the steps of; providing an adhesive comprising a primary acrylate monomer, a reactive flexibilizing monomer, and further optionally comprising a toughener, an adhesion promoter and a free radical initiator, then depositing the adhesive on at least one surface of an elastomer or a second substrate, wherein the elastomer is a vulcanized elastomer, then bringing the elastomer substrate and second substrate together with the adhesive disposed therebetween, and allowing the adhesive to cure and bond the elastomer and second substrate together at a temperature of less than about 100° C. to produce a bonded structure.

A method of bonding a vulcanized elastomer comprising the steps of:
- a) providing an adhesive comprising a primary acrylate monomer, a reactive flexibilizing monomer, and further optionally comprising a toughener, an adhesion promoter and a free radical initiator;
- b) depositing the adhesive on at least one surface of an elastomer or a second substrate, wherein the elastomer is a vulcanized elastomer;
- c) bringing the elastomer substrate and second substrate together with the adhesive disposed therebetween;
- and,
- d) allowing the adhesive to cure and bond the elastomer and second substrate together at a temperature of less than about 100° C. to produce a bonded structure.
A method for lining a tank comprising:
- a) providing a metallic tank;
- b) providing a cured (vulcanized) elastomeric lining material;
- c) depositing an adhesive to at least one of the lining material or the tank, wherein the adhesive comprises an acrylic adhesive;
- d) positioning the lining material upon an interior portion of the tank such that the adhesive is disposed therebetween;
- e) allowing the adhesive to cure and bond the lining material to the tank.
