Abstract: Gel formation is prevented in the reaction between a sulfonyl-chloride-containing resin and a polyamine by first forming an adduct between the resin with an aminophenol. The prevention of gel formation enables sulfonyl-chloride containing resin to be used in admixture with acrylates and epoxy resin to form a polyamine-curable adhesive composition having excellent adhesive properties and chemical resistance.

Abstract: A unique adhesive composition consisting of two parts, a resin and a curing agent, is disclosed. The composition has good adhesion to chemically inert substrates, both flexible and rigid. It is useful for sealing discontinuity in concrete slabs, tanks, decks, pipe lining or combinations thereof.

Abstract: A coating material for coating a substratehas been invented, the coating material including solvent, chlorosulfonated polyethylene dissolved in the solvent, hardener, and strengthener material. A process for producing a coating material for coating a substrate has been invented, the process including reacting chlorosulfonated polyethylene with an amino silane producing reaction product by the cross-linking of the chlorosulfonated polyethylene with the amino silane, adding carbon black to the reaction product, adding kaolin clay to the reaction product, and dissolving the reaction product, carbon black, and kaolin clay in a solvent forming a solution, the solution applyable to a substrate to form a coating thereon upon evaporation of the solvent.
