Patent ID: 8685159

Claim:
A process for forming an adhesive bond between a mortar composition and an article composed of a polymer plastic material, which process comprises: providing a mortar composition that includes mortar and a surfactant composition; which surfactant composition includes a) about 30 to about 75 weight percent of a surfactant selected from the group consisting of alkyl sulfosuccinates, salts of alkyl sulfosuccinates, and mixtures thereof; and b) carrier particles composed of an absorbent material selected from the group consisting of calcium carbonate, calcium silicate, silicon dioxide, kaolin, and mixtures thereof; which carrier particles have a mean average particle size of about 0.1 to about 1000 micrometers and a capacity for carrying an amount by weight of the surfactant that is about 0.2 to about 5 times the weight of the carrier particles; blending the mortar composition with water to produce a wetted mortar composition; and establishing physical contact between the wetted mortar composition and an article composed of a polymer plastic material at conditions effective for curing of the mortar composition, thereby forming an improved adhesive bond between the mortar composition and the article.
