strength enhancers of adhesives for cementitious compositions. the present invention relates to an adhesive bond strength enhancer for mortar, cementitious adhesive. the adhesion intensifier improves the bond strength between the mortar and an expanded polystyrene plastic material of the type generally used in an external insulating finishing system ("eifs"). there is also the preparation of solid, free-flowing, non-agglomerable dialkyl sulfosuccinate compositions for use as the adhesion enhancer. the adhesion intensifier is attractive for large-scale application in dry mixes of mineral mortar or other solid building materials. the invention can be used to improve the resistance of an adhesive bond between a) gypsum plaster or plaster and concrete or bricks, b) tile and concrete adhesives, and c) mineral mortars on polystyrene plates, among others. |
