Abstract:
The invention relates to a multicomponent, isocyanate-terminated or silane-functionalized coating and adhesive material that is continuously produced by mixing the individual components and by heating the latter and continuing mixing until said components reach a liquid state, wherein the resulting reactive coating and adhesive material is fed for direct use especially in profile sheathing plants, coating plants or the like. In the case of the isocyanate-terminated material, one component has a reactive high-molecular weight starting polymer and a second component has a reactive isocyanate-terminated cross-linking agent. In the case of the silane-functionalized material, one component has a high-molecular weight starting polymer and a second component has a reactive, silane-functionalized cross-linking agent.

Abstract:
Curable composition comprising a stable, water dispersible, curable polymer containing a sterically hindered alkoxylated silane group at 0.1 to 75 weight percent of the total composition; a water dispersible or water soluble, hydrolytically stable organometallic catalyst, at 0.1 to 10 weight percent of the total composition; and water at 99.8 to 24.9 weight percent of the total composition are taught herein. These compositions are useful as adhesives, sealants and paints. The compositions have improved properties including solvent resistance, adhesion, hardness, abrasion resistance and mar resistance. Particular catalysts for use herein include dihydroxy bis [2-hydroxypropanato (2-)-O1,O2] titanate mixed titanium ortho ester complexes, acetylacetonate chelate, bis(ethyl-3-oxobutanolato-O1,O3) bis(2-propanolato) titanium, alkanolamine complex of titanium and mercaptoalcohol, mercaptide or sulfide forms of diorganotins having either a Sn-S or Sn=S bond.
