AQUEOUS, SILYLATED AND CURABLE POLYMER COMPOSITIONS

摘要

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.
