    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-)-O.sup.1,O.sup.2 ] titanate, mixed titanium ortho ester complexes, acetylacetonate chelate, bis(ethyl-3-oxobutanolato-O.sup.1,O.sup.3) bis(2-propanolato) titanium, alkanolamine complex of titanium and mercaptoalcohol, mercaptide or sulfide forms of diorganotins having either a Sn--S or Sn.dbd.S bond.

    Abstract: A component A, including at least one organic silane-group-containing polymer, at least one drying agent, at least one amine having at least one free amino group or latent amino group releasable via hydrolysis, at least one hydrolysable silane without an amino group, and at least one catalyst for crosslinking silane-functional polymers; and including a component B, including between 1 and 75 wt. % water dispersed in a mixture together with filler and/or plasticiser and further additives; and including further additives in component A and/or component B, from the group of fillers; wherein the catalyst is a tin complex having two mercaptide ligands according to formula (V), where ligands L1 independently represent sulfur-coordinated alkyl mercaptides, where ligands L1 include methyl dialkoxysilane groups, methyl dimethoxysilane groups, and ligands L2 independently represent alkyl ligands. The composition allows an exceptionally long pot time and simultaneously very rapid curing and excellent storage stability.
