    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 ,O ] titanate mixed titanium ortho ester complexes, acetylacetonate chelate, bis(ethyl-3-oxobutanolato-O ,O ) 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.

    Abstract: Low viscosity moisture curable silicone compositions useful to protect surfaces from biofouling are described and they comprise an alkoxysilane stopped polymer, a silica based filler and a condensation catalyst. The alkoxysilane is preferably of formula where each R and R' is an organic substituent and is preferably methyl. These moisture cured compositions have a viscosity below 30,000 cps and a Mw of less than 100,000. The compositions may be used as protective coatings and/or caulks/sealants and may be applied by spraying, brushing and troweling.
