Metal catalysts employed in the preparation of organyloxysilyl-functional, moisture curable polymers, are deactivated by cheating with specific chelating agents. Compositions containing the polymers exhibit improved storage stability.

Method for producing organyloxysilyl-terminated polymers

Multicomponent crosslinkable compositions based on organyloxysilane-terminated polymers free of toxicologically objectionable catalysts and isocyanates exhibiting good tensile shear strength are useful for adhesive bonding and sealing of substrates.

Multicomponent crosslinkable compositions based on organyloxysilane-terminated polymers

Weather resistant and water repellent surfacing compositions especially useful in roofing applications contain an alkoxysilane-terminated polymer and a reactive silane plasticizer containing a Chydrocarbon group. The surfacing compositions are of low viscosity and may be used without non-reactive plasticizers or organic solvents.

Coating composition for sealing surfaces

Moisture curable adhesives of high tensile shear strength contain an alkoxysilyl-terminated polymer and an alkoxy-functional silicone resin.

Cross-linkable materials based on organyl oxysilane-terminated polymers

The invention provides curable adhesives of high tensile sheer strength, which contain an &#x3b1;-silane-terminated polyurethane prepolymer containing low molecular weight polyether or polyester groups in the polymer backbone, and a silane-terminated polyether polymer containing polyether groups of higher molecular weight.
