The present invention provides curable compositions comprising non-tin metal accelerators that accelerate the condensation curing of moisture-curable silicones/non-silicones. In particular, the present invention provides an accelerator comprising metal-arene complexes that are suitable as replacements for organotin in sealant and RTV formulations.

Moisture curable compound with metal-arene complexes

The present invention provides curable compositions comprising non-tin metal accelerators that accelerate the condensation curing of moisture-curable silicones/non-silicones. In particular, the present invention provides an accelerator comprising thiourea-containing compounds that are particularly suitable as replacements for organotin in sealant and RTV formulations. Further, this thiourea-containing compound is comparable or superior to organotin such as DBTDL, exhibits certain behavior in the presence of components that allow for tuning or adjusting the cure characteristics of the compositions, and provides good adhesion and storage stability.

Moisture curable compound with thiourea

The present invention provides curable compositions comprising non-tin metal accelerators that accelerate the condensation curing of moisture-curable silicones/non-silicones. In particular, the present invention provides an accelerator comprising amino acid compounds that are suitable as replacements for organotin in sealant and RTV formulations.

Moisture curable composition with amino acids

The present invention provides curable compositions comprising non-tin metal catalysts that accelerate the condensation curing of moisture-curable silicones/non-silicones. In particular, the present invention provides bismuth(III) sulfonate complexes that are particularly suitable as replacements for organotin in sealant and RTV formulations. In one embodiment, the present invention provides bismuth (III) camphorsulfonate and bismuth(III) methanesulfonate complexes. Further, these bismuth(III) sulfonate complexes are comparable or superior to organotin such as DBTDL, exhibit certain behavior in the presence of components that allow for tuning or adjusting the cure characteristics of the present compositions, and provide good adhesion and storage stability.

Moisture curable organopolysiloxane composition

A silane coating composition containing a silicon-based copolymer, a method for treating the surfaces of a metal such as steel, zinc-coated steels, or aluminum, to provide for the formation of a uniform conversion and/or passivation coating which increases the corrosion resistance of bare or painted metal and/or the adhesion properties of the metal, along with a metal having a conversion and/or passivation coating applied thereto are disclosed. Methods of the invention include contacting the requisite metal surface with an aqueous solution of a silane compound and a silicon-based polyether copolymer.
