The present invention comprises a curable composition comprising:

Catalyst for low temperature cure of blocked isocyanates

Liquid methyltin halide compositions and their use as intermediates in chemical synthesis and as precursors for forming tin oxide coatings on substrates are disclosed.

Liquid methyltin halide compositions

The present invention comprises a curable composition comprising: (i) a blocked reactive component comprising a blocked isocyanate or a blocked isothiocyanate; (ii) a functional compound containing reactive hydrogen; (iii) a triorganotin catalyst for promoting the reaction of the blocked reactive component with the functional compound. The composition may also be admixed with water. The invention also relates to a method for curing a blocked isocyanate or blocked isothiocyanate at a temperature below about 150.degree. C. which comprises combining a triorganotin compound with the blocked reactive component and functional compound and heating at a temperature less than about 150.degree. C. to obtain a cured urethane or thiourethane.

This invention relates to heat and light stabilizer compositions for vinyl halide resin compositions comprising organotinthioalkanol compounds that are stabilized against gelation and precipitation, to methods of preparing the stabilizer compositions, and to stabilized vinyl halide resin compositions.

Liquid organotinthioalkanol stabilizer compositions and vinyl halide

Non-toxic organotin catalysts containing at least one direct oxygen-to-tin bond and one direct carbon-to-tin bond are provided for use as esterification catalysts in the production of non-toxic polyester and polyester-containing compositions. Articles made from such polyester and polyester-containing compositions are suitable for use in regulated food, beverage, pharmaceutical, and medical-device applications.
