Method for preparing tin complex curing catalyst. |
摘要 |
<p>Catalysts containing tin complexes such as dibutyltin bis(acetylacetonate), useful as curing catalysts for room temperature vulcanizable compositions, are prepared by the reaction of a dialkyltin oxide with a dione and a polyalkoxysilane at a temperature in the range of about 20-80 DEG C. At least 2 moles of dione and preferably at least 2 moles of polyalkoxysilane are employed per gram-atom of tin. The polyalkoxysilane removes water of reaction, driving the reaction to completion.</p> |
