Abstract:
The present invention comprises a polystannoxane catalyst, a curable composition containing the catalyst and a method of using the catalyst and curing the composition. The curable composition comprises:
(i) a blocked isocyanate; (ii) a functional component containing reactive hydrogen; (iii) a polystannoxane catalyst for promoting the reaction of the blocked isocyanate with the functional component. A co-catalyst may also be employed based on Cu, Zn, Ni, Zr, Ce, Fe, Co, V, Sb and Bi and especially oxides, salts or chelates of said metals. The invention also relates to a method for curing a blocked isocyanate at a low reaction temperature which comprises combining the catalyst with the blocked isocyanate and functional component and heating to a temperature less than about 180°C to obtain a cured urethane.
Abstract:
A fluorine-doped tin oxide coating is formed on glass using an organotin di- or tri-carboxylate with an organic fluoroacid. About 50-80% organotin compound and 20-50%. fluoroacid are used, applied in vaporised form to the heated glass surface. The resulting coatings have low bulk resistivities and Gardner haze values. The preferred compounds used are dibutyltin diacetate and trifluoracetic acid.
