摘要： The invention proposes use of ammonia water in place of a conventional caustic alkali or amine compound as a catalyst in the siloxane rearrangement reaction for the preparation of a silicone-based pressure-sensitive adhesive between a poly(diorganosiloxane) having a linear molecular structure and another organopolysiloxane composed mainly of the monofunctional organosiloxane units and tetrafunctional siloxane units. The ammonia water after completion of the reaction can be easily and completely removed by distillation so that the resultant adhesive product is free from any alkaline residue of the catalyst to be imparted with greatly improved stability against viscosity changes and excellent electrical properties along with high reproducibility of the product quality.

摘要： Shaped aluminum bars fresh from an extruder machine are coated with a specific organopolysiloxane composition while remaining uncooled and staying at temperatures not lower than about 250.degree. C, or at a temperature between about 550.degree. and 250.degree. C. The thus coated aluminum bars are then, preferably, subjected to annealing. The coatings formed on the surfaces of the aluminum materials have a superior resistance to attack by chemicals, weather, stains and heat as well as excellent adhesion and mechanical properties.

摘要： An improved method for preparing epoxy-modified silicone resins is proposed in which the reaction catalyst is an alkali halide, such as sodium chloride and potassium chloride, or a combination of the alkali halide and an alkyl titanate, such as tetraisopropyl titanate and tetrabutyl titanate. The epoxy-modified silicon resin thus obtained is further reacted with a polybasic carboxylic acid or its anhydride. Varnishes containing these modified silicone resins can give coating films with very strong resistance to chemicals and solvents. Furthermore paints prepared with these varnishes as the vehicle are very stable, and exhibit no thixotropy even after a very long period of storage.
