TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: (I) comprises disilyloxane units (a) (10-70 mole%) and siloxane units (1-80 mole%). The silicone composition further comprises at least one of a cross-linking agent and a condensation catalyst. Preferred Components: The particles have a median particle size of 0.001-500 mu m. The particles are silica particles, silicone resin particles, silicone elastomer particles or metal polysilicate particles. The coating has a thickness of 0.01-20 mu m. The film has a thickness of 10-3000 mu m. The fiber reinforcement is a woven fabric, a non-woven fabric or loose fibers. The fiber reinforcement comprises glass fibers. EXAMPLE - Disilane composition (containing chlorodisilane compound (in %) of formula (C4H9SiCH3Cl2) (7.1), ((CH3)3Cl3Si2O) (0.3), ((CH3)4Cl2Si2) (8.6), ((CH3)2Cl4Si2O) (1.9), ((CH3)3Cl3Si2) (1.9) and ((CH3)2Cl4Si2) (52.8), and 10C hydrocarbon (1.9%) obtained by fractional distillation of the residue produced in the direct process for manufacturing methylchlorosilanes) (30 g) was mixed with methyl isobutyl ketone (MIBK) (120 g) and anhydrous methanol (38.4 g). The hydrochloric acid produced from the reaction was allowed to escape from the open mouth of the flask. The liquid mixture was placed in a sealed bottle, chilled in an ice water bath, and then transferred to an addition funnel mounted on top of a flask. A mixture containing deionized water (120 g) and Organosilicasol IPA-ST (RTM: Dispersion of colloidal silica in isopropyl alcohol) (51.8 g) was placed in the flask and cooled to 2-4 degrees C. The mixture in the addition funnel was continuously added to the chilled mixture of deionized water/colloidal silica over 10 minutes, during which time the temperature of the mixture was increased by 3-5 degrees C. After completion of the addition, the mixture was stirred in the ice bath for 1 hour. The flask was then heated to 50-75 degrees C and held at that temperature for 1 hour. The mixture was allowed to cool to room temperature and then washed with a solution of sodium chloride (10 g) in water (200 ml), four times. After each wash the aqueous phase was discarded. The organic phase was isolated and concentrated at 60 degrees C and a pressure of 2.7 kPa to produce a solution containing 22.4 wt.% of the silicone resin in MIBK, where the mole ratio of SiO4/2 units to disilyloxane units in the resin is 4.4.
