The method of this invention produces a silicone coated glass fabric which is translucent or transparent as desired and which has a smooth dry surface. The coated glass fabric is useful in producing air-supported and tension-supported roofs for structures such as greenhouses. A glass fabric is first coated with a polydiorganosiloxane, in which the organo radicals are methyl and phenyl radicals in a ratio of from 0.25 to 3.7, in an amount sufficient to impregnate the fibers in the yarns of the fabric, but leaving the interstices of the fabric open. This first layer is then followed by coating with a polydimethylsiloxane elastomer to give a continuous layer, then coating with an elastoplastic organopolysiloxane resin to give a smooth, dry surface on the glass fabric reinforced sheet.

Clear silicone coated fabric

The method of this invention produces a silicone resin-coated fabric comprising an elastoplastic organopolysiloxane resin coated silicone elastomer membrane reinforced with fabric. The elastoplastic organopolysiloxane resin and the silicone elastomer membrane form an interface which is an adhesive bond derived from a combination comprising (i) polydiorganosiloxane of the formula X(R.sub.2 SiO).sub.a SiR.sub.2 X, (ii) a hydroxyl radical containing, solid, benzene soluble resin copolymer consisting essentially of R.sub.3 SiO.sub.1/2 units and SiO.sub.4/2 units, and (iii) a condensation catalyst for (i) and (ii). The bond between the layers of the silicone resin-coated fabric is of such a quality that the silicone resin-coated fabric can be adhesively bonded to itself, or another surface, to produce useful structures such as air supported roofs or tension supported roofs.

Flexible silicone resin coated fabric

This invention relates to a solar radiation reflector which can be fabricated from readily available, relatively low-cost materials with a minimum of effort and materials. The reflector consists essentially of a laminate of (A) at least one reflective metal foil layer possessing a weather-resistant protective coating on its reflective side and (B) at least one layer of cellulosic material impregnated with a weather-resistant cured polymer composition. Preferably, the metal foil is aluminum foil coated with a weather-resistant coating of silicone resin and the cellulosic material is a single layer of corrugated cardboard impregnated with a weather-resistant silicone resin composition.
