<p>1,093,454. Laminates. DOW CORNING CORPORATION. April 15, 1965 [May 18, 1964], No. 16280/65. Heading B5N. A process for making a composite article comprises (1) laminating to (A) transparent, non-elastomeric solid sheets with a melting point of over 150‹ C., a layer (B) of transparent uncured siloxane elastomer containing from 0À5 to 10% by wt. calculated on (B) of a lower alkyl orthosilicate or polysilicate, (2) laminating to (B) a layer of (C) transparent, uncured silicone elastomer containing no lower alkyl silicate, (3) assembling a laminate of (A), (B) and (C) with a laminate of (B) and (A) or (C), (B) and (A), so that the resulting structure is composed of layers in the order (A), (B), (C), (B), (A) or (A), (B), (C), (C), (B), (A), so that between any two layers of (A) the combined thickness of the (B) layers is not more than twice that of (C) and (4) heating the assembly to cure the silicone elastomer. " Lower alkyl " is defined as being an alkyl radical containing less than 7 carbon atoms. Specified transparent solid sheets are glass and fused quartz.</p> |
