Patent number: 4548999Abstract: A composition which is heat curable to give an elastomer of improved properties comprising(a) an organopolysiloxane polymer having a viscosity of 1,000,000 to 200,000 mPas at 25.degree. C. and comprising the structural unit ##EQU1## wherein R is a hydrocarbon radical or a halohydrocarbon radical, anda is between about 1.95 and 2.01,(b) a polycarbodiimide-polysiloxane copolymer comprising a polysiloxane continuous liquid phase containing a discontinuous phase of finely dispersed polycarbodiimide particles produced by condensing a diisocyanate in the polysiloxane,(c) a curing catalyst, and(d) a filler,the polycarbodiimide comprising about 0.1 to 80% by weight of (a) plus (b). Upon curing, the permanent set of the elastomer is reduced and/or the resistance to hydrolytic degradation is improved.Type: GrantFiled: February 5, 1981Date of Patent: October 22, 1985Assignee: Bayer AktiengesellschaftInventors: Helmut Steinberger, Hans-Heinrich Moretto, Werner Michel, Wilfried Kniege

Patent number: 4530977Abstract: An hydroxy-functional polyurethane reaction product is disclosed which enables the provision of thermosetting solution coating compositions which cure at low temperature to form flexible coatings. These polyurethanes are provided by the reaction of an organic diisocyanate with a stoichiometric excess of an essentially linear hydroxy-functional polyester which is the polyesterification reaction product of C.sub.4 -C.sub.10 aliphatic dicarboxylic acid or anhydride thereof with a stoichiometric excess of C.sub.3 -C.sub.8 aliphatic diol providing an alcohol/acid molar ratio of 3/2 to 6/5. The reaction is substantially complete as indicated by an acid number less than 10, and the diisocyanate is used in an amount providing an NCO/OH ratio of from 2/3 to 12/13. The thermosetting solution coating composition is provided by an organic solvent having dissolved therein from 5-50% of total resin solids of a curing agent reactive with hydroxy groups together with the polyurethane which has been described.Type: GrantFiled: July 30, 1984Date of Patent: July 23, 1985Assignee: DeSoto, Inc.Inventors: Ronald J.
