US Patent:

47850418, Nov 15, 1988
Filed:

Dec 31, 1987
Appl. No.:

7/140265
Inventors:

Robert C. Antonen - San Ramon CA
Diane M. Rasch - Alameda CA
David A. Sierawski - Midland MI
David J. Romenesko - Midland MI
Assignee:

Dow Corning Corporation - Midland MI
International Classification:

C08K 524
US Classification:

524265
Abstract:

Thixotropic, silica-filled coating compositions wherein the curable film-forming material is an organosiloxane copolymer resin include a liquid polydiorganosiloxane containing hydroxyl-terminated polyoxypropylene units as the flow control agent. The compositions are particularly useful as screen printable passivation coatings for semiconductor devices.

US Patent:

58824677, Mar 16, 1999
Filed:

Oct 28, 1997
Appl. No.:

8/959661
Inventors:

David Alan Sierawski - Midland MI
Steven West Wilson - Midland MI
Beth Ann Witucki - Bay City MI
Assignee:

Dow Corning Corporation - Midland MI
International Classification:

B32B 3100
C09J 100
US Classification:

156329
Abstract:

The combination of reduced flammability and adhesion can be imparted to cured organosiloxane materials when the curable compositions used to prepare these materials contain 1) an adhesion promoting composition comprising up to about 0. 1 weight percent, based on the weight of the curable composition, of a chelated organoaluminum compound in combination with an organic epoxide compound and an alkoxysilane or condensation product of the silane, and 2) as a flame-retarding additive, hydrated aluminum oxide and/or magnesium hydroxide, preferably in combination with additional fillers such as quartz.

US Patent:

41222466, Oct 24, 1978
Filed:

Sep 21, 1977
Appl. No.:

5/835119
Inventors:

David A. Sierawski - Midland MI
Assignee:

Dow Corning Corporation - Midland MI
International Classification:

C08G 7704
US Classification:

528 15
Abstract:

Mixing vinyl-containing polyorganosiloxane, a silicon-bonded hydrogen containing organosilicon compound, a platinum catalyst, a polysiloxane having at least two silicon-bonded vinyl radicals and at least one silicon-bonded hydroxyl radical and an epoxy-containing, alkoxy silane provides a silicone gel which discolors less on aging than other platinum catalyzed silicone gels. An example of the polysiloxane is a hydroxyl endblocked polymethylvinylsiloxane and an example of the epoxy silane is ##STR1##.
