Filed:

May 17, 1996

Appl. No.:

08/649504

Inventors:

Rolf W. Biernath - Roseville MN
Mark S. Konings - Minneapolis MN
Robert S. Reylek - Minneapolis MN

Assignee:

3M Innovative Properties Company - St. Paul MN

International Classification:

H01R 458

US Classification:

428447, 428209, 428450, 439 86, 525478, 525479, 528 15, 528 31, 528 32

Abstract:

The present invention relates to electronic assemblies which include an elastomeric member made of a cured, room-temperature curable polysiloxane composition. When the assemblies are used to electrically interconnect a first contacting site on a first electronic device to a second contacting site on a second electronic device, the stress-relaxation resistant properties of the elastomer enhance local contact force to maintain a reliable connection.

International Classification:

A61K006/08
C08K003/40

US Classification:

523/116000, 524/494000

Abstract:

The inventive dental composition comprises (a) a part A comprising at least one polyacid and at least one polymerizable component; and (b) a part B comprising water, wherein the composition further comprises an oxidizing agent, a reducing agent, and reactive fillers in at least one of part A or part B and wherein at least one of the polyacid, oxidizing agent, and reducing agent is in a disperse phase. The dental composition can be used in many dental applications and is particularly suited for use as a cement.

Jeff P. Tane - St. Paul MN

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

C08G 7708

US Classification:

528 15

Abstract:

The present invention provides shelf-stable RTV silicones which are useful for preparing sealants, caulks, adhesives, coatings, molding materials, lithographic plates, release liners and reflective sheets. The silicone composition of the present invention comprises: (a) a curable silicone polymer, e. g. , vinyl-containing organopolysiloxane, (b) a crosslinker, e. g. , organohydrogenpolysiloxane, (c) a platinum catalyst of the Karstedt type and (d) an amine stabilizer.

Appl. No.:

8/629864

Inventors:

Mark S. Konings - Minneapolis MN
Joel D. Oxman - Minneapolis MN

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

A61K 610

US Classification:

523109

Abstract:

The present invention provides an addition-curable composition containing an inorganic, organic or organometalic compound of palladium in an amount effective to reduce the amount of hydrogen gas evolved in the reaction of the composition. A preferred embodiment is a dental impression material composition comprising: (a) an addition-curable compound; (b) a crosslinker; (c) a platinum-containing catalyst; and (d) a palladium compound. This generally provides a positive gypsum model of, for example, a dental impression that is substantially free of pits.

International Classification:

C08L 8305

US Classification:

524862

Abstract:

The present invention provides novel hydrosilation-curable compositions, the cure of which can be monitored visually, comprising: (1) an ethylenic compound; (2) a compound containing silicon-bonded-hydrogen groups; (3) a hydrosilation catalyst; and (4) one or more cure-indicating dyes with light absorption in the visible spectrum that exhibit a color change in the presence of a silicon-bonded-hydrogen compound and a precious metal hydrosilation catalyst. The cure-indicating dye provides the composition with an initial pre-cure color and a different post-cure color. As a result of this change in color, the state of cure of the composition can be visually monitored.
