Self-adhesive addition-crosslinking silicone compositions

The present invention relates to silicone rubber compositions and long-term-stress-resistant silicone elastomers obtained therefrom, which have excellent resistance to long-term dynamic mechanical stresses, and to their use.

Silicone rubber compositions and long-term-stress-resistant silicone elastomers obtained therefrom

Polyorganosiloxane compositions crosslinkable by addition of Si-bonded hydrogen to aliphatic carbon-carbon multiple bonds which have extended pot life or are preparable as storage stable one component compositions including latent catalysts of specific platinum complexes.

Crosslinkable polyorganosiloxane compositions

Platinum 1,3-diketo compounds are prepared by stirring a dichloroplatinum compound and a diketo compound in a keto solvent at below 10&#xb0; C. for from 5 minutes to 90 minutes and isolating the reaction product. The product is obtained in high purity suitable for use as a catalyst for preparing polymer articles suitable for use in the medical and food industries.

Primer for silicone rubber

Addition crosslinkable organopolysiloxane compositions employ specific rhodium catalysts. The compositions exhibit storage stability and crosslink effectively to provide highly transparent and colorless organopolysiloxane elastomers.

Cross-linking silicone elastomers, method for the production thereof, and use of the cross-linkable masses

Self-adhesive addition-crosslinking silicone compositions, contain two adhesion promoters, a first, multinuclear aromatic compound containing at least one moiety of aliphatic unsaturation, and a low viscosity organopolysiloxane having at least one terminal, silicon-bonded hydrogen. The addition curable materials exhibit strong adhesion to substrates, even substrates which have exhibited problematic adhesion to silicone elastomers in the past.

Shaped bodies comprise addition-crosslinked silicone elastomers crosslinked in the presence of at least one rhodium or iridium catalyst or mixtures of both catalyst types. The shaped bodies may be made transparent and colorless and are well suited for use as food and baking molds in the food industry. The catalyzed addition-crosslinkable components display excellent pot life as well as good high temperature cure.

Self-adhesive addition-crosslinking silicon compositions

Organosilicon compounds having alkynol groups and containing units of the formula where Rand Rare optionally substituted hydrocarbon radicals, Rare divalent organic radicals, and X is a linking group are useful in addition crosslinkable compositions. The compositions exhibit long pot life and yet also exhibit excellent cure, and are useful, inter alia, in preparing molded articles and coatings.

Curable organopolysiloxane materials

The invention relates to a method for producing Si&mdash;H containing siliconimides by achieving balanced proportions of organosilicon compounds containing Si&mdash;H groups, in siliconimides. It also relates to siliconimides containing Si&mdash;H groups and their applications as Si&mdash;H comb-crosslinking agents, as a constitutional unit for spread coating paper or electrical components, in adhesive material, moulding material, film material, coating material, laminated material, tough elastomers and composite matrix material.
