Abstract: The present invention relates to a contact adhesive composition based on chloroprene rubber, to a preparation method of the contact adhesive composition and to a method of bonding substrate by using the contact adhesive composition. In particular, the present invention relates to a contact adhesive composition comprising a fast-crystallizing chloroprene rubber and a slowly-crystallizing chloroprene rubber.

Abstract: The present invention is directed to a one-component (1K) moisture curable composition comprising: (a) at least one polyorganosiloxane which has at least one alkoxy group bound to a silicon atom, (b) at least one alkoxy-containing aminofunctional silicone resin, (c) at least one adhesion promoter different from said alkoxy-containing aminofunctional silicone resin (b), and (d) at least one curing catalyst. The invention also relates to coatings, sealants, or adhesives comprising said composition, cured products obtained from said composition, use of the composition.

Abstract: The present invention is directed to a two component (2K) composition comprising: (A) a first component comprising: a) at least one epoxy resin different from said resin b); and, b) at least one elastomer modified epoxy resin; (B) a second component comprising: c) a curative which consists of at least one compound possessing at least two epoxide reactive groups per molecule, said curative being characterized by comprising at least one alkoxy-containing aminofunctional silicone resin, wherein said composition is characterized in that it is free of catalysts.

Abstract: The present invention provides curable compositions that are substantially free of metal catalysts including both tin and non-tin metal catalysts. The curable compositions employ a catalyst composition comprising the combination of a (i) carbodiimide functional compound, and (ii) an amino-containing compound such as an amino silane functional compound and/or an organic amine compound. The combination of these materials, particularly when aged, accelerates the condensation curing of moisture curable silicones/non-silicones even in the absence of a metal-based catalyst.

Abstract: The present invention provides curable compositions comprising non-Sn organo-metal catalysts that accelerate the condensation curing of moisture curable silicones/non-silicones. In particular, the present invention provides Fe(III) and Bi(III) complexes that are particularly suitable as replacements for organotin for sealant and RTV formulations. The Fe(III) and Bi(III) complexes are comparable or superior to organotin such as DBTDL and exhibit certain behavior in the presence of components that allow for tuning or adjusting the cure characteristics of the present compositions and provide good adhesion and storage stability.
