  • Single-component polysulphide based sealant compositions
    Patent number: 5409985
    Abstract: A one-part polysulfide sealant composition comprises a mercaptan-terminated liquid polysulfide, an oxidising agent to cure the catalyst a desiccant such as a molecular sieve, to keep the composition dry and thus prevent premature activation of the catalyst, and a cure accelerator having an acrylate or methacrylate functionality of 2 or more, preferably an acrylated liquid polysulfide or a polyfunctional methacrylate monomer.

  • Acrylic rubber composition
    Patent number: 5405908
    Abstract: An improvement is proposed for an acrylic rubber composition to decrease the stickiness of the rubber composition under processing and shaped and vulcanized articles of the composition to a metallic surface with which the rubber article is kept in contact at an elevated temperature under compression as is the case in packings, gaskets and O-rings as automobile parts. The improvement can be obtained by compounding the rubber composition consisting of an acrylic rubbery polymer, which can be substituted by organosilicon groups, and a reinforcing filler with a limited amount of a specific diorganopolysiloxane, e.g., dimethyl polysiloxane, of which from 5 to 50% in number of the organic groups bonded to the silicon atoms are phenyl groups.
