Silicone rubbers curing agents

OTHER COMMENTS used as a bleaching agent for flour, fats, oils, and waxes used as a catalyst for hardening of certain fiberglass resins useful in the treatment of acne and rosacea principally an initiator for vinyl chloride polymerizations also used as a curing agent for silicone rubbers an agent in the production of cheese. 

Uses. There are about forty to fifty organic peroxides commercially available in more than seventy formulations designed for specific applications which include (1) initiators for vinyl monomer polymerizations, and copolymerizations of monomers such as vinyl chloride, ethylene, styrene, vinyl acetate, acrylics, fluoroolefms and buta-dienestyrene (2) curing agents for thermoset polyesters, styrenated alkyds and oils, silicone rubbers and poly allyl diglycol carbonates ... 

PETN mixed with uncured Sylgard 182 silicone rubber and curing agent at 80% PETN and 20% rubber, forms a thick viscous material that can be extruded... 

Use Rubber accelerator, component of a catalyst system for polymerization of vinyl monomers, curing agent for water-repellent silicone materials, agent for plating with zirconium. 

The most important crosslinking agent for pressureless hot air vulcanization of silicone rubber is DClBP(Bis-2,4-dichloro-benzoyl-peroxide) (Fig. 14). It generates decomposition products, which are removed in a post-curing process with air blowing. This product provides the advantage of a fast cure rate and bubble-free cured transparent rubber.

Before fabrication it is necessary to compound the gum with fillers, a curing agent, and other special additives on a two-roll mill or in an internal mixer (see Rubber Compounding, Chapter 2). Unfilled polymers have negligible strength, whereas reinforced silicone rubbers may have strengths up to 2000 psi (14 MPa).
