Abstract:
1. A material system essentially free of silicone consisting essentially of the following components, or a mixture, a blend or a reaction product thereof: (i) a cationically curable material component comprising the backbones of a completely or substantially completely hydrogenated hydrocarbon based rubber material completely or substantially free of carbon-carbon double and triple bonds, wherein the cationically curable component is a functionalized material selected from the group consisting of: functionalized polybutadiene, functionalized polyisoprene, functionalized polyethylene propylene rubber and combinations thereof, and wherein the functionalized material comprises a backbone completely hydrogenated or substantially completely hydrogenated and completely or substantially completely free of carbon-carbon double and triple bonds; (ii) a hydroxyl-containing component having at least two hydroxyl groups per molecule; (iii) an initiator component having essentially no volatility at room temperature and also yielding products after polymerization that have minimal or no volatility at room temperature; (iv) an optional viscosity adjustment component either homopolymerizable or capable of copolymerizing with the cationically curable material component of (i); and (v) an optional non-alkaline inert filler; wherein when all the components are mixed together, the material system is thermally curable at around room temperature to form a rubbery polymer material that is low-outgassing at room temperature.
