WACKER T 37:
Organo-tin compound + silicic acid ester (dibutyl bis(1-oxoneodecyloxy)stannane
and tetrapropyl-orthosilicate)
WACKER CATALYST OL:
Platinum complex in polydimethylsiloxane < 5
% 1,1,3,3-tetramethyl-1,3-divinyldisiloxane platinum complex
Polydimethylsiloxane + filler, emulsion in water; contains approx. 1 % ammonium lauryl sulfate, < 5 % alpha-octadecyl-omega-hydroxy-polyglycol ether and < 5 % alpha-iso-tridecyl-omega-hydroxy-polyglycol ether
Polydimethylsiloxanes
Polydimethylsiloxane with vinyl groups
Room-temperature-vulcanizing rubbers, consisting of one part; i.e. the crosslinker is contained in the rubber and becomes active on exposure to atmospheric moisture.
Room-temperature-vulcanizing rubbers, consisting of two parts; crosslinking only starts when the two components are mixed together.
High-temperature-vulcanizing rubbers, consisting of high-molecular polydiorganosiloxanes with incorporated vinyl, alkenyl, phenyl or trifluoropropyl groups; vulcanization is performed by thermally cleavable peroxides; the peroxides may alternatively be cleaved by UV light or microwave radiation.
