Thermostatic fluids (-50ºC to +200ºC),
Anti-blotting products for photocopying machines, Thinning and plastifying agents for RTV's and silicone sealants, Raw material for Antifoam Lubricating and heat protecting agents for textile threads ( synthetic sewing threads), Ingredients in maintenance products (polishes, wax polishes, floor and furniture polishes, etc.), Paint additives (anti-cratering, anti-floating/flooding and anti-scratching effects, etc.), Water repellent treatment: -of powders (for paints and plastics), -of fibers: glass fibers, Release agents (mould release of plastics and metal castings), Lubricants (lubrication of elastomers or plastics on metal), Surfactants for styrene-butadiene foam. HCR application to reduce hardness |
Properties:
|
Very good resistance to high and low temperature,
Good combustion resistance, Low surface tension, High compressibility, Absence of ageing upon exposure to atmospheric agents, Good oxidation resistance, Little change in viscosity with temperature, Good resistance to high and prolonged shear stress.Thinning agents for RTV's and silicone sealants ( Two component, room temperature vulcanizing silicone elastomers); Coating additive to improve flowablity. |
