| SILRES® HK 46 is a methyl group containing silicone resin solution in xylene/n-butanol 4:1. Properties: SILRES® HK 46 is typically used in heat resistant coatings. It combines outstanding heat resistance and weatherability. With proper coating formulation, thermal stability up to 600°C (1100°F) can be achieved in combination with suitable temperature stable pigments and fillers. Special features: - good balance of flexibility, hardness, heat resistance and curing speed
- low viscosity
- air-drying
- limited compatibility (preferably used as a sole binder)
- excellent hydrophobicity and corrosion-protection
Application: SILRES® HK 46 is suitable for all kinds of heat resistant paints. It is an excellent choice for (anticorrosion)coatings on mufflers, exhaust systems, engine parts, boilers, furnaces, ovens and oven inserts, chimneys, barbeques and electric and gas heaters, incinerators. At temperatures above 250°C (480°F) the organic groups of silicone resins start to degrade. After all the organic parts of the silicone resin have been pyrolytically decomposed, the product that remains moves to an inorganic stoichiometric composition of (SiO2)n. It is this layer which firmly binds pigments and fillers to the coated substrate.Information provided by Wacker Chemie AG. |
