| Product description: SILRES® MSE 100 is the methyl ester of a mixture of different oligomeric methylsilicates. It is a methoxyfunctional methyl polysiloxane. Properties: SILRES® MSE 100 is recommended as an ambient temperature moisture-curing binder for heat resistant paints. In combination with suitable catalysts and temperature stable pigments and fillers, SILRES® MSE 100 is the optimum binder for ambient curing, heat resistant paints. The curing rate depends on the catalyst used and on the relative humidity. After paint application and paint drying, coatings based on SILRES® MSE 100 can withstand temperatures of up to 650°C (1200°F) without loosing adhesion. Special features: - low viscous liquid, solvent free silicone binder (solvent content < 2%)
- very high inorganic content (corresponds to 68 - 72% SiO2)
- curable at ambient temperature within less than 15min
- almost no smoke generation upon initial stoving
- limited compatibility (preferably used as a sole binder)
Application: SILRES® MSE 100 is the binder of choice for all heat resistant coatings between 200°C (400°F) and 650°C (1200°F) which have to cure at ambient temperature prior to heat exposure. In many applications the major target of the coating is to provide corrosion resistance to the steel or aluminum substrate. Corrosion resistance can be further improved if a zinc-rich ethylsilicate is used as a primer (thereby lowering maximum operation temperature to around 420°C). Maximum heat resistance depends on the paint formulation, especially on the pigments used. A maximum temperature up to 650°C (1200°F) is observed for silver-coloured aluminum pigments and about 500°C (930°F) for black pigments. Others colors are possible as well.- automotive, motor-bike and aircraft parts (e. g. exhaust systems, mufflers, engine parts)
- industrial coatings (Chimneys, furnaces, gas boilers, heat exchangers, light bulbs)
- household & appliances (ovens (inserts), stoves, barbecues)
