Sealant High Temperature Resistant Silicone WEICON 10000432 HT 300 LOCTITE 5399
WEICON HT 300 is red, high-temperature-resistant (+300 °C/+572 °F), free of solvents, strong, and acetoxy-curing. It is resistant to weathering, ageing and chemicals and is extremely elastic (breaking elongation of approx. 300%). The product is particularly suitable for heat-exposed bonds and seals and adheres very well to steel, aluminium, glass, ceramics and many other materials. The adhesive and sealant can be used in industrial furnaces, flue gas systems, heating installations, exhaust gas routing, heating cabinets and in many additional areas.
LOCTITE® SI 5399 is a red, thixotropic, room temperature curing acetoxy silicone paste, generally used for sealing applications but also suitable for bonding and high-temperature applications. It is primarily used in industrial adhesive and sealing applications, in heating technology, in industrial ovens, in electrical household appliances, and in industrial heating systems where temperatures up to +350 °C (+662 °F) occur.
