Description
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.
