Product Category: 
Silicons
Stock: 
36.00
Content Size: 
310 
Milli Liter (ml)
WEICON HT 300 adhesive and sealant is red, high-temperature resistant (+300°C/+572°F), free of solvents, strong, and has acetatecross-linking properties. It is resistant to weathering, ageing and chemicals and is extremely elastic (breaking elongation of approx. 500%).

HT 300 is particularly suitable for heat-exposed bonds and seals and adheres very well to steel, aluminium, glass, ceramics and many additional materials.

HT 300 can be used in industrial furnaces, flue gas systems, heating installations, exhaust gas routing, heating cabinets and in many additional areas.
