WEICON Silicone HT 300 HIGH Temperature Sealent

High-temperature-resistant | acetoxy-curing

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.

Surface pre-treatment

Surfaces must be clean and free of grease. Many surface soilings, such as oil, grease, dust and dirt can be removed with WEICON

Surface Cleaner. For heavily soiled metal surfaces, we recommend Cleaner Spray S; for removing old colour residues or adhesive residues, WEICON Sealant and Adhesive Remover is ideal. Most materials can be bonded to and among each other. For certain materials or special requirements, we recommend the use of a bonding agent (primer). Mechanical surface pre-treatment e.g. by grinding or sanding can also improve the adhesion considerably.

Processing

Processing Cartridge gun for 310 ml cartridges, compressed air gun, we recommend a version with piston rod (WEICON Compressed Air Cartridge Gun), automatic dosing systems. Squeeze out by hand, close tube again immediately after use, opened tubes should be used up as quickly as possible Joining the components In order to guarantee and ideal wetting, the bonding parts need to be joined, before the adhesive skins over (skin-over time).
