Heat Resistant Silicone
High Temperature Sealant
Temperature resistance up to 300°C
UV resistant and waterproof silicone sealant that has been designed for high temperature use. Once cured HT30 will resist temperatures of 250°C permanently and up to 300°C for short periods.
HT30 is a ready to use, one component, acetic curing silicone sealant that does not loose it's sealing properties under extreme conditions. So it's suited to sealing joints that are exposed to high temperatures. Typical uses include: industrial ovens, domestic appliances, heating systems, high temperature machinery and car engine compartments.
HT30 offers primer less adhesion to Enamel and Ceramic tiles, Glass, Epoxy paint and Polyester as well as a range of other common materials. With a primer HT30 can be used on even more surfaces, like Polyamides, ABS and Metals.

Limitations
Not suitable for use with aquarium building or within 1 metre of wood burning stove flues. HT30 can cause stains around joints on marble, sandstone and other extremely absorbent substrates if they are not treated carefully with a primer. During the curing process small quantities of acted acid are released which could attack certain kinds of metal and alkaline substrates. HT30 cannot be over painted, therefore substrates to be painted must be kept free of sealant.
