HT30 High Temperature Silicone Sealant

Description

Name: HT30 High Temperature Silicone Sealant

A ready-to-use, acetic curing, silicone sealant. Specifically designed for high temperature use, it is UV resistant and weatherproof. After curing HT30 will resists temperatures of 250°C permanently and up to 300°C for short periods.

Features: High Temperature resistance up to 300°C. – Mildew Resistant. – UV resistant and weatherproof .- Sag resistant, non-slumping. – For interior and exterior applications.

Application: Generally used for sealing joints which are exposed to high temperatures, i.e. connections on ovens, heating systems, machines, car bodies (vicinity of engines), etc. It can be applied to glass, ceramic tiles, enamel, epoxy paint and polyester. Moreover, it can also be used with nylon, ABS, metals and polyester in immersion or humid heat. However, a primer may be required in these cases.

Instructions: Preparation: Ensure all surfaces or joints are clean, dry and free from grease, oil or any other contaminants that may hinder adhesion. Primer may be required on certain absorbent surfaces.

Limitations: Not suitable for use within 1 metre of wood burning stove flues. Not suitable for use with aquarium building.

HT30 can also cause stains around joints on marble, sandstone and other
extremely absorbent substrates if they are not treated carefully with a primer. Moreover, it cannot be over painted, therefore substrates to be painted must be kept free of sealant. During the curing process, small quantities of acetic acid are released. These could attack certain kinds of metal but also alkaline substrates.
