Silcoset 158 Heat‑Resistant Silicone Oven Door Sealant – 75 ml
A single‑component RTV silicone that cures on contact with ambient moisture, Silcoset 158 delivers a flexible, durable seal that stands up to the extreme temperatures inside an oven. Perfect for repairing oven doors, cooker gaskets or any high‑heat kitchen appliance where a reliable seal is essential.
Why it works
– Broad temperature range: stays flexible from ‑60 °C to +300 °C, so it won’t crack when the oven heats up or cools down.
– Strong adhesion: bonds to glass, metal, glazed ceramics and many other substrates without the need for primers.
– Chemical & weather resistance: resists ozone, UV, oil, solvents and ageing – ideal for the harsh environment of a kitchen.
– Electrical insulation: provides safe insulation for any nearby wiring or components.
Key specifications
– Tack‑free time: ~4 minutes
– Skin‑over time: 3 mm depth in about 7 hours (depends on humidity and temperature)
– Compliance: Meets MOD‑AFS 1540B and Rolls‑Royce MSRR 9146 standards
Whether you’re sealing a cracked oven door gasket or reinforcing a new cooker installation, Silcoset 158 offers a quick‑dry, long‑lasting solution that keeps heat where it belongs and prevents leaks. Its ready‑to‑use tube makes application easy—just squeeze, smooth, and let the moisture in the air finish the cure. Ideal for DIY enthusiasts and professional technicians alike.
