A one-component addition-curing sealant is a single-component sealing material that cures via an addition reaction using a silicone matrix; it requires no additional curing agent and can cure either when heated or at room temperature.
It combines heat resistance and weather resistance with the flexibility and adhesion of organic materials; the curing process produces no by-products, shrinkage is extremely low, and the material assumes an elastomeric state upon curing, enabling it to operate stably over the long term within a temperature range of –60 °C to 280 °C; Compared with traditional condensation-curing sealants, addition-curing sealants offer superior resistance to high and low temperatures, electrical insulation and ageing resistance; furthermore, they do not release volatile substances, making them environmentally and human-friendly.
The curing rate is significantly affected by temperature; heating can accelerate curing, whilst it can also cure slowly at room temperature. The curing process is not affected by ambient humidity.
