Two-component liquid rubbersfor electric and electronic applications

Two-component liquid silicone rubber compounds cure by adding a specified amount of a curing agent to the base compound. Like one-component liquid silicone rubbers, two-component liquid silicone rubbers have outstanding electrical properties and resistance to heat and cold, while also offering improved deep-section curability and storage stability.


Properties identical to those of one-component liquid silicone rubbers

Electrical properties, heat and cold resistance, impact resistance, weatherability, curing characteristics, etc.

Deep-section curability

The curing reaction proceeds uniformly at the surface and internally, regardless of rubber thickness.

Adjustability of cure speed

Cure time can be adjusted by changing the type or quantity of curing agent, or by heating.


The base compound and curing agent are stored separately, so the product will not become unusable due to curing during storage. Two-component liquid silicone rubbers can be stored for long periods.
