Two-component RTV rubbers
for electric and electronic applications

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

Features

Properties identical to those of one-component RTV 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.

Storability

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