Two-component RTV rubbers
(for electric and electronic applications)A two-component RTV silicone rubber compounds cures by adding a specified amount of a curing agent to the base compound. Like one-component RTV rubbers, two-component RTV 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 RTV rubbers
Electrical properties, heat and cold resistance, shock resistance, weather resistance, 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 rubbers can be stored for long periods.
