One-component RTV rubbers
With one-component RTV silicone rubber compounds, work can begin as soon as the product is ejected from its tube or cartridge. These products become elastic rubbers after curing, and adhere well to almost all materials as they cure. These properties make one-component RTV silicone rubbers suitable for a wide range of applications.
• Electrical properties
They have outstanding electrical properties, in terms of volume resistivity and ability to withstand high voltage.
• Heat and cold resistance
They can be used over a wide temperature range (-40°C to +180°C).
• Shock resistance
The cured rubbers have excellent rubber elasticity and absorb vibration and shock.
• Weather resistance
One-component RTV rubbers exhibit almost no deterioration when exposed to the outdoor elements for long periods, because they have outstanding resistance to UV rays, ozone, and moisture.
• Workability
These products are easy to use, because they can be ejected from their tubes (or other containers) and used immediately.
