Product Description

liquid silicone rubber of condensation type are multicomponent type which are named the RTV(Room Temperature Vulcanizing) as either one can be cured at room temperature. At the time of exposure in the air, gum elastic can be made progressing by crosslinking reaction with moisture.
Depending upon crosslinking type, silicone,s type could be divided into and residual things come

I.Simple Use

Work can be done simply At room temperature, it cures to form rubber state with the humidity in the air without heating or any other special condition.

II.Heatproof/Coldproof

After complete hardening, the adhesion and rubber elasticity can be kept for all continuous exposure in the range of -50oC~200oC.

III.Excellent Electric Characteris

In chemical structure, it shows excellent insulation. It keeps stable electricity even in the change of temperature, humidity, or environment, suitable for insulation or sealing for various electric and

IV.Chemical stability

Silicone sealant show excellent chemical resistance and oil resistance in comparesion with general organic rubber. When it contacts with certain engine oil, it may swell a little but, it is not decomposed not dissolved, it returns initial state when solvent is removed.

V.Excellent Weatherproof

It shows excellent ultraviolet resistance. ozone resistance,and water resistance, which allows to keep original properties semi-permanently at outside use.
