Permanently elastic silicone sealing compounds for engine and bodywork, brief temperature resistance of 300°C

Cold-vulcanising silicone rubber

Bridges larger unevenness

Reliable at sealing, even after withstanding years of vibrations

Excellent adhesion and chemical resistance

Does not run or pull threads

Skin formation after just a few minutes, vulcanisation rate approx. 1.5 mm/day

Notice

Liquid sealants must only be used in combination with the original seal

Sufficient air exchange should be ensured during the curing phase

The curing time is extended due to a higher coating thickness

Description

Chemical protective glove chloroprene

Description:

Permeation level: 3

Heavy-duty design

Permeation is the process by which a chemical moves through the material of a protective glove on a molecular level. The time from the initial contact between the chemical and the glove to the permeation of the material is the breakthrough time.

Important information:

The information given is based on experience and laboratory conditions and is designed as a guide. However, the actual suitability of a glove depends on the individual conditions of its use and must be confirmed by an appropriate test under operational conditions. Given the variety of materials and chemicals used, the possibility of incompatibility or usage problems for the wearer cannot be excluded in individual cases. We would be happy to advise you about optimum solutions.
