One-component silicone RTV compound.
Gel-like translucent mass.
Chemically neutral, acid-free, therefore, does not corrode the bonded surfaces.
Good adhesion to metals, glass, plastic, wood.
Provides dielectric insulation, prevents aggressive environmental influences.
Retains its mechanical and dielectric properties in wide temperature ranges, from -50C to +250°C.
Not flammable. Waterproof.
Recommended for sealing electronic components on boards, LED lamp housings, car headlights.
Packing: 45 gram tube.

Curing of one-component silicone compounds occurs due to interaction with moisture contained in the air. They cure well at room temperature in the range of relative humidity from 30% to 80%. The level of about 90% of the values of their physical properties is reached within 24 to 72 hours. It is possible to accelerate the curing of the composition with a slight heat, no higher than 60°C.
Silicone sealants should be stored in a sealed container, avoiding contact with air.
When working with adhesive sealant, time is limited for applying silicone mass. Typically, this period is from several minutes to one hour before the formation of a surface film that impairs adhesion.
It is undesirable to use a one-component compound in confined spaces or apply in a thick layer, because in this case, the curing period is significantly increased.
