Speedline Silicone Caulking

Speedline 73-20 RTV Adhesive/Sealant is a one-part, paste-like material that cures to a tough, flexible solid upon moisture/air exposure.

Speedline 73-20 RTV Adhesive/Sealant will not slump under its own weight; it is therefore suitable for applications to overhead or vertical surfaces without detrimental sag, runs or slumps. It provides a strong adhesion to most types of clean PVC (and other plastics), metal, wood, silicone rubber and ceramic surfaces.

Speedline 73-20 RTV Adhesive/Sealant is very resistant to outdoor exposure, moisture, ozone and vibration. It also is resistant to high and low temperatures. It may be applied in sub-zero conditions without loss of its normal properties.

Speedline 73-20 RTV Adhesive/Sealant is available in colors of aluminum and white, as well as clear.
