SIS-440 Teak Deck Caulking
Specifically developed for caulking teak deck seams, this proven sealant can be applied in hot or cold conditions.
For caulking teak deck seams, this proven product can be used in hot or cold climates and needs NO PRIMER. A one-part silane polymer that forms a solid rubber compound, it is better than the polysulfides, polyurethanes and MS polymers. It has the highest rating resistance to UV, excellent resistance to chemicals and excellent temperature stability. A one-part, paste-like neutral cure system, when exposed to moisture in the air, reacts to form a tough, flexible solid rubber compound. The sealant is a thixotropic material, which does not sag during cure, and, when cured, has excellent temperature stability and chemical resistance. Because the sealant is neutral cure, it is non-corrosive to all substrates.
