TDS Deck Sealant is a one-part, paste-like neutral cure system which, 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.
SIS440 was strictly developed by TDS for teak deck seams. It is a well tested and proven product 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.
