Self-Leveling Silicone Sealant For Hot Pipe Applications

DuraSil SL Self-Leveling Silicone Sealant

DuraSil SL is an oxime (neutral) cure silicone sealant designed for use in pitch pans and warranted ChemCurb penetration seals. DuraSil SL is suitable for hot pipe applications up to 400°F (204°C). DuraSil SL’s low durometer and resilient "elastomeric" properties accommodate greater movement in penetration seals than typical urethane sealants. DuraSil SL is solvent free, contains no isocyanates and will not shrink upon curing. DuraSil SL can be used effectively in wet or dry climate conditions and at low temperatures down to 32°F (0°C).
