Self-Leveling Polyurethane Sealant

Bostik 955-SL sealant is a one-component, traffic grade polyurethane, self leveling sealant capable of dynamic joint movement totaling 70% of original joint geometry (±35%). The sealant cures to a tough, flexible rubber when exposed to moisture present in the atmosphere.

Bostik 955-SL polyurethane has a pourable consistency. Its physical properties will remain relatively stable over time and in varying weather conditions. Its physical and mechanical properties remain consistent across a broad temperature range, from -40°F to 150°F (-40°C to 66°C).
