Vulkem 45 SSL Black One-Part Semi-Self Leveling Caulk Polyurethane Exterior Projects Sealant Paintable Tremco Tube - 30 Fl. Oz. 890ml

Vulkem 45SSL is a one-part, moisture-curing, low-modulus polyurethane sealant especially developed for sealing joints in level and/or slightly sloped surfaces. It provides exceptional wear and tear resistance required in high traffic areas. Formulated for use in expansion joints in sidewalks, swimming pool decks, terraces, parking decks, plazas, floors and any other horizontal surfaces with slopes up to 6 percent. Vulkem 45SSL can be applied to damp and green concrete and is suitable for continuous immersion in non-chlorinated water. Vulkem 45SSL has a skin-over time of 5 hours at 75°F at 50% RH. At these conditions, the sealant will be tack-free in 17 hours and continue to cure at a rate of 1/16 per day. At higher temperatures and higher humidity, the sealant will cure faster while at lower temperatures or lower humidity, cure rate will be extended. The cure can be accelerated using minimal amounts of potable water.
