Product Overview
Nearly as strong as Sikaflex 291 and slightly more flexible, Sikaflex 291 LOT takes longer to become tack-free, allowing for a longer working time. Perfect for general sealing when extended work time is needed, e.g. where lots of adjusting or fitting is required. Sika 291 LOT is an economical, polyurethane based sealant and light duty adhesive. This is an all-purpose product used for general sealing applications such as deck hardware and equipment. It is resistant to weathering, seawater and ultra-violet radiation. Sika 291's permanent elasticity and medium strength, make for relatively easy disassembly, should that be necessary; use razor wire as a tool. For similar performance with non-yellowing benefit use Skiflex 521 UV (very good) or 295 UV (best), but note shorter work time.
Excellent adhesion to gelcoat, fiberglass, metal and wood
Use above or below the waterline
Low viscosity - easy to gun
Due to its high joint movement capacity, 291LOT is particularly suitable for large joints and gap filling
NSF & USDA approved for potable water
Paintable, sandable, tools with soapy water, and skins over slowly (3 - 5 hours)
Use soapy water (never alcohol) to tool polyurethane sealants or adhesives
Bonds very well to itself and other cured polyurethanes
