Sikaflex-227 is a 1-component, fast-curing, fast-skinning polyurethane based, elastomeric adhesive/sealant. It is a moisture-cured, non-sag system. Sikaflex-227 provides a permanently elastic bond to fasten materials which have dissimilar coefficients of expansion.

Waterproofing exterior lap seams in many applications, including truck trailers, RV's, metal roofs, window perimeters, grain bins and HVAC units. Waterproofing rivet seams. Sealing of exposed and concealed joints of aluminum, steel, coated metals, wood, roof rails, and door hinges in transport equipment.
