Sikaflex 227, Aluminum Gray, One-Component Sealant, 600 ml Unipac

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.

Use:
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. Sealing and caulking expansion joints and pre-cast concrete panel joints. Suitable substrates are metal primers and paint coating (2-c systems), metals, painted plastics and plastics. Seek manufacturer's advice before using on transparent and pigmented materials that are prone to stress cracking.

Characteristics and Advantages:

  • Adheres to a wide range of substrates, without primer in many cases
  • Exhibits tenacious adhesion to aluminum, FRP, steel, wood, SMC, RIM, prepainted metals, ZINCALUME, Zincgrip, and aluminized steel, without attacking the metal coating
