Description:Surtek 3626 is a one-component, moisture-curable,
polyurethane-based, elastic adhesive joint sealant. After curing,
it provides a permanently elastic bond to fasten materials with
different coefficients of expansion. The sealant is solvent free,
environmental friendly.Advantages:1, Good Adhesion to a wide range
of substrates. 2, Cures rapidly to a permanently elastic
consistency with excellent cut and tear resistance. 3, Solvent
free, no odor. 4, Surface paintable with water, oil, and rubber
based coatings. 5, Non-corrosive. 6, Provides shock resistance and
vibration damping. 7, Exhibits high recovery (> 90%), making it
ideal for sealing dynamically moving joints. 8, Weather
resistant.Applications:1, Vehicle bodies and cab construction
including panels, underbody components, and roofing. 2, Front and
rear spoilers, auto trim, moldings, body seams, and welded joints.
3, Waterproofing exterior lap seams in many applications, including
truck trailers, RV's, metal roofs, window perimeters, grain bins
and HVAC units. 4, Waterproofing rivet seams. 5, Sealing of exposed
and concealed joints of aluminum, steel, coated metals, wood, roof
