<br /> Description Sikaflex-1a is a premium-grade,high-performance,moisture-cured, 1-component, polyurethane-based,
<br /> non-sag elastomeric sealant.Meets Federal specification TT-S-00230C,Type II,Class A.Meets ASTM
<br /> C-920,Type S,Grade NS, Class 35,use T, NT,O, M,G, I;Canadian standard CANICGSB 19.13-M87.
<br /> Where to Use ■ Designed for all types of joints where maximum depth of sealant will not exceed 112 in.
<br /> ■ Excellent for small joints and fillets,windows,door frames,reglets,flashing,common roofing detail ap-
<br /> plications,and many construction adhesive applications.
<br /> ■ Suitable for vertical and horizontal joints;readily placeable at 40°F.
<br /> ■ Has many applications as an elastic adhesive between materials with dissimilar coefficients of expansion.
<br /> ■ Submerged conditions,such as canal and reservoir joints.
<br /> Advantages an Eliminates time,effort,and equipment for mixing,filling cartridges,pre-heating or thawing,and cleaning
<br /> of equipment.
<br /> ■ Fast tack-free and final cure times.
<br /> ■ High elasticity-cures to a tough,durable,flexible consistency with exceptional cut and tear-resistance,
<br /> ■ Stress relaxation. n ,r oN
<br /> ■ Excellent adhesion-bonds to most construction materials without a primer.
<br /> ■ Excellent resistance to aging,weathering. t +
<br /> ■ Proven in tough climates around the world.
<br /> ■ Odorless,non-staining.
<br /> ■ Jet fuel resistant.
<br /> ■ Certified to the NSF/ANSI Standard 61 for potable water. `rALT"
