SA-2100 readily bonds to some surfaces with little preparation while in other cases the surface must be properly prepared. Regardless, all surfaces must be clean, dry and free from oil or grease. We urge the user to test the product for adhesion himself for critical applications.

SA-2100 bonds to all woods, stainless steel, mild steel, polycarbonate (Lexan) and plastic laminate countertops, epoxy and polyester resins with no special surface preparation beyond the above.

It bonds poorly to untreated aluminum but extremely well to acid etched (Alumiprep) aluminum. It also bonds to acid etched and chromate surface treated aluminum ( Alodine). Acid etching alone is sufficient as in our tests the SA-2100 ripped off the brown chromate surface.

The bond to untreated polyacetal (Delrin), polystyrene, ABS, PVC, acrylic (Plexiglas), and PETE (polyethylene terephthalate) is fair to poor. The bond to untreated polyethylene and polypropylene is poor. However, the bond is excellent to very good on all these materials once they have been flame treated.

SilverThane SA-2100 is a unique two-part polyurethane sealant-adhesive. It cures overnight in any thickness to a very tough flexible rubber. SA-2100 is bright white and is unaffected by weathering and UV degradation. SA-2100 is a tenacious bonder to many substrates including difficult to bond plastics. It is flexible at temperatures well below zero. Our tests show that it can be painted with most paints without surface preparation
