Silverthane SA-2100 Polyurethane Adhesive/Sealant by System Three

Adhesive Use:

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.

Sealant Use:

As a sealant the purpose of SA-2100 is to keep water from passing between two attached surfaces. Simple bonding as described above accomplishes this with the caveat that it may be impossible to get the two materials apart because of the tenacity of the bond. Two things are important here: First, the SA-2100 must be thick enough so that the fasteners may be tightened to affect a seal if leaking occurs in the future. Second, a suitable “mold release” must be used so that SA-2100 does not stick where it is not wanted.
