PSI-326 Fast-Cure Epoxy Repair Compound: Two-component, modified epoxy adhesive. Cures rapidly at room temperature with exceptional adhesion to a wide variety of substrates. No volatile solvents, does not shrink upon curing.

PSI has developed innovative packaging for many purposes. The patented, flexible film Single-Use Mixer Package (SUM PAK^®) holds two components separately, then mixes and dispenses them from a handy film strip for easy mixing and application. SUM PAK achieves perfect or "molecular" mixing in a matter of seconds, something other mixing methods cannot achieve. ("Molecular" mixing is when every molecule "A" is next to a molecule "B".) The reason: an ingenious series of pockets linked by channels that intermingle the two ingredients as they are forced toward the top of the pack, where they emerge, perfectly mixed and ready for easy application.

PSI's Smart Glue^®, a two-component, rubber-modified clear epoxy adhesive is packaged in the SUM PAK to provide a no-mess, single-use, high-hardness epoxy with exceptional adhesion to a wide variety of materials. SUM PAK packaging eliminates the nuisance and mess of conventional 1-to-1 epoxies in a single-use form.
