Handling
Mixing: This product requires mixing two components together just prior to the application. Complete mixing is necessary. The temperature of the separate components prior to mixing is not critical, but they should be at room temperature.

Application
Mixing – Bulk: Combine Part A (resin) and Part B (hardener) in the correct ratio and mix thoroughly until the color and consistency are uniform. EPOXI-PATCH® tube kits have been designed so that squeezing EQUAL LENGTH BEADS of Part A and Part B will give proper ratio. Ratios given above can be used for measuring larger amounts. Mixing the adhesive just prior to use is recommended. Heat build-up during or after mixing is normal. Do not mix quantities greater than one as dangerous heat build-up can occur causing uncontrolled decomposition of the mixed adhesive. Mixing smaller quantities will minimize the heat build-up.
Mixing – Cartridges: Place cartridge in proper dispenser. To begin using a new cartridge, remove cartridge cap and dispense a small amount of adhesive, making sure Part a and Part B are extruding. Attach nozzle and dispense approximately 1-2" before applying onto the part being bonded. Partially used cartridges can be stored with mixing nozzle attached. To reuse, remove and discard the old nozzle, attach new nozzle and begin dispensing.
Application:
Bonding surfaces should be clean and dry. For optimum surface preparation, consult Dexter's bulletin "Preparing the Surface for Adhesive Bonding". Once the adhesive is applied, the boned parts should beheld in contact until the part has developed handling strength. It is not necessary to clamp the parts unless movement during curing is likely.
Cure: Complete cure is obtained after 24 hours at room temperature Hysol 615 will achieve handling strength after 10-20 minutes at 77F (note: this can vary with different bond configurations). Hysol 615 can also be fully cured with heat such as: 5-20 minutes at a maximum 150F temperature.
Clean up: It is important to remove excess adhesive from the work area and application equipment before it hardens. Many common solvents and citrus cleaners are suitable for removing uncured adhesive. Consult with your supplier's information pertaining to the safe and proper use of solvents.
