Gorilla takes epoxy to a new level-the Gorilla Tough level. With its superior solvent and water resistance, Gorilla Epoxy adhesive is incredibly strong and durable for household and automotive repairs alike. The easy-to-use syringe keeps the epoxy resin and hardener separate, so it is easy to dispense and won?t harden over time. The two-part, gap-filling formula easily bonds steel, aluminum, glass, wood, ceramic, tile and most plastics. Plus, it dries in an ideal, crystal-clear finish that makes projects look spotless. Directions: 1. Prepare Your Work Area and the Surface: It is recommended to use Gorilla Epoxy in a well-ventilated area. Prepare the surface: To improve adhesion, roughen smooth surfaces before gluing. Then clean and dry all surfaces to be bonded. 2. Mixing Gorilla Epoxy: Remove the black cap. With tip pointing upward, cut or snap the end from tip of the syringes. With the tip still pointing upward, eliminate air and ensure even dispensing by slowly pushing the plunger until both the resin and the hardener are at the tip. Push the plunger to dispense even amounts of resin and hardener onto a clean, disposable, contained surface. Mix the two parts for about 20 seconds, until the mixture is uniform. 3. Application: After mixing is complete, apply Gorilla Epoxy within 5 minutes. The epoxy mixture will continue to thicken and the bond strength will decrease the longer you wait to apply. 4. Clamping: To reach maximum bond strength, clamp project together and leave undisturbed. Important Cure Times: Set: 5 minutes to apply and position Handling: Allow to cure for 30 minutes undisturbed (no weight or handling) Final Cure: Allow 24 hours for load-bearing weight Storage: To close, pull plunger slightly back. Wipe tip clean with dry cloth and align notch on tip and cap. Close tightly. Click on the Gorilla link at the top of this page to see more fine products from the Gorilla Glue Company.
