The Universal Epoxy Glue by SuperTite comes in a two-bottle format: Part A (resin) and Part B (hardener), each 4oz (120ml). Mix equal parts 1:1 for a clear, permanent bond that cures strong on metal, glass, plastic, wood, fabric, fiberglass, and more. This bottle format gives you the flexibility to mix only what you need for each project. This is a great option for artists who prefer hand-mixing their epoxy or who work on larger projects where a cartridge system is not practical. The bond is waterproof, impact resistant, and rated at 3,000+ PSI. Use it for crystallizing large surfaces, coating rhinestone work for extra durability, or bonding stones to hard substrates. Includes Part A and Part B bottles (4oz / 120ml each). Mix 1:1 ratio. Cures in approximately 12 hours. UV resistant.
