Epoxy Adhesive FAQ
Q: What is the maximum gap Epoxy Adhesive can fill?
A: Our standard Epoxy Adhesive effectively bridges gaps up to 3mm (1/8"). For larger gaps (up to 12mm/0.5"), use our specialized gap-filling formula. The bond strength decreases with increasing gap size, so mechanical fasteners are recommended for structural applications with gaps exceeding 6mm.
Q: Can Epoxy Adhesive withstand outdoor conditions?
A: Yes, our premium Epoxy Adhesive is UV-resistant and waterproof when fully cured. It maintains performance in temperatures from -40°C to 150°C and resists most chemicals, including oils and mild acids. For constant saltwater exposure, we recommend our marine-grade epoxy variant with enhanced corrosion protection.
Application Guide
- Prepare surfaces: Clean, dry, and roughen smooth surfaces
- Mix components: Equal parts resin and hardener for 2 minutes
- Apply: Spread evenly on one or both surfaces
- Clamp: Apply light pressure (1-2 psi) for 1-2 hours
- Cure: Allow 24 hours before subjecting to stress

Epoxy Adhesive FAQ (Continued)
Q: How do I remove cured Epoxy Adhesive?
A: Fully cured epoxy requires mechanical removal (sanding, scraping) or chemical strippers containing methylene chloride. For uncured epoxy, use acetone or denatured alcohol immediately. Always test cleaners on inconspicuous areas first. Heat guns (below 150°C) can soften epoxy for easier removal but may damage some substrates.
