Structural epoxy adhesive FAQs:
Applications, Materials, and Technical Support
What materials are compatible with Megapoxy’s structural repair epoxy adhesives?
Megapoxy’s Strengthen & Repair adhesives bond securely to most common construction and industrial materials – including concrete, masonry, natural stone, metal, timber and engineered substrates. They’re purpose-built for high-performance applications, whether that’s repairing cracks and spalling or reinforcing and anchoring structural elements in tanks, pipes, slabs, beams and bridge components.
What curing conditions are recommended for optimal performance?
Megapoxy structural epoxies cure effectively between 10–35°C. Work and cure times are temperature-dependent, and full mechanical strength is typically reached within 24–72 hours. For faster or slower curing, select the specific product grade or use temperature management strategies.
Are these epoxies safe for potable water applications?
Certain Megapoxy grades are potable-water safe and certified for direct contact. Always verify product specifications before using in drinking water tanks or pipelines.
Can I colour Megapoxy adhesives?
Yes, most Megapoxy adhesives can be pigmented using our specially formulated epoxy pigments for colour matching or aesthetic purposes.
Do you provide technical support and project guidance?
Megapoxy provides full technical support, including application guidance, specification advice, and troubleshooting assistance to ensure optimal repair and strengthening results.
