Frequently Asked Questions
Q: What materials can this two-component epoxy adhesive bond?
A: This high-strength epoxy adhesive is designed primarily for metal, iron, steel, and cast metal surfaces. It also bonds well to aluminium, ceramics, stone, and many rigid plastics, making it a versatile repair solution for home, automotive, and industrial applications.
Q: How long does the epoxy take to cure?
A: Working and cure time depends on ambient temperature. At room temperature (around 20–25°C), the adhesive typically achieves an initial set within 30–60 minutes and reaches full strength after 24 hours. Warmer conditions speed up curing; cooler conditions slow it down.
Q: Can I sand, drill, or paint over the cured epoxy?
A: Yes. Once fully cured, this two-component epoxy is fully machinable — it can be drilled, filed, sanded smooth, and painted over to match the surrounding surface, making it ideal for professional-finish repairs.
Q: How much adhesive is included, and is it enough for multiple repairs?
A: Each pack contains 100g of two-component epoxy adhesive (combining both parts), which is sufficient for multiple small-to-medium repairs. The generous quantity makes it great to keep on hand in any workshop or garage.
