FIBREGLASS & COMPOSITE SYSTEMS

Epoxy Resin Systems

High-performance laminating, bonding and coating resin — mixed at a fixed resin:hardener ratio. No MEKP. For structural, marine and composite work.

RESIN CALCULATOR

Epoxy Resin Ratio Calculator

Epoxy uses a fixed resin:hardener ratio — not MEKP catalyst. Enter your resin amount to calculate the correct hardener.

⚠ Not MEKP — never add MEKP catalyst to an epoxy resin system. Epoxy and polyester chemistry are incompatible; mixing causes failure.

General guidance only. Always follow the resin manufacturer’s Technical Data Sheet for the exact ratio and pot life.

Complete the laminate

Don't forget these essentials

Resin is one part of the laminate. The right catalyst, reinforcement and application tools all matter to get the finish right.

Frequently Asked Questions

What are epoxy resin systems used for?
Epoxy resin systems are used for bonding, laminating, coating and structural repairs in marine, construction and composite fabrication applications.
What is the difference between epoxy and polyester resin?
Epoxy resin generally provides stronger adhesion, better moisture resistance and improved mechanical performance compared with polyester resin.
What products make up an epoxy resin system?
An epoxy resin system typically consists of a base resin combined with a compatible hardener that controls curing speed and working time.
Can epoxy resin be used with fibreglass cloth?
Yes. Epoxy resin systems are commonly used to wet out fibreglass cloth and reinforcing fabrics in composite laminating applications.
