Epoxy Resin Systems

Don’t Forget These Essentials

Most fibreglass jobs require more than just resin. Make sure you have the right catalyst, reinforcement materials, fillers and application tools to complete your laminating or repair work properly.

Curing

Catalysts & Hardeners

Required to properly cure polyester, vinyl ester and epoxy resin systems.

  • MEKP catalysts
  • Epoxy hardeners
  • Catalyst dispensers
Shop Catalysts
Reinforcement

Fibreglass Mat & Reinforcements

Reinforcement fibres provide the structural strength in composite laminates.

  • Chopped strand mat
  • Woven cloth
  • Composite fabrics
Shop Reinforcements
Modify Resin

Fibreglass Fillers & Additives

Fillers and additives help modify viscosity, strength and finishing performance in resin systems.

  • Q-Cell microspheres
  • Talc fillers
  • Wax and styrene additives
Shop Fillers
Application

Fibreglass Tools & Accessories

Application tools help ensure clean laminating, mixing and reinforcement handling.

  • Laminating rollers
  • Mixing cups
  • Brushes and spreaders

Fibreglass Calculators

Use our fibreglass catalyst ratio calculator, resin quantity calculator, material coverage calculator and roll coverage calculator to estimate laminating materials.

Fibreglass Catalyst Ratio Calculator

Estimate MEKP catalyst required for polyester and vinyl ester resin in weight and volume.

General guidance only. Always follow the resin manufacturer’s Technical Data Sheet and Safety Data Sheet. Resin litre conversions are estimated using an assumed resin density of 1.1 kg/L.

Fibreglass Material Coverage Calculator

Estimate linear metres required from a 1.27 m wide roll, total reinforcement weight and approximate reinforcement volume.

Based on a standard 1.27 m wide fibreglass roll. Estimates do not include overlap, trimming waste or offcuts.

Fibreglass Resin Quantity Calculator

Estimate reinforcement weight, resin quantity in kg and litres, catalyst quantity, and total laminate materials.

General guidance only. Actual resin usage varies based on reinforcement type, technique, overlap, waste and laminate efficiency.

Fibreglass Roll Coverage Calculator

Estimate total area coverage, reinforcement weight and approximate reinforcement volume from a roll length using a 1.27 m roll width.

Based on a fixed fibreglass roll width of 1.27 m. Estimates do not include overlap, trimming waste or unusable offcuts.

Frequently Asked Questions

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