Overview

About this product

Vinyl Ester Resin is a high performance thermosetting resin engineered for advanced fibreglass laminating and composite manufacturing. It combines the excellent corrosion resistance of epoxy with the easy processing characteristics of polyester resins, making it ideal for demanding environments where chemical resistance, structural strength and long term durability are critical.

This resin system delivers outstanding resistance to acids, solvents and aggressive chemicals while maintaining superior mechanical strength and excellent adhesion to fibreglass reinforcements. Vinyl ester resin is commonly used in marine, industrial, structural and corrosion resistant composite applications where standard polyester resins may not provide sufficient performance.

Iron Link Distributors supplies trade grade fibreglass resins suitable for professional composite fabrication, repair and structural reinforcement applications.

Key Features

  • Excellent chemical resistance for harsh environments
  • High mechanical strength for structural composite parts
  • Superior corrosion resistance compared to polyester resin
  • Excellent adhesion to fibreglass reinforcement materials
  • Improved durability and fatigue resistance in composite structures
  • Good temperature and moisture resistance
  • Suitable for demanding marine and industrial applications

Common Applications

  • Fibreglass laminating and composite fabrication
  • Marine structures and boat building
  • Chemical resistant tanks and vessels
  • Industrial flooring and structural components
  • Corrosion resistant fibreglass pipe and ducting
  • High performance composite repairs

Flammability Warning

Vinyl ester resin is a flammable liquid containing reactive monomers. Keep away from heat, sparks, open flames and other ignition sources. Use only in well ventilated areas and follow all SDS safety recommendations during handling and curing.

Safety Precautions

Use appropriate PPE including chemical resistant gloves, eye protection and respirator protection where required. Avoid inhalation of vapours and prolonged skin contact. Ensure adequate ventilation during application and curing. Refer to the product Safety Data Sheet for full handling, storage and disposal guidance.

How to apply

How to use it

Steps shown for Marine Fibreglass Repair.

  1. Prepare the surface

    30 min

    Grind out the damaged area in a feathered bevel, at least 12:1 ratio (12 mm of bevel for every 1 mm of laminate thickness). Sand with 80-grit, then 120-grit. Clean with acetone and let dry completely.

  2. Mix and apply resin

    60 min

    Mix resin and hardener at the ratio on the TDS (typically 2% by weight). Wet out the prepared surface with a brush, then lay in fibreglass cloth one ply at a time, working from the centre out to remove air. Repeat until the laminate is built up flush with the surrounding surface.
