Epoxite - EPG 103/EH 301

Epoxite EPG 103/ EH 301 – Lamination Grade Epoxy System

High-performance epoxy resin system for FRP laminates, composites, and structural reinforcements.

Epoxite 103 (Resin) combined with EH 301 (Hardener) is a low-viscosity, two-component epoxy system developed for laminating fibreglass, carbon fibre, and other reinforcements in marine, automotive, tooling, and industrial composite applications.

This unfilled system delivers excellent wet-out, strong adhesion, and superior mechanical properties when fully cured. The formulation is engineered to offer balanced pot life and cure time suitable for hand lay-up, vacuum bagging, and other composite manufacturing techniques.

Its a clear finish with a stable curing behaviour make it ideal for applications demanding optical clarity and dimensional stability.

Key Features

• Excellent wetting properties for glass and carbon fabrics

• Low viscosity – easy to apply by brush, roller, or infusion

• Air release for bubble-free laminates

• Long working time allows for complex layups

• Cures to a rigid, non-brittle matrix with high dimensional stability

• Compatible with most fibre reinforcement materials
  
  

Typical Applications

• FRP lamination (hand lay-up and vacuum bagging)

• Boat hulls, deck panels, and internal structures

• Automotive composite panels

• Sporting goods and industrial components

• Tooling face coats for molds
  
  

Recommended Processing Conditions
