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.
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
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
Ambient Temperature: 20–30°C (ideal: 23–25°C)
Humidity: < 70% RH for best results
Surface Preparation: Ensure substrates are dry, degreased, and abraded
Can be post-cured at 50–60°C for improved Tg and mechanical strength
