EpoxyPro EP1550B

Special Clear 2:1 Marine Wet Lay-Up Hardener

EpoxyPro EP1550B is a special clear marine epoxy hardener developed for boatbuilding, fibreglass laminating and composite marine construction where maximum clarity and finish quality are required. Formulated from a low-colour, low-viscosity cycloaliphatic polyamine, it delivers excellent fibre wet-out, superior adhesion and high-gloss laminates with outstanding moisture resistance and durability. When combined with EpoxyPro EP1550B, the system is ideal for clear fibreglass sheathing, bright-finished timber boats, carbon fibre components and premium marine composite applications where a crystal-clear finish is essential. The hardener is also free from amine blush, helping produce cleaner laminates and reducing surface preparation between coats.

Why Choose EpoxyPro EP1550B Special Clear Hardener?

Exceptional Optical Clarity

EP1550B is a premium special clear epoxy hardener engineered for marine and composite laminating applications where appearance is just as important as strength. Its advanced formulation produces exceptionally clear laminates with excellent colour stability, making it ideal for bright-finished timber, exposed carbon fibre, decorative composites and clear-coated marine components.

Superior Fibre Wet-Out

The low-viscosity curing system rapidly penetrates fibreglass, carbon fibre, aramid (Kevlar®) and other reinforcement fabrics, providing excellent resin flow, complete fibre saturation and outstanding laminate consolidation with minimal air entrapment.

Excellent Surface Finish

EP1550B produces a smooth, high-gloss finish with excellent clarity and reduced surface blush, helping minimise sanding and finishing while enhancing the cosmetic appearance of composite parts.

Versatile Processing

Suitable for wet lay-up, vacuum bagging, resin infusion, resin transfer moulding (RTM), contact pressure moulding and filament winding, EP1550B delivers reliable performance across a wide range of professional marine and composite manufacturing applications.

High Structural Performance

When combined with EpoxyPro EP1510A Marine Epoxy Resin, the system develops excellent adhesion, high mechanical strength, and outstanding moisture resistance while maintaining superior clarity and long-term durability.

Premium Marine Durability

Designed for demanding marine environments, EP1550B offers excellent water resistance, colour stability and long-term performance. It is an excellent choice for bright-finished timber boats, exposed carbon fibre components, decorative laminates and premium composite construction.
