Sicomin SR5550 Epoxy Resin (Marine Laminating Resin)

52.31168.42 (ex vat)

  • Excellent, two-part laminating epoxy resin
  • Perfect for marine composites, bonding, laminating and wood protection
  • Excellent adhesion to wood, metal and polyester


This Epoxy Resin has been specially formulated for building marine composites: bonding, laminating and wood protection. It has an excellent adhesion to all type of wood. It has a low viscosity and is crystallisation free. It is excellent for bonding reinforcement materials such as Glass or Carbon onto wood.

Epoxy resin laminates are stronger, stiffer and tougher than an equivalent laminate produced in polyester resin. In addition, higher specification fabrics, such as carbon fibre and Kevlar combine with Epoxy to give high strength to weight structures.

The adhesion of the Epoxy resin to wood, metal and polyester is excellent and it is used as a glue and gap filling adhesive is recommended. Water cannot penetrate through Epoxy and so it is excellent for sheathing wooden boats and canoes with a lightweight fabric, drying to a clear finish.

Sicomin SR5550 Epoxy and SR5505 Hardener are combined at a ratio of 100/29 by weight or 3/1 by volume. This low viscosity mixture with a light amber colour has a working time at 20C of 25 mins, is dry to touch after 2.5 hours and is fully cured after 7 days.
