ENTROPY, the first range of biosourced epoxy resins

Understanding the stakes of sustainable development for future generations and always anxious to offer even more innovative and high-performance products, it is in 2018 that the renowned American company Gougeon Brothers, also manufacturers of WEST SYSTEM, acquired ENTROPY.

Developed using green chemistry (SuperSap technology), ENTROPY resins contain up to 30% organic raw materials. In addition to their composition, their entire life cycle is designed to reduce their environmental impact.

With the exception of the hardener CLX, ENTROPY products do not contain any toxic chemical agents known as CMR.

Resins adapted to woodworking

ENTROPY resins are extremely well suited to woodworking and are ideal for carpenters and artists. Whether for large-scale projects or the manufacture of small objects such as jewellery, ENTROPY resins are excellent for casting as well as for river tables, transparent casts, and more!

Resins suitable for surfboard/paddleboard/gliding sports manufacturing

Resistant to UV rays and totally transparent, ENTROPY resins are also ideal for surfboards, paddleboards, skis and other board sports. They cover a wide range of manufacturing processes, from compression moulding to hot coating, from clear moulding to hand lamination.

ENTROPY (résine bio sourcée)


  • Pigments

    Transparent or metallic color pigments to color your epoxy resins

  • Laminating epoxy

    Highly bio-based epoxy resin for laminates and general coatings. One is a high biobased general purpose laminating resin for laminating, coating and bonding applications of composites. This system features faster speed, low viscosity, fast debubbling, ideal for fibre reinforced composite laminations and coatings. ONE is a USDA certified BIOPreferred® product with a 30% biobase content.

  • Clear casting epoxy resin

    Clear, low viscosity liquid epoxy resin for casting and moulding. CCR is a low-viscosity, water-clear, UV-resistant epoxy system designed specifically for casting and moulding applications. Its low colour and low viscosity allows bubble-free, crystalline casting, ideal for art and leisure applications. This system features two cure rates: slow (CCS) for high density casting resin applications and fast (CCF) for fast casting resin applications for small projects such as resin jewellery and others. CCS is a USDA BioPreferred® certified product with a 30% biobase content.

  • White surfboard/paddle...

    Optical quality providing improved UV resistance for white sailboard and marine epoxy applications. BRT is a general purpose, clear, optical gloss quality, UV resistant laminating resin for white surfboard lamination and hot coating applications. Based on the entropic CLR -Clear Epoxy Resin, BRT can be combined with all CLR Clear hardeners. BRT is a USDA BioPreferred® certified product with a 30% enbiobase content.

  • Anti-UV lamination

    Transparent, UV-stable epoxy resin for laminating, coating and marine applications, compatible with coloured substrates. CLR is a clear, UV resistant, general purpose resin for composite lamination, coatings and adhesive applications. It has an ideal viscosity for a wide range of applications using hand lay-up techniques with rapid curing at room temperature. CLR is a USDA BioPreferred® certified product with a 29% biobase content.

  • Compression moulding

    305 is a compression moulding resin for fast cycle times in heat assisted moulding processes of fibre reinforced composites. Epoxy resin 305 has a high biological content, excellent fibre impregnation qualities and thixotropic characteristics to limit sag in high temperature curing applications. The 305 resin has excellent elongation properties to produce durable but lightweight composite parts.
