What Entropy Resins does

Entropy Resins is a specialty chemical brand and DBA of Gougeon Brothers Inc., manufacturing biobased epoxy resins at the parent's Bay City, Michigan facility. Its proprietary Super Sap formulation platform replaces petroleum-derived feedstocks with plant-based ingredients, yielding products that carry USDA BioPreferred certification and 20-30% verified biobased carbon content (ASTM D6866). The portfolio centers on Clear Casting Epoxy (CCR, with Fast and Slow hardeners), Clear Laminating Epoxy (CLR), Compression Molding Epoxy (CPM), and the newly launched BIOinfusion™ system for vacuum infusion and closed-mold composites, supplemented by color tints, metallic pigments, dispensing pumps, and an online LCA Calculator developed with Long Trail Sustainability.

The company sells primarily through a direct-to-consumer e-commerce storefront (entropyresins.com/shop) backed by phone and email support, complemented by regional distributors in the UK (Gael Force Marine), Spain (Hegardt), and Turkey (Etap Marine). End-customers are predominantly small-business artisans and individual makers across four verticals: surfboard and board manufacturing, custom woodworking and furniture (including river tables and luthiery), resin art and casting, and commercial coating applications. Pricing is unit-based with publicly listed kit sizes from 1.5 quarts to 15 gallons, and there is no subscription or recurring model. The company differentiates on quantified sustainability — cradle-to-grave LCA, USDA certification, and 1% for the Planet membership — rather than on price, and holds ISO 9001:2015 certification through Gougeon Brothers Inc.

Products and services

• CCR — Clear Casting Epoxy Resin Water-clear, low-viscosity epoxy system for casting, embedding, and high-build coating applications. Available with Fast Cure (CCF, 90-min pot life) and Slow Cure (CCS, 360-min pot life) hardeners. 30% biobased content, USDA BioPreferred certified, low VOC (0.07–0.08 lbs/gal).
• CCF — Clear Casting Fast Hardener Fast hardener component for the CCR Clear Casting Epoxy system, providing a 90-minute pot life and 24-hour tack-free time at 95°F for low-volume castings under 1/2 inch thickness.
• CCS — Clear Casting Slow Hardener Slow hardener component for the CCR Clear Casting Epoxy system, providing a 360-minute pot life and 72-hour tack-free time for mass castings and pours up to 1 inch deep.
• CLR — Clear Laminating Epoxy Clear laminating epoxy used for surfboard construction, repair, and composite glassing/lamination, valued for clarity, hardness, workability, and UV resistance.
• CPM — Compression Molding Epoxy Epoxy formulation designed for compression molding processes, requiring a minimum elevated cure temperature of 150°F (65°C) for proper cure and optimal mechanical properties.
• BIOinfusion™ Innovative epoxy system designed specifically for vacuum infusion and other closed-mold processes, representing the next generation of sustainable composite infusion resins from Entropy Resins.
• Vivid Colour Tints Powder and liquid pigments for tinting epoxy castings, producing vibrant colors that bring out hues in wood and add vibrancy to pieces.
• Shimmering Metallics Kit Metallic powder kit for creating sparkling effects and designs in epoxy castings.
• Dispensing Pumps Two-pump reusable system that dispenses the correct 2:1 by volume ratio of resin to hardener, simplifying mixing and reducing cure-related errors.

Direct peers

• TotalBoat: Marine and DIY-focused epoxy and coatings brand sold direct-to-consumer and through Jamestown Distributors. Comparable SMB/prosumer sales motion and overlapping surfboard/woodworking clientele.
• ArtResin: Epoxy brand focused on artists, resin art, and craft coatings. Comparable consumer/SMB customer base and direct-to-consumer e-commerce distribution model, even though its product is not differentiated by biobased content.
• Sicomin: French formulator of epoxy systems for marine, sports, and composite applications, with a dedicated GreenPoxy bio-based product line. Comparable in offering biobased epoxies for both artisan and higher-volume composite customers, with deeper presence in European industrial channels.
• EcoPoxy: Canadian manufacturer of biobased epoxy resins marketed to woodworkers, artists, and composites fabricators. Directly comparable product positioning, sustainability-driven GTM, and overlapping customer segments make it the closest analog to Entropy Resins.
• Resoltech: French epoxy systems manufacturer with biobased and clear-coating lines for marine and composite applications. Comparable product breadth and European distribution overlap with Entropy's international push.
• System Three Resins: US manufacturer of specialty epoxy and polyurethane systems for marine, woodworking, and art (e.g., MirrorCoat). Overlapping customer cohorts in surfboard, woodworking, and coatings segments, with a longer track record but less biobased differentiation.
• MAS Epoxies: US specialty epoxy formulator serving art, wood, and small-composite customers. Comparable niche premium positioning and small-maker customer focus, though without a sustainability-led proposition.
• East Coast Resin: Art and craft epoxy brand competing for the same artist and prosumer casting/laminating segment that Entropy serves with its CCR and CLR lines.

Broad incumbents

• Hexion: Global incumbent epoxy resin producer serving construction, composites, electronics, and coatings. Comparable underlying chemistry, but at vastly broader scale and with a portfolio rather than a single sustainability-focused brand.
• Olin Corporation (D.E.R. Epoxy): Large diversified chemical producer with a major liquid epoxy resin franchise (D.E.R.). Comparable product category and raw-material overlap, but operating at petrochemical scale with commodity distribution channels.
