What resinlab does

ResinLab, LLC is a privately held Wisconsin-based manufacturer of resin-based adhesives and encapsulants, founded in 1988 as Advanced Polymer Concepts and rebranded to ResinLab in 2000. The company operates a 106,000 sq. ft. state-of-the-art facility in Germantown, WI, co-located with sister companies KitPackers (custom packaging) and Ellsworth Adhesives (distribution and e-commerce). ResinLab's core technology is the formulation of two-component polymer systems across epoxy, urethane, silicone, methacrylate, cyanoacrylate, and anaerobic chemistries, with precision mix ratios and chemistries tailored for room-temperature or heat cure. The catalog spans ten adhesive lines (including FDA-compliant, medical device, thermally conductive, electrically conductive, edge-fill syntactic for aerospace, and polyurethane) and four encapsulant lines (epoxy, thermally conductive, UL-recognized, and urethane), with over 200 stocked compounds available for stock sale, custom formulation, or modification.

ResinLab generates revenue through five streams: (1) one-time sales of standard and specialty adhesive and encapsulant products in packaging from 50 mL cartridges to 5-gallon pails, (2) custom formulation services, including regulatory reformulation (REACH, RoHS, Prop 65), (3) product modification services for ResinLab and competitor products (3M, Henkel, Dow), (4) toll blending of customer formulations, and (5) custom packaging through KitPackers. Pricing is quote-based and not publicly disclosed; standard SKUs are also available via Ellsworth Adhesives e-commerce. The customer base is B2B and segmented across electronics manufacturing (primary), aerospace, medical device manufacturing, food processing and packaging, and defense and transportation. The product portfolio is supported by regulatory certifications spanning ISO 9001:2015, REACH, RoHS 3, FDA 21 CFR 175.105 and 175.300, ISO 10993-5, GHS, and UL 94V0 component recognition, plus an in-house analytical laboratory for imaging, rheological, thermal, chemical, mechanical, and electrical characterization.

The go-to-market is sales-led, supported by a website-structured technical resource library (epoxy terminology, mixing instructions, REACH/RoHS compliance), an SDS/TDS library, and a quote request funnel. Distribution runs through direct enterprise sales for custom solutions, e-commerce via Ellsworth Adhesives for standard SKUs, and custom packaging via KitPackers. The company does not disclose revenue, headcount, funding, or ownership structure; the careers page redirects to careers.ellsworth.com, indicating operational affiliation with the Ellsworth Adhesives group.
