United Resin has an extensive and established selection of epoxy resin systems for the electronics industry, several of which are UL approved, meeting potting and encapsulating requirements in a range of conditions. We have both filled and non-filled systems in a variety of viscosities. Our products are used for potting and encapsulating a wide array of electronic assembly components including coils, batteries (including lithium), transformers, circuit boards, magnetic components, marine sonar, noise interference filters and surge protectors. Special systems include Optik-bond, COB and SMT materials used for applications on circuit boards, fiber optics, light emitting diodes and other adhesive applications. All our materials are non-hazardous, REACH/RoHS compliant, and contain no solvents.
We can address your aesthetic considerations with surface finishes in gloss or matte. All our materials are non-hazardous, REACH/RoHS compliant, and contain no solvents.
THE RESINS LISTED BELOW ARE COMBINED WITH THE MOST POPULAR HARDENERS. WE HAVE MANY OTHER HARDENERS, ALLOWING FOR INDIVIDUAL PRODUCT DESIGN.
