United Resin has an extensive selection of epoxy resin systems for the electronics industry, several of which are UL approved (flame retardant). We have both filled and unfilled systems in a range of viscosities.
Our products are used for potting, encapsulating, and casting a wide range of electronic assembly components, including coils, transformers, circuit boards, magnetic components, marine sonar, noise interference filters and surge protectors.
Specialty systems include:
- COB and SMT materials used for applications on circuit boards
- Fiber optics
- Filled and unfilled systems
- Light emitting diodes
- One-component and two-component epoxy resin systems that withstand vibration and shock
- Filled and unfilled systems that bond well to PTFE, nylon, acetal, ceramics, Delrin, PEEK, stainless steel and many other hard to bond to substrates
- Quick set epoxy systems that set in as fast as 45 seconds and systems where curing time can be accelerated with heat
- High temperature epoxy systems
- High strength systems
- Adaptable systems, including mix ratio options and viscosities ranging from liquid to paste
- Chemically resistant epoxy systems
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.
