Adhesives and Potting Compounds for Filter Manufacturing

Since 1958, Epic Resins has been manufacturing quality resin compounds for a wide range of industries. We formulate compounds for applications such as:


Pool and Spa Filters

Full line of chemically-resistant polyurethane end cap materials for the spa, pool, and submersible pump industries.


Air & HEPA Filters

Cost-effective epoxy resin and polyurethane filter adhesives, potting compounds and end cap materials that withstand shock, vibration and temperature extremes.


Oil & Gas Filters

Chemically-resistant epoxy resins and polyurethanes for use in filters designed to separate contaminants present in oil, gas, greases, and coolants. We offer an extensive line of products for molded end-caps, potting and casting materials, seam sealing and end caps adhesives.

Epoxy Resin and Polyurethane Filtration Properties

We can adapt any of our epoxy resins or polyurethanes to meet the specifications of your industrial filtration application. Our products feature modifiable properties, including electrical, chemical and heat resistance, and adhesion rates. We add thermosetting polymers to our filtration adhesives to ensure chemically-resistant resin combinations are available. Thermosetting polymers allow our products to maintain adhesive and bonding functionality while exposed to chemicals in a high-temperature setting. Thermoset is set once cured, meaning the chemical reaction has occurred and cannot be altered by outside forces. Our epoxy and polyurethane filtration adhesives remain secure in any circumstances.

Benefits of Chemically Resistant Resins: 

  • Reduces exposure and flammability, as compared to powder coatings
  • Fast curing time: bonds in as little as 5 minutes, depending on the curing temperature
  • Resistant to thermal shock: -40°F to 400°F (-40°C to 204°C)
  • Low water absorption with favorable thermal conductivity
  • Can adhere to metals, glass, wood, stone, and some plastics
  • Works in elevated temperatures
  • Works effectively with coolants, gas, lubricants, and oils
