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 epoxy and polyurethane materials.

 

Air & HEPA Filters

Cost-effective epoxy resin and polyurethane filter 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.

 

Benefits of Epic Resins Filtration Materials: 

  • 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
