3 Benefits of Using Polyurethane Potting Compounds for Pool Filters


The obvious first requisite for any element to your filtration manufacturing is its ability to resist water. Constant exposure to water will not reduce the effectiveness of our potting compounds designed for pool and spa filtration. Resins such as our Epic S7364 are resistant to water, allowing continuous high-level performance for your filter.

Our manufactured antimicrobial pool filter potting compounds will provide complete satisfaction in keeping you worry-free.


In order to maintain a clean pool or spa, chemicals are needed to eliminate all contaminants. Harsh cleaners like pH increaser, pH decreaser, chlorine, and quaternary ammonia are just a few of the chemicals used to keep water sanitized. Epic Resins provides 2-component potting compounds to prevent corrosion from pool cleaning substances while continuously stopping the growth of bacteria and fungus.

Below are a few of the many polyurethane potting compounds Epic Resins produces for pool and spa filtration:

Hot tubs, spas, and temperature-controlled pools require different types of heaters, such as electric, natural gas, propane, or heat pumps. Pool heating is great for relaxation and therapy, but if a filter can’t handle high temperatures, it will warp -- causing filter failure.

Despite the changing temperature of the water, Epic Resins’ heat-resistant potting compounds enable spa filters to ward off unwanted filth in your pool/spa without being affected by pool heaters.

Potting compounds are essential for any manufacturer designing pool filter cartridges to rival those made by competitors. Epic Resins has the ability to custom formulate polyurethane potting compounds PERFECT for your filtration needs. We’ve done the same for manufacturers in many industries including Automotive, LED lighting, and Telecommunications.
