Polyurethane Adhesives for HEPA Filters

Air-tight bonding is essential for a properly functioning HEPA filtration system. We specialize in formulating durable adhesives to withstand harsh environments. Our polymer products don’t require preheating, and have excellent flow and adhesive qualities. We produce HEPA polyurethane adhesives strong enough to withstand rough handling without cracking or tearing and polyurethanes for seam sealing applications. Producing high-performing HEPA filtration systems is as simple as contacting our polyurethane and epoxy resin experts.

HEPA Filter Applications:

Air & HEPA adhesive and potting compounds:

ToughPleat is a two-component polyurethane series for demanding molded filter end cap applications. This formulation is excellent for filters subjected to constant pulsing and/or pressure drops. High tear resistance prevents the filter from being damaged in the installation or removal process.

Features Include: High tensile strength, High elongation, Excellent tear resistance, Easy to dispense, Reduced WIP time

Epic 0181 is a single component epoxy compound for filter end caps requiring elevated temperature resistance. Epic 0181 bonds to a variety of metals and performs well for short durations up to 300+F. Epic 0181 also offers chemical resistance to most vapors.

Epic S7257 is a two-component polyurethane used for potting filter end caps. The Epic S7257 urethane potting system features a fast set up time and good tear resistance. Epic S7257 has good tensile strength coupled with excellent elongation for a Mid Shore A polyurethane.

Epic S7268 is a two-component reactive polyurethane filter adhesive for use in organic vapor cartridges. S7268 urethane adhesive bonds to both plastic and various filter media. Features quick set-up time and low viscosity for easy workability and exhibits low cure odor.

Epic S7293 is a two-component polyurethane filter adhesive/potting compound for high-temperature applications. Epic S7293 urethane potting features good tear propagation and low weight loss after exposure to 1000 hours @ 275F.

Epic S7421 is a polyurethane casting compound used in filter end cap applications. The S7421 urethane end cap adhesive system features a fast cure and high hardness. Available in various colors.

S7451 is a two-component epoxy adhesive for bonding to a variety of substrates. EPIC S7451 is designed with raw materials meeting one or more of the following parts in CFR Part 21: 175.105, 175.300.

S7463 is a flexible, 4:1 by volume two-component polyurethane end cap adhesive for adhesion to many end cap substrates. Resistant to stress cracking caused by rough handling and/or harsh filtration environment, Epic S7463 is formulated with a fast gel time for quick production cycle times.

S7584 is a two component gel potting compound, designed for use in HEPA filters. It features a convenient 1:1 weight mix ratio as well as a very low mixed viscosity.
