Filter Media Bonding and End Cap Sealing for Your Application

We engineer epoxy and polyurethane adhesives around your filter media, housing materials, operating fluids, and manufacturing process, delivering bonds designed for long-term filtration performance instead of relying on a stock product.

Why Filter Manufacturers Choose Innovative Resin Systems

The three advantages below come from decades of formulating bonding and sealing systems for demanding industrial filtration products.

Multi-Chemistry Formulation Under One Roof

We formulate REZ-CURE heat-cure epoxy systems, ambient- and elevated-cure epoxies, and ambient-cure polyurethanes in-house, matching the chemistry to your media, process, and performance requirements.

Performance That Holds Up

Our formulations resist water and aviation fuel while maintaining performance against solvents, phosphate esters, hydraulic oils, and other process fluids your filters encounter.

Work Directly With the Formulator

When testing uncovers a change, you don’t wait for messages to move through layers of support. You work directly with the chemist behind your formulation, with each iteration backed by the ISO 9001 and UL documentation your qualification process expects.

Application Areas

Adhesives Engineered for Industrial Air Filtration and Beyond

From engine air intake systems to industrial gas and liquid filtration, our adhesives bond media, seal seams, and mold end caps across a wide range of filtration applications.

Air and Gas Filter Media Bonding

Pleated and panel filter media must remain securely bonded under continuous airflow and pressure differentials. Our epoxy and urethane adhesives bond media to metal, stainless steel, and plastic end caps and lock the pleats in place for the life of the filter.

Engine and Cabin Air Filtration

Intake and cabin filters face heat, vibration, and constant dust. Our adhesives form a durable seal between media and frame, keeping unfiltered air from bypassing the element.

Liquid and Water Filter Assembly

Industrial liquid filtration cartridges and pleated elements rely on seals that resist swelling and pressure. Our systems bond media to end caps and pot cartridges, preventing bypass flow.

Fuel and Aviation Filtration

Fuel filters demand adhesives that stay intact in direct contact with aviation fuel and hydrocarbons. Our epoxy systems keep their bond and mechanical strength where fuel exposure degrades lesser products.

Coolant and Hydraulic Filtration

Industrial coolant filtration and hydraulic elements run in oil, water-glycol, and additive-heavy fluids. Our formulations resist these fluids and keep the media-to-end-cap seal tight under sustained pressure.

End Cap Molding and Potting

Some elements need the end cap formed directly on the media rather than bonded to a pre-made cap. Our pourable systems mold the end cap, encapsulate the media, and hermetically seal the assembly in a single operation.

Frequently Asked Questions

Find answers to common questions about our industrial filtration adhesives and sealing systems, from choosing a resin to matching your service fluids.
What are industrial filtration adhesives used for?

They bond filter media to metal, stainless steel, and plastic end caps, mold end caps directly onto the media, and hermetically seal the element, directing flow through the media while withstanding the operating environment.

How do I choose between epoxy and polyurethane systems?

The right chemistry depends on your fluid, temperature, and flexibility needs. Epoxy systems offer high strength and chemical resistance, while polyurethane systems add flexibility and impact resistance. We help identify the chemistry that best fits your filter design, operating environment, and production process.

Which fluids can your adhesives withstand?

Our systems resist water and aviation fuel and stand up well to solvents, phosphate esters, hydraulic oils, and other reagents. We match the formulation to the exact fluids your filters will face.

Can you bond media to metal, stainless steel, and plastic end caps?

Yes. We formulate adhesives that join filter media to each of these end cap materials, and that mold end caps directly where your design calls for it, giving you one sealed and structurally sound assembly.

Do you formulate custom industrial filtration solutions?

Yes. We build epoxy and polyurethane systems around your media, end cap material, operating fluid, cure profile, and production process rather than fitting your filter to an off-the-shelf product.

Do you support qualification and production scaling?

Yes. Our chemists work with you from formulation through validation and production, providing technical guidance, ISO 9001 quality systems, UL-recognized formulations where applicable, and the supporting documentation needed for qualification and scalability.
