Automotive Bonding Systems Built to Your Specification

Automotive parts fail in ways few products are built to survive, so the chemistry that protects and holds them can’t be an afterthought. As a specialty formulator, we develop bonding solutions matched to your substrates, load paths, and process line.

Multi-Chemistry Formulation Under One Roof

We develop REZ-CURE® one- and two-component heat-cure epoxies, ambient-cure and elevated-temperature-cure epoxy systems.

Bonding Across Difficult Substrates

Vehicles mix materials that resist easy joining. Our adhesives and epoxy primer systems grip galvanized, galvaneal, and galvalume metals, ceramics, glass cloth, EPDM, ABS, polycarbonates, and other thermoplastics while holding high shear and peel strength.

Direct Chemist Access and Fast Iteration

Program timelines leave little room for reformulation. Work directly with our chemists to iterate quickly while maintaining batch-to-batch consistency.

Application Areas

Where Automotive Bonding Systems Prove Themselves

Across the body shop, the electronics module, and the assembly line, engineers rely on our chemistry to hold and protect joints that fasteners alone cannot.

Hem Flange Bonding

Door, hood, and closure panels need a bond that seals and stiffens the flange without read-through. Our structural adhesive automotive systems bond hem flanges while resisting corrosion and vibration over the life of the panel.

Ignition Coils and Electronic Module Potting

Coils, sensors, and control modules face heat, vibration, and moisture. Our potting and encapsulation compounds insulate the assembly and protect signal integrity through every thermal cycle, holding dielectric strength where a general-purpose resin would crack or pull away.

Cable Harness Assemblies

Harnesses route through zones of constant motion and temperature change. Our adhesives anchor and protect connections, so they resist fatigue over long service lives.

Head Lamps, Bumpers, and Plastic Components

Lamps and bumpers combine plastics that many adhesives struggle to hold. Our automotive plastic epoxy bonds polycarbonate lenses, ABS, and painted surfaces, and an epoxy primer automotive step improves adhesion before assembly or repair.

Filter Manufacturing

Oil, hydraulic, and air filters rely on bonds that resist the fluids they handle. We engineer systems that seal and structurally join filter components, keeping media, end caps, and housings bonded through pressure and chemical exposure for a long service life.

Frequently Asked Questions

From substrate prep to production scale, explore answers to common questions about our automotive epoxy primer and adhesive systems.
Can your systems bond plastic bumpers and lenses?

Yes. Our automotive plastic epoxy and adhesive systems bond polycarbonate, ABS, and other thermoplastics used in lamps and bumpers.

What substrates can your automotive adhesives bond?

Our adhesive systems bond galvanized, galvaneal, and Galvalume® steel, as well as ceramics, glass cloth, EPDM, ABS, polystyrene, polycarbonate, and other thermoplastics.

Which chemistries do you formulate?

We work across heat-cure and ambient-cure REZ-CURE® epoxies, two-component polyurethane systems, and ACRYLIC-CURE® acrylic systems.

Can you match a specific cure schedule or performance spec?

Define your temperature range, cure schedule, and strength requirements, and our team will develop a system tailored to your application and support you from sample to production.

Do you supply automotive epoxy adhesive at production volume?

Yes. We scale automotive epoxy adhesive and epoxy primer automotive systems from lab samples to production while holding formulation consistent across every batch.

How do you handle structural bonds under vibration?

Our automotive structural adhesive systems distribute loads across the bond line and are engineered to withstand the vibration and fatigue of long-term vehicle operation.
