Description
Chem-Set™ CMT3079 AA is a non-flammable, non-methylene-chloride air-assisted canister contact adhesive designed for industrial laminating and fabrication. Its air-atomized hybrid web/pebble pattern provides spray control for telegraph-sensitive substrates while delivering high bond strength and heat resistance.
Key Features
- Non-flammable adhesive/propellant system
- Non-methylene-chloride formulation
- Air-atomization control for a softer spray pattern
- Hybrid web/pebble spray pattern
- Fast 1–2 minute dry time
- One-hour open time
- HAP-free solvent as stated in the TDS

Application Guidance
Prepare clean surfaces free of dust, dirt and grease. Using an air-atomizing adhesive spray gun with compressed air, spray from approximately 6–10 in. (150–250 mm). Apply a consistent coating with 80–100% coverage and a minimum coat weight of 2.5–3.0 dry g/ft²; porous surfaces may require two coats. Allow the adhesive to dry completely, mate the substrates and apply 40–60 PLI using a nip roller or suitable J-roller. Full bond strength develops in approximately 24–48 hours. Avoid plasticized vinyl, flexible plastics, expanded/extruded polystyrene, polyethylene, polypropylene, copper/copper-alloy substrates, and copper/aluminum application components.
Typical Use Cases
- Decorative laminate bonding
- Telegraph-sensitive laminate applications
- Wood-panel lamination
- Leather and rubber bonding
- Compatible metal bonding
Target Industries and Buyers
- Cabinet and countertop fabricators
- Millwork shops
- Furniture manufacturers
- OEM fabricators
- Industrial laminators
Performance Advantages
The air-assisted system adds pattern control to a portable canister contact adhesive, allowing a softer spray where needed while maintaining the fast dry time and one-hour open time suited to production laminating.
