Parker LORD 7420 Blue Urethane Adhesive, GA Regular Without Ears

Description

LORD 7420 adhesive is a blue one-part moisture-cure urethane used for bonding thermoplastics to fiber reinforcements. It gives shops a no-mix option when the process calls for a liquid urethane adhesive with clear color identification.

LORD 7420 adhesive Benefits

• One-part moisture cure removes ratio checks and static mixer waste from the application step.
• Blue color helps operators confirm coverage and identify the material on the line.
• Polyether-based urethane chemistry supports bonding of selected thermoplastics and reinforced parts.
• Liquid viscosity range supports coating, bead, or controlled application methods.
• Weathering and solvent resistance data support use in demanding bonded assemblies.

This product is a fit for buyers who already know their substrate stack and want a process built around a one-component urethane. As with any moisture-cure adhesive, storage, open time, humidity, and application thickness should be controlled.

LORD 7420 adhesive Applications

• Thermoplastic-to-fiber reinforcement bonding in industrial production.
• Nylon, TPU, CPE, polyester, and related plastic assemblies when testing approves the bond.
• Blue adhesive applications where visual confirmation helps inspection.
• No-mix urethane processes that do not need two-part cartridge dispensing.
• Repair or production cells using a specified 7420 process.

Surface Preparation and Use

Prepare substrates according to the approved process, then confirm moisture exposure, bead size, and cure timing before scaling. Keep containers closed when not in use. Do not apply over oil, dust, release agent, or loose surface contamination. Run a small panel before changing line speed or cure timing.

Technical Details and Documentation

Published technical references identify 7420 as a one-part blue polyether-based urethane with moisture cure, 200 to 700 cP viscosity, and use on thermoplastics and reinforced substrates. Review current guidance from Parker LORD before production use.
