Application Guidance
Apply adhesive evenly to both substrates using spray equipment, ensuring uniform coverage. Allow the adhesive to dry until tacky and does not transfer to the finger before mating surfaces. Join substrates within the working window and apply firm, even pressure to achieve full bond strength. Use in well-ventilated areas and keep away from heat, sparks, and open flames due to flammability. Properly ground equipment during application to prevent static discharge.
Typical Use Cases
- Laminating decorative surfaces to wood substrates
- Bonding metal to wood or composite materials
- Automotive and transportation interior applications (headliners)
- General fabrication and assembly operations
- Foam, laminate, and panel bonding in OEM manufacturing
Target Industries and Buyers
- Cabinet and furniture manufacturers
- Automotive and transportation manufacturers
- Industrial fabrication shops
- OEM assembly operations
- Laminating and panel processing facilities
