Trade Professional Information

• Required Tools: Application guns, mixing nozzles, trowels, brushes, clamps, cleaning solvents, safety glasses, gloves, appropriate PPE.
• Trade-Specific Tips: Thoroughly clean and prepare surfaces for optimal adhesion. Ensure accurate mixing ratios for two-part systems. Apply adhesive evenly and use appropriate clamping techniques. Allow sufficient curing time before subjecting bonded materials to stress. Clean tools immediately with recommended solvents. Protect uncured adhesive from moisture.
• Common Issues and Solutions:
  • Issue: Weak or inconsistent bonds. Solution: Verify substrate compatibility and preparation. Ensure accurate mixing and application.
  • Issue: Excessive foaming or expansion. Solution: Apply clear polyurethane glue in thin, even layers. Use appropriate application tools.
  • Issue: Difficulty removing cured adhesive. Solution: Clean uncured adhesive immediately with solvents. Use mechanical methods or specialized removers for cured adhesive.
  • Issue: Moisture sensitivity during curing. Solution: Protect uncured adhesive from moisture exposure. Ensure adequate ventilation.
