1. Product Overview: Engineered for Extreme Conditions

Easybond’s single-component polyurethane (PU) adhesive is a technically advanced formulation specifically developed for fire‑rated doors and other high‑safety applications. It cures by absorbing ambient moisture, forming a thermosetting structure that is insoluble and non‑melting. This ensures that the bond remains stable even under extreme heat, making it the ideal choice for doors that must pass rigorous fire tests and undergo high‑temperature stoving paint (baking finish) processes.

2. Exceptional High‑Temperature & Stoving Paint Compatibility

This adhesive is designed to meet the dual challenges of fire resistance and paint‑line compatibility:

• Outstanding Heat Resistance – Withstands temperatures exceeding 1200°C during fire exposure, while maintaining structural integrity across a continuous service range of ‑50°C to +250°C.
  
• Fully Compatible with Stoving Paint – The adhesive can withstand high‑temperature oven curing without degrading, blistering, or losing bond strength. This makes it perfect for fire doors that require a baked‑on paint finish.
  
• Structural Integrity Under Fire – Unlike ordinary adhesives that soften and delaminate, Easybond’s formulation keeps the door assembly intact, preventing premature collapse and ensuring the rated fire resistance is achieved.
  
• Certified Fire Performance – The product holds UL fire‑resistance certification, with industrial‑grade versions UL Classified for up to 4‑hour fire ratings – suitable for the most demanding commercial and industrial applications.
  

3. Core Advantages – Beyond Just Heat Resistance

• Superior Adhesion to Multiple Substrates – Forms strong chemical bonds with galvanised steel, cold‑rolled steel, paper honeycomb cores, rockwool, fibreglass, EPS/XPS foams, and other fire‑proof / insulating materials.
  
• Production‑Friendly Single‑Component System – No mixing required; can be applied manually or integrated into automated production lines. Offers adjustable open time to suit cold pressing, vacuum pressing, or other lamination processes.
  
• Clean & Safe – Low VOC (≤50 g/L), RoHS compliant (heavy‑metal free), and manufactured under ISO 9001 and ISO 14001 certified systems.
  
• Reliable Long‑Term Durability – Resists vibration, thermal cycling, and mechanical stress, with proven performance exceeding 2 million door cycles.
