Automotive Body-Assembly Adhesive

Description
Product IntroductionThis is a one-component moisture-curing polyurethane adhesive specially developed for the manufacturing and assembly of van body vehicles (trucks, coaches, refrigerated trucks, converted RVs, etc.). It integrates high-strength bonding, waterproof sealing and elastic vibration-damping properties in one product.
Product Advantages

1. Multi-substrate Compatibility, Combined Bonding and Sealing:

 Achieves firm adhesion to various van body substrates with integrated sealing and waterproofing functions.


2. High Strength & High Elasticity for Vibration-resistance and Crack Prevention:

 The cured adhesive layer delivers high strength and excellent elasticity, effectively buffering vibration and deformation to secure bonding stability of vehicle van bodies.


3. Excellent Weather Resistance for Long Service Life:

 Great tolerance to high and low temperatures, UV resistance and salt spray resistance. It provides long-term reliability up to 15 years and fits full-range application scenarios for van body vehicles.


4. Good Application Compatibility:

 One-component moisture-curing formula with no sagging during vertical surface application. Suitable for machine coating and manual coating. The cured bead can be sanded and painted, compatible with both production line and repair work applications.

Performance Parameters1. One-component moisture curing: Tack-free time: 15–30min; full cure time: 24–48h under 25℃ / 50%RH
2. Shear strength on metal substrates: ≥1.0MPa
3. Elongation at break: ≥300%
4. Operating temperature: −40℃ ~ +80℃
