| Product Introduction | This is a high-strength, high-toughness structural adhesive chemically cured by mixing Component A (polyurethane prepolymer) and Component B (curing agent / chain extender) at a specific ratio. After curing, it forms an elastomeric bonding layer with structural load-bearing capacity as well as impact resistance and deformation resistance properties. |
| Product Advantages | 1. Balanced Strength and Toughness, Excellent Load-bearing and Impact-resistance: Cured adhesive delivers high load-bearing performance and durability to prevent cracking and debonding of the adhesive layer.
It exhibits outstanding adhesion to metals and composite materials, suitable for multi-material combinations of automotive composite panels.
Resistant to high-low temperature (−40℃ ~ +120℃), salt spray and humidity-heat aging; maintains stable performance under harsh environments.
Mixing ratio of the two-component system can be adjusted as required. It supports ambient temperature or heat-accelerated curing, and is applicable for both machine coating and manual coating, meeting mass production and repair service requirements.
Zero emission of harmful solvents such as benzene homologues. It satisfies environmental requirements for automotive manufacturing and matches production standards for high-end lightweight vehicles. |
| Performance Parameters | 1. Shear strength on metal substrates: ≥10MPa 2. T-peel strength: ≥20N/mm 3. Elongation at break: ≥300% 4. Full cure at ambient temperature: 24–48h 5. Heat-accelerated cure at 80 ℃: 1–2h 6. Long-term operating temperature: −40℃ ~ +120℃ 7. Salt spray resistance duration: ≥1000h 8. After 1000h humidity-heat aging at 85 ℃ / 85%RH, performance retention rate ≥85%; excellent thixotropy |
