| Product Introduction | This is a two-component structural adhesive modified by introducing polyurethane elastomer into an epoxy resin matrix. It combines the high bonding strength and high rigidity of epoxy resin with the flexibility and impact resistance of polyurethane. |
| Product Advantages | 1. Balanced Strength and Toughness for High Load-bearing and Impact-resistance: It delivers high bonding strength for structural load-bearing, together with polyurethane-derived toughness for improved impact resistance and anti-delamination performance.
It provides good adhesion to metals such as steel, aluminum and galvanized sheets, as well as composite materials including FRP (fiberglass reinforced plastic) and carbon fiber composites.
Resistant to high-low temperature, humidity-heat aging, salt spray corrosion, and acid-base attack.
Adjustable two-component mixing ratio. Supports ambient temperature curing or heat-accelerated curing. Compatible with mechanical coating and manual dispensing. The cured adhesive can be sanded and painted. |
| Performance Parameters | 1. Full cure at ambient temperature: 24–48h 2. Heat-accelerated cure at 80 ℃: completed within 1–2h 3. Shear strength on metal substrates: ≥15MPa 4. T-peel strength: ≥8N/mm 5. Tensile strength: ≥20MPa 6. Elongation at break: 5–15% 7. Long-term operating temperature: −50℃ ~ +120℃ 8. Weathering stability: After 1000 h humidity-heat aging at 85 ℃ / 85% RH, performance retention rate ≥80% |
