| Product Introduction | This is a two-component polyurethane-based adhesive developed for automotive lightweight composite panels. Its core components are formulated polyether (Side A) and polymeric MDI (Side B). A tough and elastic adhesive layer is formed after mixed coating and curing, realizing firm bonding between different substrates. |
| Product Advantages | 1. High-compatibility Bonding for Multiple Substrates: Delivers strong adhesion to common composite panel substrates including paper honeycomb, glass fiber, metals and interior fabrics. Reliable lamination can be achieved without primer in most application scenarios.
Forms a high-strength elastic adhesive layer after curing. It bears structural supporting loads of composite panels and prevents cracking and debonding of the adhesive layer.
Adjustable two-component mixing ratio. Supports ambient temperature / heat-accelerated curing and adapts to industrial assembly line production.
Resists high-low temperature (−40℃ ~ +120℃), salt spray and humidity-heat aging, and maintains stable performance under complex outdoor conditions. |
| Performance Parameters | 1. Mixing ratio (Side A : Side B): 100:(25–40) (adjustable upon request) 2. Gel time: 15–60s (ambient temperature, ratio adjustable) 3. Full curing time: 24h (ambient temperature) / 30–60min (heat curing at 60–80℃) 4. Inter-layer peel strength (paper honeycomb/glass fiber): ≥0.2MPa 5. Bonding shear strength (metal/composite material): ≥3.0MPa 6. Long-term operating temperature range: −40℃ ~ +120℃ 7. Salt spray resistance: ≥500h, no blistering or delamination 8. Humidity-heat aging resistance: ≥1000h, bonding strength retention rate ≥85% 9. VOC content: ≤50μg/g (compliant with passenger vehicle interior standards) 10. Optional flame retardant rating: B1 class |
