Product Introduction
This adhesive excels in bonding metals, woods, plastics, rubbers,
and masonry with high peel/shear strength. Its contrasting-color
components aid mixing visibility, retaining strength after
environmental aging. It resists extreme shock, vibration, and
flexing, ideal for cryogenic bonding and thermal cycling potting.
Product Special Attributes
Flexibility: Shore D hardness 50-65 (ASTM D2240) ensures impact resistance.
Processing: 90-min work life (100g @24°C); full cure in 7 days@24°C or
2hrs@150°C.
Electrical: Dielectric strength 408 V/mil, volume resistivity 1.9×10¹² ohm-cm
(@500V DC).
Thermal: Conductivity 0.228 Btu-ft/ft²h°F, CTE 102×10⁻⁶ in/in/°C (0-40°C).*
Application scenarios
Applications include aerospace cryogenic components, automotive
plastic bonding, electronic potting, and industrial repairs. Key
