PERMABOND 735

PERMABOND 735 is a black, toughened ethyl cyanoacrylate adhesive developed for joints that need more impact and peel resistance than a conventional cyanoacrylate. Typical viscosity is 100 to 200 mPa s at 25 deg C with a maximum gap fill of 0.15 mm. Its deliberately longer fixture time on metals provides additional alignment time before the joint sets, while rubber and phenolic surfaces fixture more rapidly. The cured adhesive reaches typical steel shear strength of 24 to 30 N/mm^2, peel strength of 40 to 60 N/25 mm, and impact strength of 5 to 10 kJ/m^2.

Key features

• Toughened Impact and Peel Performance: Typical cured properties include 40 to 60 N/25 mm peel strength and 5 to 10 kJ/m^2 impact strength.
• Longer Alignment Window: Metal fixture times of about 30 to 50 seconds provide more time for accurate alignment.
• Black Visual Bondline Identification: The adhesive is supplied black for assemblies where a dark bondline is preferred.

Applications

Bonding metals, plastics, and elastomers where a toughened instant adhesive with improved impact and peel performance is required.
