Directions for use:
For Assembly
1:For best results, clean bond surfaces
2:to ensure a fast and reliable cure,activator 7649 should be applied to one of the bond surfaces and the adhesive to the other surface,parts should be assembled within 15 minutes
3:the recommended bondline gap is 0.1mm ,where bond gaps are large(up to a maximum of 0.5mm),or faster cure speed is required activator 7649 should be applied to both surfaces ,parts should be assembled immediately(within 1 minute)
4: Excess adhesive can be wiped away with organic solvent
5:Bond should be held clamped until adhesive has fixtured
6:product should be allowed to develop full strength befor subjecting to any servie loads(typically 24 to 72 hours
Optimal Storage:8℃ to 21°,store product in the unopened container in a dry location.
