Best Practices for Henkel Loctite AA F246
-
Surface Preparation
For best performance bond surfaces should be clean and free from grease.
-
Application
To ensure a fast and reliable cure, Activator Ini No.1™ or Ini No.5™ should be applied to one of the bond surfaces and the adhesive to the other surface. Parts should be assembled within 15 minutes. The recommended bondline gap is 0.1 mm. Where bond gaps are large (up to a maximum of 0.5 mm), or faster cure speed is required, Activator Ini No.1™ or Ini No.5™ should be applied to both surfaces. Parts should be assembled immediately (within 1 minute). Excess adhesive can be wiped away with organic solvent. Bond should be held clamped until adhesive has fixtured. Product should be allowed to develop full strength before subjecting to any service loads (typically 24 to 72 hours after assembly, depending on bond gap, materials and ambient conditions).
