- Description
- Technical specification
- Question & answer
LOCTITE® AA 3526 is a translucent, pale straw to amber, 1-part, medium viscosity, UV/visible light-cured, liquid modified acrylic adhesive. It cures rapidly to form flexible, transparent bonds when exposed to ultraviolet light and/or visible light of sufficient irradiance. The secondary cure system permits cure of product in shadowed areas.

How to use
For best performance bond surfaces should be clean and free from grease.
Cure rate is dependent on lamp intensity, distance from light source, depth of cure needed or bondline gap and light transmittance of the substrate through which the radiation must pass. Recommended intensity for cure in bondline situation is 40 mW/cm2 minimum (measured at the bondline) with an exposure time of 4-5 times the fixture time at the same intensity. For dry curing of exposed surfaces, mercury arc or electrodeless system are recommended.
Cooling should be provided for temperature sensitive substrates such as thermoplastics. Plastic grades should be checked for risk of stress cracking when exposed to liquid adhesive. Excess adhesive can be wiped away with organic solvent(e.g. Acetone). Bonds should be allowed to cool before subjecting to any service loads.
This product is light sensitive; exposure to daylight, UV light and artificial lighting should be kept to a minimum during storage and handling. The product should be dispensed from applicators with black feedlines.
FAQ
