LOCTITE AA 3491 - 25ml (acrylic adhesive, universal, UV cured)
Product description:
LOCTITE AA 3491 cures in seconds upon exposure to ultraviolet radiation of 365nm to form an impact resistant bond which exhibits excellent resistance to prolonged humidity or water immersion. Typical applications include bonding and sealing or potting applications of glass to itself or other materials, such as rough surface decorative glass, molded glass tableware items or automotive lighting components. Further information about the product: biuro@woronko-kleje.pl
Steps to achieve the best adhesive results:
1. This product is light sensitive; exposure to daylight, UV light and artificial lighting should be kept to a minimum during storage and handling.
2. The product should be dispensed from applicators with black feedlines.
3. For best performance bond surfaces should be clean and free from grease.
4. 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.
5. Recommended intensity for cure in an adhesive application (between substrates) is 40mW/cm² minimum (measured at the bondline) with an exposure time of 5-6 times the fixture time at this same intensity.
6. For tack free surface cure, as necessary in coating, potting or tacking applications, higher intensity UV is required (100mW/cm² minimum).
7. Cooling should be provided for temperature sensitive substrates such as thermoplastics.
8. Plastic grades should be checked for risk of stress cracking when exposed to liquid adhesive.
9. Excess uncured adhesive can be wiped away with organic solvent (e.g. Acetone).
10. Bonds should be allowed to cool before subjecting to any service loads.
Storage:
Store product in the unopened container in a dry location. Storage information may be indicated on the product container labeling.
Optimal Storage: 8 °C to 21 °C. Storage below 8 °C or greater than 28 °C can adversely affect product properties. Material removed from containers may be contaminated during use. Do not return product to the original container.
Henkel Corporation cannot assume responsibility for product which has been contaminated or stored under conditions other than those previously indicated.
