    Business Information
    Shelf Life Details Protect the adhesive from exposure to light, especially UV light. Keep container closed while not in use. This is best done by opening the container for only the minimum time necessary, and opening only under yellow or red light. Any containers used for dispensing the adhesive must be light impenetrable. Store container in the dark at temperatures at or below 27°C (80°F). Do not freeze.
    Shelf Life Temperature (°F) <=80 (F)

  • Best Practices for Henkel 496

    *See Terms of Use Below

    1. Surface Preparation

      LITE-LOK 496 bonds well to many untreated surfaces. However, adhesion is often improved by surface preparation before bonding. The surface should be free of contamination such as dirt, dust, grease or oil. An alcohol wipe is suitable for cleaning most surfaces. Optimum strength is obtained by abrading the surface followed by a solvent wipe to remove any loose particles. Polyolefins must be corona treated, or flame treated before bonding.

    2. Application

      LITE-LOK 496 is best applied by extruding the product onto the substrate to be sealed or bonded. Sufficient product must be applied to seal all gaps, and completely coat the part to be bonded or sealed. After dispensing onto the part, the product should be cured as soon as possible to prevent any pre-reaction with ambient light.

      LITE-LOK 496 may be applied via a pressure pot, or piston pump dispensing system. All fittings and tubing used in the dispensing system must be opaque to light. If the product is transferred from a large container to a smaller hand held dispensing bottle, that bottle must be light impenetrable.
