  • Best Practices for Henkel Lite-Lok 495

    *See Terms of Use Below

    1. Surface Preparation

      LITE-LOK 495 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 495 is best applied by extruding the product onto the substrate to be bonded using a dispensing tip. 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 495 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.

    3. Curing

      Optimum cure is obtained when LITE-LOK 495 is exposed to high intensity UV-A light. The peak reactivity of the product is from exposure to light of wavelength from 325 nm through 365 nm. The time needed for curing is a combination of many factors. Some of these are:

      The thicker the substrate, the longer the exposure time needed for curing. The more UV light absorbing that the substrate is, the longer the exposure time needed for curing. The lower that the intensity of the UV light source is, the longer the exposure time needed for curing. The farther the distance of the product from the UV light source, the longer the exposure time needed for curing.

      Typically, LITE-LOK 495 will cure after a UV light exposure from one to three seconds, when cured at or near the focal point of a high intensity UV light source.

      To achieve complete cure, all of the product must be exposed to the UV light source.
