  • Best Practices for Henkel Lite-Lok 476

    *See Terms of Use Below

    1. Surface Preparation

      LITE-LOK 476 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 476 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 476 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. (see Storage & Handling).

    3. Curing

      Optimum cure is obtained when LITE-LOK 476 is exposed to long wavelength UV light or short wavelength visible light. The peak reactivity of the product is from exposure to light from 365 nm through 420 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 476 will cure after a UV light exposure from two to five seconds, when cured at or near the focal point of the light source, and at the required energy levels stated below.

    4. Clean-Up

      Unreacted material can be cleaned up using acetone. If skin contact occurs, the affected area should be washed thoroughly with soap and water. Eye protection against UV light should be worn whenever the product is being used. Eye contact should be treated by thoroughly washing with water followed by medical attention. Aprons should also be used. Adequate ventilation is necessary to prevent inhalation of vapors.
