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)	<81

Best Practices for Henkel Lite-Lok 492

*See Terms of Use Below
1. Surface Preparation
  
  LITE LOK 492 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 or plasma treated before coating.
2. Application
  
  LITE LOK 492 is best applied by extruding a droplet of the product onto the substrate to be coated. After dispensing onto the part, the product should be cured as soon as possible to prevent any pre-reaction with ambient light.
  
  LITE LOK 492 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 492 is exposed to long wavelength UV light. The peak absorption and reactivity of LITE LOK 492 is between 320 and 360 nm. The time needed for curing is a combination of many factors. Some of these are: The lower the intensity of the UV light source, 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 492 will cure after a UV light exposure from three to five seconds, when cured at or near the focal point of a high intensity UV light source. To achieve complete cure, all of the coating must be exposed to the UV light source.
4. Clean-Up
  
  Unreacted material can be cleaned up using acetone.

Spec Engine^® Results
- 4-20638(Dymax)
  A clear, decorative coating that cures in seconds upon exposure to long wave (365 nm) UV light. The coating has a low viscosity for thin coating applications and resists many solvents. 4-20638 has good adhesion to plastics, metal, glass and decals.
- 628-VLV(Dymax)
  Forms high strength bonds to glass, metal, phenolic, filled Nylon, ferrite, ceramic and other materials. Its low viscosity makes it most suitable for use as a protective coating, or in applications requiring bonding of very close fitting surfaces, or where wicking into cracks and crevices is desired.
- Loctite AA 366(Henkel)
  Highly resistant to vibration and impact forces. Used to bond, seal or coat metal and glass components in industrial applications.
