LETBOND® retaining compounds fill the “inner space” between components and cure to form a strong precision assembly. Formulated in a selection of viscosities、gap filling ability、flexibility and strength characteristics.
Directions For Use:
  1. For best results, clean all surface with LETBOND® cleaning solvent
  2. If the material is an inactive metal, spray with activator
  3. This product is not recommended for use on plastics
