FR-448-1-Photo-curing Adhesive for Lens Focus Bonding

Product code: FR 448-1
Manufacturer: Everwide
Package size:
Shelf Life: 1 year

FR448-1 is photo-curing adhesive. This product can fast cure under ultraviolet light(365nm). Cured resin has toughness and thermal shock resistance. Good adhesion strength after passing environmental aging test. It is suitable for fixing and bonding materials between plastics and plastics, and can be rapidly cured under the visible light. It is especially suitable for the fixed illumination of the point light source after the lens and lens holder are focused.
