Light Activated Resin - Uses

Uses

Dentists have used visible-light activated resins as adhesives for decades. Resin cements are utilized in luting cast ceramic, full porcelain, and veneer restorations that are thin or translucent to permit visible light penetration and thus polymerize the cement. Light-activated cements may be radiolucent and are usually provided in various shades since they are utilized in esthetically demanding situations.

Conventional halogen bulbs, argon lasers and xenon arc lights are currently used in clinical practice. A new technological approach for curing light activated oral biomaterials is presented. The new light curing unit (LCU) is based on blue light-emitting diodes (LED). The main potential benefits of LED LCU technology are: long lifetime of LED LCU (several thousand hours), no filters or cooling fan required, virtually no decrease of light output over lifetime with resulting consistent and high quality of material curing. Simple depth of cure experiments of dental composites cured with LED technology show promising results.

Industrial facilities are utilizing light-activated resin as a sealant for leaks and cracks. Some light-activated resins have unique properties that make it ideal as a pipe repair product. These resins cure rapidly on any surface, wet or dry.

Light-activated resins recently gained a foothold with fly tiers as a way to create custom flies, in a short period of time, with very little clean up involved. Manufacturers also use light curing systems in OEM assembly applications such as specialty electronics or medical device applications.
