MY-133-EA: Optical Coating / Adhesive

MY-133-EA is an Enhanced Adhesion version of MY-133-V2000. It includes a proprietary adhesion promoter which improves adhesion to glass, especially under wet conditions. The inclusion of the adhesion promoter shortens shelf life down to 6 months (compared with 12 for mY-133-V2000).  Its viscosity was designed to ensure maximal compatibility with re-coating units, as well as convenient manual re-coating.

Storage

  1. Avoid unnecessary exposure to ambient light and moisture.
  2. Long term storage should be at ambient conditions of 10-30ºC.
  3. The coating  is supplied in glass bottles. Keep container closed to avoid moisture penetration.
  4. The shelf life is 6 months.

Application

Curing can be achieved by any source of UV at 300-400nm. Typically, a dose of 1000-2000 mJ/cm2 is necessary.

To prevent tackiness on exposed surfaces, it is recommended to cure in an inert atmosphere (e.g. under nitrogen). There is no need for inert atmosphere when curing between two layers or in a mold (more on inert curing in the Technical Support page on our web site).

Keep the bottle closed in all times when not in use. The material is sensitive to light.

Safety: Refer to the SDS
