MY-145 : Optical Coating / Adhesive
MY-145 is a low refractive index UV curable coating/recoating/adhesive. The adhesion is high at 600 gr/cm, and the modulus is 300 MPa. A typical application is re-coating in cascaded Cladding Light Strippers.

The product is supplied pre-filtered to below 1 micron particles.
- Avoid unnecessary exposure to ambient light and moisture.
- Long term storage should be at ambient conditions of 10-30ºC.
- The coating is supplied in glass bottles. Keep container closed to avoid moisture penetration.
- The shelf life is 12 months.
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.
