- Light Transmission
The SUNSPACERS™ 04.X transmit and scatter more than 85% of UV light having a wavelength of 200 nanometers and transmit and scatter more than 95% of UV light having a wavelength of greater than 300 nanometers. These micronized powders allow pigmented and/or thick, clear coatings to be readily cured with ultraviolet radiation.

- Anti-corrosion barrier.
- Mar, scratch, and abrasion resistance.
- Optical effects/color density.
- Oenhanced UV curing.
- Sizing & Use
SUNSPACERS™ 04.X have a median particle size of approximately 3-4 microns, with a particle size range of 0.5 microns to 13 microns. Recommended dosages range from 3 to 50% by total weight of formulation. Due to their low surface area, the SUNSPACERS™ 04.X are easily dispersed.
