- Light Transmission
SUNSPHERES™ 15.0 transmit more than 85% of UV light having a wavelength of 200 nanometers and transmit more than 95% of UV light having a wavelength of greater than 300 nanometers. When dispersed in radiation curable coating formulations, these spheres allow pigmented and/or thick, clear coatings to be cured readily with ultraviolet radiation.

- Sizing & Use
SUNSPHERES™ 15.0 have a median particle size of approximately 15.0 microns, with 90% of particles passing 45 microns. Recommended dosages are 10 to 25% by weight of total coating formulation. SUNSPHERES™ are designed for use in thick coatings appropriate to their size. In thinner coatings, the SUNSPHERES™ 15.0 provide texture. Given the low surface area of the spheres, the viscosity of the coating resins can be decreased and the use of solvents can be reduced.
