SUNSPACERS™ 04.X

Sunspacers™ 04.X are finely divided, optically clear, solid fused amorphous silica micronized powders. This product is specially engineered for paints, liquid and powder coatings, inks, adhesives, and thermoplastics, including UV curable compositions. These micronized powders increase corrosion resistance, reduce shrinkage, improve adhesion, and enhance surface qualities including abrasion, mar and scratch resistance. 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.

Features & Benefits

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.

  3. Anti-corrosion barrier.
  4. Mar, scratch, and abrasion resistance.
  5. Optical effects/color density.
  6. 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.
