- Product Highlights
- The Sunspheres™ 200 Nm efficiently transmit ultraviolet and visible light from 200 nanometers through the visible spectrum. They promote efficient and thorough curing of coatings with ultraviolet radiation.
- These engineered fused, amorphous silica nanospheres are resistant to temperatures greater than 1000 °C. and are chemically stable in a vast range of resins and pH. Dosage is 3 to 50% by total weight of the finished composition.
- The average particle size is 200 nanometers and range in size from about 50 nm to 500 nm. Silane surface treated Sunspheres™ 200 Nm are available upon request. New innovative dispersion technology for this product is available upon request.
