Ultrafine Zinc oxides are outstanding mineral IR reflectors and UV absorbers which brings only a very low opacity to the products in which they are used due to a high refractive index (n = 2,008). They differ from conventional grades by the small primary particles size (nanofine) which leads to a very high surface area and to the absence of pigmentary characteristics.
Oxyde de Zinc Micropure - A nanofine grade of zinc oxide powder.
Oxyde de Zinc Micropure AS - Alkylsilane treatment improves the oil dispersion, decreases oil absorption and leads to easier grinding.
Covascreen ZN - An advanced dispersion of surface treated nanofine zinc oxide.
