The production process of alumina powder is getting higher and higher, and it is possible to produce alumina powder of less than 1 micron. The nano-alumina transparent liquid XZ-LY101 body color is colorless and transparent. The nano-alumina transparent dispersion uses 5-10 nm of alumina, which is an alumina that has been subjected to layer-by-layer deep processing of nano-alumina, and is added to various acrylic resins, polyurethane resins, epoxy resins, Aqueous liquid of melamine resin, silicone-acrylic emulsion and the like, added in an amount of 5% to 10%, can improve the hardness of the resin, the hardness can reach 6-8H, completely transparent, and the nano-alumina liquid can be aqueous or oily. Any solvent can be used to make various glass coating materials, precious stones, precision instrument materials, etc. Fabric Dyeing,Leather Dyestuff,Sulphur Dyes Tianjin Zhaobo Chemical Co., Ltd. , http://www.tjaciddyes.com
