HDK® H20 is a synthetic, hydrophobic, amorphous silica produced via flame hydrolysis. It is a white colloidal powder of high purity. HDK® H20 is used as a thickening and thixotropic agent in coatings, printing inks, adhesives, cosmetics, and other applications. It also serves as a reinforcing filler in elastomers, particularly silicone-elastomers. Additionally, HDK® H20 acts as a free flow additive in the production of powder coatings.
