Synthetic, hydrophobic, amorphous silica, produced via flame hydrolysis. Special features: White colloidal powder of high purity. Application: HDK® H13L is applied as a thickening, thixotropic and antisedimentation agent in coatings, printing inks, adhesives and others. It is mainly used in polar systems. Due to its strong hydrophobicity HDK® H13L is well suited for solvent free systems, for high solids and for waterborne coatings. Information provided by Wacker Chemie AG. |
