HDK® H13L is a synthetic, hydrophobic, amorphous silica produced via flame hydrolysis. It is a white colloidal powder of high purity. HDK® H13L is primarily used as a thickening, thixotropic, and anti-sedimentation agent in various applications such as coatings, printing inks, adhesives, and others. It finds its main application in polar systems. The strong hydrophobicity of HDK® H13L makes it particularly suitable for solvent-free systems, high solids formulations, and waterborne coatings.
