HDK® T40 is applied as a thickening and thixotropic agent in coatings, printing inks, adhesives, cosmetics and others. It is used as a reinforcing filler in elastomers, mainly silicone-elastomers. HDK® T40 acts as a free flow additive in the production of powder coatings

HDK®H 15 is a synthetic, hydrophobic, amorphous silica, produced via flame hydrolysis.

HDK® H30 is applied as a thickening and thixotropic agent in coatings, printing inks, adhesives, cosmetics and others. It is used as a reinforcing filler in elastomers, mainly silicone-elastomers. HDK® H30 acts as a free flow additive in the production of powder coatings

HDK® H20 is a synthetic, hydrophobic, amorphous silica, produced via flame hydrolysis.
