- Application Details
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. It is not suitable for pharmaceuticals, food and feed. A good dispersion of HDK® H30 is a must to assure optimum performance.
