Application Details

HDK® H30LM is applied as a thickening and thixotropic agent in coatings, paints, printing inks and adhesives, especially in epoxy, polyurethane and acrylate systems. HDK® H30LM is not suitable for pharmaceuticals, food and feed. A good dispersion of HDK® H30LM is a must to assure optimum performance.
