Synthetic, hydrophobic, amorphous silica, produced via flame hydrolysis.
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 solventfree systems, for high solids and for waterborne coatings.
HDK® H13L is not suitable for pharmaceuticals, food and feed.
A good dispersion of HDK® H13L is a must to assure optimum performance.
More detailed information about the application and processing of HDK® H13L is available in our HDK-brochures and on the WACKER web site.
HDK® H13L is offered in following packaging:
- pallet with paper bags: 10 kg bags
- Big bags: 200 kg (big bags on pallets)
The 'Best use before end' date of each batch is shown on the shipping label and the certificate of analysis.
HDK® H13L should be stored in the original packaging in dry storage areas. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
