Applications
Untreated Hydrophilic Fumed Silica K-150 is widely used in adhesives and sealants to improve viscosity control, prevent sagging, and enhance mechanical strength. Its thixotropic properties ensure easy application while maintaining structural stability in both solvent-based and water-based formulations.
Packing
K-150 is supplied in a paper bag of 10kg and a bigbag of customized quantity. The paper bag consistsof multiple layers and contains PE coated layerbetween the papers.
Storage
K-150 is a chemically stable material and does not degrade under normal conditions. However, to maintain optimal performance, the following storage guidelines should be followed:
Proper storage ensures that K-150 retains its high purity, flowability, and performance characteristics throughout its lifecycle.
