Title:
HYDROPHOBIC SILICA GEL FOR ENERGY-RAY-CURABLE COATING MATERIAL MATTING
Document Type and Number:
WIPO Patent Application WO/2021/220687
Kind Code:
A1
Abstract:
The present invention relates to a hydrophobic silica gel that has been surface-treated by a silicone oil, wherein the hydrophobic silica gel for energy-ray-curable coating material matting is such that the pore volume measured by a nitrogen adsorption/desorption method is in the range of 0.6-2 mL/g, the M value is in the range of 5-40 vol%, and the ratio (pore volume after compression/pore volume before compression) of the pore volume for a pore radius of 109 nm or less after compression at a pressure of 260 MPa to the pore volume for a pore radius of 109 nm or less before said compression is in the range of 0.8-1.5. According to the present invention, it is possible to provide a hydrophobic silica gel for energy-ray-curable coating material matting that has exceptional chemical resistance, scratch resistance, and sedimentation stability in addition to matting performance.
