Title:
WATER-REPELLANT POWDER
Document Type and Number:
WIPO Patent Application WO/2018/143361
Kind Code:
A1
Abstract:
The present invention relates to a water-repellant powder for which, when the peak intensity generated by Si-O-Si bond network structures at wavenumber 1070 cm-1 in an infrared absorption spectrum measured using Fourier-transform infrared spectroscopy is specified as 1.0, the peak intensity generated by Si-CH3 structures near wavenumber 1270 cm-1 is 0.2–0.7.
