high hydrogen silicone oil
The methyl hydrogen-containing silicone oil emulsion and the methyl hydroxyl silicone oil emulsion are used together, so that the water resistance and the air permeability of the fabric can be maintained, the tear strength, the friction strength and the antifouling property of the fabric can be improved, and the hand feeling and the sewing performance of the fabric can be improved. In addition, it is used as a release agent and cross-linking agent for paper.
