Hydroxyl silicone oil is a linear polydimethylsiloxane with hydroxyl end groups, an oily liquid. It has the characteristics of methyl silicone oil. Low-cosity hydroxyl silicone oil is an excellent structure control agent in silicone rubber processing, which can replace diphenylsilanediol, simplify the process, and improve process performance. It is also used a waterproofing, softening, and anti-sticking treatment agent for fabrics, leather, and paper.
