In the paper industry, hydroxy silicone oil is widely used as a base gel for anti-sticking agents. It is particularly effective in the treatment of label backing paper, asphalt packaging paper, carton sealing tape backing paper, and decorative paper backing. By applying hydroxy silicone oil, the cured film significantly enhances the anti-stick effect, preventing paper from sticking together during processing and storage. This feature makes it an indispensable additive in paper product manufacturing.

In the electrical and electronics industries, hydroxy silicone oil also plays an important role. It is used as a key component in insulating varnishes or as part of insulation materials. Its excellent electrical insulation properties make it crucial for protecting electrical equipment and improving safety, particularly in environments where high temperatures and humidity are present. This helps prevent electrical faults in devices that require reliable insulation.

In addition, hydroxy silicone oil has broad applications in the rubber industry. It is used as a base gel and diluent for condensation-type room-temperature vulcanized silicone rubber, particularly in the production of sealants and mold adhesives. The use of hydroxy silicone oil improves processability and enhances the quality of rubber products. By incorporating hydroxy silicone oil, the rubber manufacturing process is simplified, eliminating the need for heat treatment, while also increasing the transparency of the final product and improving labor conditions in the production environment.

For specialized applications, small-molecule hydroxy silicone oil (e.g., 25–30 CP, with about 8% hydroxyl content) is used as a structure control agent in silicone rubber. Its use not only effectively replaces diphenyl dihydroxy silane, simplifying the processing of silicone rubber, but also improves the transparency of the rubber, enhancing product quality. These advantages make it an essential raw material in the production of silicone rubber, particularly in applications that require enhanced transparency.
