Usage

General Description

(Mercaptopropyl)methylsiloxane-dimethylsiloxane copolymers, also known as thiol-ene resins, are a class of silicone materials that contain both mercapto and alkene functional groups. These copolymers are widely used in various industrial applications due to their unique combination of properties, such as excellent adhesion, high flexibility, and good weatherability. They are commonly utilized as modifiers in adhesives, sealants, coatings, and elastomers, where they can improve the performance and durability of the final products. Additionally, (mercaptopropyl)methylsiloxane-dimethylsiloxane copolymers can also be used as a surface treatment agent to enhance the adhesion of different substrates, including metals, glass, and plastics.
