Key Features of SC-71-SS
Controlled Reactivity:
~1.0% thiol content offers moderate functional activity, ideal for systems where excessive crosslinking or rapid curing must be avoided.Excellent Processability:
Moderate viscosity (~100 cP @25°C) ensures smooth integration into formulations and good flow behavior in application systems.Formulation Compatibility:
Soluble in aliphatic/aromatic hydrocarbons and dimethylsiloxane bases, allowing easy blending with coatings, adhesives, and silicone resins.Thermal & Chemical Stability:
Maintains stability under elevated temperature and oxidative environments for improved end-use performance.
Application Areas
SC-71-SS is engineered for industries where silicone-surface functionality and reactivity must be precisely tuned:
Mold Release Systems
Effective as a low-reactivity release agent for metal, rubber, and plastic moldings, minimizing buildup and extending tool life.Radiation-Curable Formulations
Functions as a reactive additive in UV and EB-curable inks and coatings, improving substrate wetting and crosslinking efficiency.Anticorrosion Metal Coatings
Provides chemical affinity to metal surfaces, improving barrier properties and adhesion of topcoat systems.Polymer Grafting & Copolymerization
Used as a reactive intermediate in silicone-organic hybrid synthesis or as a modifying agent in specialty polymers.
