Description

Tego103G is a high-performance silicone-based surfactant and foam control agent, identified by CAS No. 36895-38-2. This specialized organomodified siloxane is engineered to deliver superior wetting, leveling, and defoaming properties in demanding industrial formulations. It is a critical additive for manufacturers in the coatings, adhesives, and polyurethane foam industries who require enhanced process stability and final product quality. Its balanced structure provides effective surface tension reduction and compatibility in complex systems.

Application

• As a powerful defoamer and foam control agent in water-based industrial coatings, inks, and adhesive formulations.
• As a wetting and leveling additive to improve substrate coverage and film formation in paint and coating systems.
• As a key surfactant in the production of flexible and rigid polyurethane foams to stabilize the foam structure and control cell size.
• As a process aid in industrial cleaning and metalworking fluids to prevent foam during application and circulation.
• As a surface modifier in construction chemicals, such as cement additives and gypsum-based products, to enhance workability.
• In agricultural adjuvant formulations to improve the spreading and adherence of pesticides and herbicides.
