Description

Tego 103S is a specialized organosilicon-based surfactant and defoamer, widely recognized in industrial formulations for its exceptional performance. Its core value lies in providing highly effective foam control and surface modification in challenging, high-pH and solvent-based systems. This product is essential for manufacturers in the coatings, adhesives, inks, and construction chemicals industries who require reliable process stability and superior final product quality. Tego 103S CAS NO 8043-32-1 offers a robust solution for managing foam in aggressive environments where conventional additives may fail.

Application

• Defoamer and air release agent in water-based and solvent-based industrial coatings, including high-gloss paints and wood finishes.
• Foam control in construction chemical formulations such as cement-based plasters, self-leveling compounds, and tile adhesives.
• Process aid in the manufacture of printing inks and overprint varnishes to prevent foam during high-speed application.
• Additive for adhesives and sealants to eliminate entrapped air and ensure uniform film formation.
• Surfactant and wetting agent in agrochemical concentrates and emulsion formulations.
• Additive in industrial cleaning and metalworking fluids to control foam in alkaline or solvent-containing systems.
• Component in polymer emulsions and resin synthesis to improve process efficiency.
