Description

Siloxanes And Silicones, Di-Me, Reaction Products With Silica is a specialized organosilicon compound resulting from the chemical reaction of dimethylsiloxanes/silicones with silica. This product is valued for its ability to impart unique surface-modifying properties, enhancing performance in demanding industrial formulations. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in plastics and composite materials, where it acts as a processing aid, rheology modifier, or reinforcing agent.

Application

• Coatings & Inks: Used as a flow and leveling agent, anti-settling aid, and matting agent to improve surface finish and application properties.
• Adhesives & Sealants: Functions as a rheology modifier and thixotrope to control sag and slump, enhancing application and performance.
• Silicone Elastomers: Acts as a reinforcing filler or processing aid to modify the physical properties and improve handling of silicone rubbers.
• Plastics & Composites: Employed as an internal lubricant and processing aid to reduce viscosity, improve dispersion, and enhance surface characteristics.
• Personal Care & Cosmetics: Serves as a texturizing agent and viscosity modifier in products like sunscreens, creams, and makeup.
• Industrial Lubricants & Greases: Used to modify rheological properties and improve the stability and performance of specialty lubricants.
