Application: LUDOX® TMA colloidal silica along with n-amylamine has been used as surface active particles to stabilize foams from drainage, coarsening and coalescence.
Other applications include:
• Preparation of porous Bragg mirror and using it for flexible and biocompatible optical interference filters by infiltration of polydimethylsiloxane.
• It acts as a filler and surfactant while preparing latexes by miniemulsion polymerization.
• As a stabilizer for water-in-cyclohexane miniemulsions to form stable polyurethane shells via interfacial polyaddition.
• Synthesis of organic-inorganic nanocomposite films from polyurethane dispersions and colloidal silica particles.

We are committed to transparency and moderation in this process.
