Application
LUDOX® TMA colloidal silica along with n-amylamine has been used as surface active particles to stabilize foams from drainage, coarsening and coalescence.[1]
Other applications include:
Other applications include:
- Preparation of porous Bragg mirror and using it for flexible and biocompatible optical interference filters by infiltration of polydimethylsiloxane.[2]
- It acts as a filler and surfactant while preparing latexes by miniemulsion polymerization.[3]
- As a stabilizer for water-in-cyclohexane miniemulsions to form stable polyurethane shells via interfacial polyaddition.[4]
- Synthesis of organic-inorganic nanocomposite films from polyurethane dispersions and colloidal silica particles.[5]
