Hollow microspheres made from dispersed particle compositions

Abstract From the Canadian patent

Hollow microspheres made from dispersed particle film forming compositions comprising dispersed particles a binder, a film stabilizing, agent, a dispersing agent and a continuous liquid phase are described. Porous and non-porous hollow microspheres can be made. The hollow microspheres can be caused to have walls with voids which are interconnected to each other and to the inner and outer wall surfaces and can be used as membrane substrates in selective separation processes and in biotech processes. The hollow microspheres can be used as supports for catalysts and as enclosures for catalysts adsorbents and absorbents. The hollow microspheres can also be used as filler materials and as …
