Coating composition

The coating comprises glass microspheres in an aqueous emulsion of a polymeric binder. The (optionally hollow) microspheres have average diameter = 5-100 micrometres (10-50 µm). The preferred composition comprises 20-40 (25-35) wt.% polymeric binder, 1-20 (3-10) wt.% sodium borosilicate glass, 25-50...

Zusammenfassung:	The coating comprises glass microspheres in an aqueous emulsion of a polymeric binder. The (optionally hollow) microspheres have average diameter = 5-100 micrometres (10-50 µm). The preferred composition comprises 20-40 (25-35) wt.% polymeric binder, 1-20 (3-10) wt.% sodium borosilicate glass, 25-50 (30-40) wt.% water, (0.95 wt.%) antimicrobial agent, (0.1 wt.%) zirconium pollen denaturing agent, (9.5 wt.%) flame retardant and (2 wt.%) thickener (rheology modifying agent). The preferred binder comprises vinyl chloride and vinyl acetate. Other exemplified additives are 14.25 wt.% white titanium dioxide pigment, 0.1 wt.% foam control agent and 1.9 wt.% humecant. The coated window blinds are also claimed. "Low e" gives the reflectance of a polyester blind fabric coated with the composition.
