3M™ Glass Bubbles K15 by 3M is a soda-lime-borosilicate glass filler having low alkalinity, high strength, low density and lower film permeability. Shows chemical-, water-, abrasion-, scrub and burnish resistance. Offers uniform sheen, high-build/ low-slump, higher filler loading, reduced gloss, shrinkage and warpage. Recommended for oil & gas outdoor storage tanks, cryogenic tanks & tankers and gel coats for boat cabins. Exhibits chemical inertness, exterior solar reflectivity, low thermal conductivity, low dielectric constant and easier washability. It improves opacity, viscosity, flow, levelling and sprayability. 3M™ Glass Bubbles K15 is also used in solar reflective coatings for roofs, exterior walls, mobile phones, caravans, refrigerated storage warehouses and refrigerated trucks. Applicable for architectural, anti-condensation and industrial paints & coatings like maintenance coatings for bridges, truck under-carriages & other exposed metal structures and epoxy floor coatings.
