3M™ Glass Bubbles K37

3M™ Glass Bubbles K37 by 3M is a soda-lime-borosilicate glass filler. It is a chemically inert grade possessing chemical resistance, water resistance, abrasion resistance and lower film permeability. Exhibits low alkalinity, high strength, low-density of dry film, exterior solar reflectivity, low thermal conductivity, low dielectric constant, easier washability and scrub & burnish resistance. Offers high-build/low-slump, higher filler loading, reduced gloss, shrinkage & warpage, more uniform sheen, viscosity control at high PVCs with low solvent content. Is non-combustible and non-porous, so it does not absorb resin. It has long shelf life and the potential to lengthen time before condensation develops. Spherical shape reflects light effectively in all directions. It maintains or improves opacity, viscosity, flow, leveling and sprayability. 3M™ Glass Bubbles K37 is applicable in many plastics and elastomers.
