3M™ Glass Bubbles S38HS

3M™ Glass Bubbles S38HS by 3M is a soda-lime-borosilicate glass filler. It is a chemically inert grade exhibits chemical resistance, water resistance, abrasion resistance and lower film permeability. Possesses 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 maintains or improves opacity, viscosity, flow, leveling and sprayability. It has long shelf life and the potential to lengthen time before condensation develops. Spherical shape reflects light effectively in all directions. 3M™ Glass Bubbles S38HS is used in many plastics and elastomers.
