3M™ Glass Bubbles K1

Technical DataSheet | Supplied by 3M

3M™ Glass Bubbles K1 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, shrinkage & warpage and 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 and viscosity. 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 K1 by 3M is used in caulks and adhesives.
