3M™ Glass Bubbles S 22 - 1Kg

hollow glass microspheres, average grain size 29 µ, largest bubbles 53 µ

Especially for colorants and stuccos. Glass Bubbles are made of borosilicate glass with low alkali content, so they can be mixed with cement. They have an average volume of 8 l/kg, making them an economical solution for the application of light loads. At 125 gr. of ground glass per liter of mortar, the specific gravity of the mortar can be divided by two. This ground glass is an exceptional heat and temperature insulator.
