GLASS BEADS
HIGHLIGHTS
Description : Glassbeads are a non-metallic mineral abrasive, made of soda glass.
Applications : Glassbeads are used for shotblast-cleaning, descaling and deburring. They are also suitable for inspection blasting (fraction and fracture detection) and for glarefree, decorative matt satin finishing. Another application is micro peening. When using glassbeads, there is no abrading or scouring action, no deformation of material and no contamination or embedment of particles. Glass beads are suitable for dry compressed air blasting as well as for wet blastcleaning.
