Glass-bead blasting is used to make stainless-steel surfaces smoother and more even visually. The surface is blasted, reducing peaks and opening valleys without cavities (openings) at the micro level. A very fine surface profile is created, where dirt can only form deposits on the peaks. The adhesive strength is minimal, so that the surface remains cleaner and can be cleaned better.
ROTIN® is also used to glass-bead blast stainless-steel surfaces, but gives a better, faster and more attractive result due to the unique way it works. This rotating insert (ROTIN) is placed in the blast nozzle. This insert widens the jet proportionally, and sprays it at an oblique angle. Because the jet widens equally, it blasts every surface with equal intensity at every angle. The blasting is done at a lower pressure, 3 bar instead of 6 bar, and uses 40/70 glass beads instead of 100/200 beads.
Re-blasting or reworking is no longer necessary thanks to the wider, oblique jet. The surface is blasted neatly and smoothly first time round, with no patches and a finer surface profile than that achieved with standard glass-bead blasting.
