Chronital

CHRONITAL is used in all applications where non-rusting materials such as aluminum, zinc, stainless steel, brass, bronze, etc. are blasted.

CHRONITAL’s large spectrum of grain sizes makes it perfect for cleaning, de-burring, hardening and surface finishing of all types of castings, forgings, profiles, wire and welded structural parts, without the possibility that rust could discolor the bright surface due to ferritic dust.

CHRONITAL distinguishes itself by having a high percentage of spherical grains and by its compactness. The end result is low consumption, high performance and low machine wear.

Using CHRONITAL on smooth and textured pavers brings out the stones unique appearance, and the possibility of developing unsightly rust spots on the surface of blasted concrete and granite stones due to the remains of ferritic particles is ruled out.
