TRIN-BEADS (Glass Beady:
A very popular media used primarily for dimensionally sensitive applications where tolerance and finish are your main concern. It is used widely by automotive rebuilders, die and mold makers, the plating and aircraft-aerospace industries. Trin-Beads are perfect for removing medium to light contamination without causing dimensional change, overstressing, imbedding or pitting. Mesh sizes range from extra coarse # 3 (20-30 mesh) to extra fine # 13 (170-325 mesh). Following are descriptions of typical applications:
COARSE – BT # 3 & 4:
Good for cleaning heavier contamination and peening for stress.
MEDIUM COARSE BT # 5, # 6, & # 7:
Good for engine rebuilding, mold texturing, and peening of softer metals.
MEDIUM – BT # 8, # 9, # 10:
Good for plating, anodizing preparation, and most general applications.
FINE – BT # 12 & # 13:
Good for cleaning light contamination and wherever a fine surface finish is desired.
