Luster-On Aluminescent
is a product
used to form a conversion coating on aluminum surfaces without the use of hexavalent
chromium. Aluminescent is a replacement for yellow or clear hexavalent chromates and provides
excellent corrosion protection at low cost and forms a base for paint, lacquer, or rubber bonding. The
chromate can be applied by dip, spray, brush, swab, or roll coating, requires no electric current, cooling or
exhaust. Luster-On Aluminescent yields clear, slightly iridescent films while forming a protective surface
with lower electrical resistance than anodizing. Luster-On Aluminescent is suitable for both wrought and
cast aluminum alloys and is designed for ease of operation with minimum control.

Luster-On Tridescent
is a hexavalent-free trivalent chromate that provides 125 hours salt spray
protection. Tridescent is the clear replacement for yellow iridescent chromate films on zinc and zinc alloys.
It exceeds the requirements of ASTM B-633 Type II, may be baked at 400 F, and readily fits into existing
chromate cycles.
