MIL-DTL 5541F QPL approved Luster-On Aluminescent is a powdered product used to form a chromate 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. The product is also available in a liquid and thixatropic touch-up formulation.
