All Metal Finishing Solutions are easy to use, produce authentic, consistent results, require no heat or electricity, are water based, nonflammable and react within minutes. Achieve a wide variety of antiqued and colored finishes on metal.
On brass and copper. Mix 15% concentrate with 85% water. Use as a dip at room temperature. 16 fl oz.
A316 liquid concentrate is used full strength or diluted with water to produce a natural verdi or patina green or bluish color on copper alloys. The natural looking finishes are produced by first treating the copper or brass surfaces with A311 to produce a brown finish. The subsequent A316 finish will adhere better to the brown finish than it will to bare copper or brass surfaces. Prior to charging a production tank, some experimentation should be done with properly prepared sample parts using various dilutions and immersion times to determine the conditions required to produce the desired color. Bluish finishes are obtained with no dilution of the concentrate or with dilutions of up to one (1) part concentrate to two (2) parts water and immersion times of one (1) to three (3) minutes. Greenish shades are developed by using dilutions of three (3) or more parts water and immersion times of one (1) to three (3) minutes. Antique finishes may be protected with a wax or lacquer top coat. The ultimate color will be influenced and enhanced by the top coat and it must be applied before judging the depth of color or before comparing with other antique finishes. The natural color of the alloy and the mechanical finish on the surface will also affect the final color of “highlighted” or burnished finishes.
