• A general-purpose blackening and browning concentrate for brass, bronze and copper alloys. Rapid reaction makes M20 ideal for use on manual finishing lines. Contains buffering agents which make the solution resistant to low level contamination or carry-over without affecting finish color or coverage. Use at 20% by volume for black finishes; 10-15% for a full range of pleasing brown tones.

• A unique brush-on concentrate for blackening or browning of brass, bronze or copper alloys. Produces pleasing US10B finishes on large architectural surfaces, sculptures, or engravings -- on new or reconditioned parts. Color and reaction speed can be controlled by diluting with water.

• Antique black gels - Blackening GEL designed for finishing decorative metalwork. These new GELS are designed for use by both individual metalworkers and for factory-scale antiquing lines. They make the finishing process faster, neater and far easier, reports the manufacturer.
• The brush-on GELS represent a new, more efficient finishing option to anyone using immersion or swab-on finishing processes. While immersion tank lines are most economical in many factory settings, brush-on techniques prevail in shops dealing with larger workpieces and customized finishes. The antiquing GEL process provides both of these finishers with a faster, cleaner and more cost-effective alternative.
• Large workpieces using liquid blackeners, for example, are challenging to work with due to difficulties of applying the liquid to a large surface uniformly. Another problem is minimizing the runs and drips during the finishing cycle and re-applying the liquid where needed to carry the blackening process to completion. Following blackening, these workpieces need careful rinsing and drying to avoid any tendency to waterspot or corrode. Each of these steps can reduce the level of operator control needed to achieve satisfactory results.
• By contrast, the new antiquing GELS simplify the process and eliminates most of these problems. After cleaning the part surface in the normal manner to remove cutting oils, coolants, etc., the user simply swabs-on a generous layer of antiquing GEL with a synthetic paint brush. Then allows the GEL to work for two to ten minutes. The GEL adheres to the metal surface and tones uniformly without running off – even on vertical surfaces. With most parts, no re-application of the GEL is necessary.
• When the desired depth of black tone is achieved, the GEL is simply rinsed off in the normal manner, leaving behind an invisible protective finish which inhibits water-spotting and corrosion during drying. The resultant toned finish is clean and tightly bonded to the substrate and can be sealed and used as-is, or highlighted to produce a variety of attractive distressed finishes.

• A versatile cold browning concentrate for copper, brass or bronze. Ideal for use in barrel lines or automatic lines, the reaction is slower (1-4 minutes) to allow the operator to stop at light or medium brown tones with ease, as well as chocolate browns on brass, bronze or copper alloys. Use at 20% by volume for darker tone, 10-15% for lighter browns, or undiluted for rich brown brushed-on finishes.

• A cold blackening concentrate for steels. A non-dimensional Presto Black finish is a low cost way to achieve good corrosion protection and enhance sales appeal. With a uniform .000030 inch (1 micron) thickness, the porous crystalline structure of the black finish makes it an excellent absorbent base for a rust preventive top coat. Once sealed, the Presto Black finish resists up to 1,200 hours humidity test without chipping or peeling.

• Blackener for Iron and Steel. New Room Temperature Presto Black® Gel For Iron And Steel Introduced -- Enhances Metal Coating Capabilities. Designed for use on any size part in limited quantities, the new Gel solves the application challenges of liquid products while producing an attractive, high quality, durable black finish.

• PRESTO BLACK GEL simplifies the metal blackening operation. After cleaning the part surface in the normal manner to remove cutting oils, coolants, etc., the user simply swabs on a layer of PRESTO BLACK GEL with a synthetic paint brush. Then allows the Gel to work for two to ten minutes. The Gel adheres to the metal surface and blackens uniformly without running off – even on vertical surfaces.

• With most parts, no re-application of the Gel is necessary. When the desired depth of black is achieved, the Gel is simply rinsed off in the normal manner, leaving behind an invisible protective finish which inhibits water-spotting and corrosion during drying. The resultant black finish is clean and tightly bonded to the metal substrate, and can be sealed with BIRCHWOOD CASEY DRI TOUCH® PLUS IRP3 non-tacky rust preventive for maximum service life.
• Ideal for finishing prototype and short run metal fabricated parts, PRESTO BLACK GEL can be used for blackening sharpened cutting tools, for molds, dies and on previously blackened parts that have been re-machined.
