Instant brush on blackeners for metals

birchEden Prairie, Minnesota: Birchwood Technologies 3 brush-on metal blackeners–Presto Black BST4, Antique Black M24, and Aluma Black A14 are now available in smaller, quart sized (32 oz.) bottles for easier application and handling, at a new lower price point.

Presto Black BST4 Brush-On
Ideal for most iron and steel components, Presto Black BST4 Brush-On is designed for application on any size part in limited quantities. It solves the application challenges of immersion liquid products while producing an attractive, high quality, durable black finish. Can be sealed easily with a rust-preventative for extra finish protection.

Antique Black M24 Brush-On
Antique Black M24 Brush-On provides blackening or browning of brass, bronze and copper alloys. It produces pleasing US10B finishes on large architectural surfaces, sculptures and engravings – either new or reconditioned components. Reaction speed and finish color is easily controlled by diluting the concentrate with water. Can be used undiluted for darker finishes or diluted 1-50 percent for slower reactions and lighter, brown tones.

Aluma Black A14 Brush-On
Designed just for aluminum alloys, Aluma Black A14 Brush-On provides a durable, smooth black finish. Easily applied undiluted to blacken entire parts or use as a touch-up for black anodized parts that have been damaged or re-machined. Ideal for all types of aluminum parts including engravings.
