Antique Brown® M38 Immersion Concentrate


Traditional Patina Solution to achieve a golden to chocolate brown brass patina, bronze patina, or copper patina

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.

Golden to chocolate brown on brass, bronze, copper.
