🟤 Copper and Brass Polishing and Cleaning Paste – Production, Formulation and Properties
Overview:
Copper and Brass Polishing and Cleaning Pastes are semi-solid, high-performance formulations designed to remove tarnish, oxidation, and dullness from copper, brass, and bronze surfaces.
They combine micro-abrasive polishing agents and mild chemical cleaners, providing deep cleaning and brilliant shine without scratching or corroding metal surfaces.
These pastes are widely used in metal finishing, restoration workshops, and household maintenance, offering controlled cleaning strength and long-lasting results.
Their creamy consistency allows precise application, making them ideal for decorative objects, instruments, and industrial components requiring uniform polishing.
Production and Formulation:
Copper and brass polishing pastes are produced by blending ultra-fine abrasives, surfactants, waxes, binders, corrosion inhibitors, and polishing enhancers into a stable semi-solid base.
The formulation is mixed under controlled temperature to achieve a smooth, homogenous, and non-settling texture.
Optional additives such as anti-tarnish compounds, brightening agents, and fragrances may be incorporated to enhance gloss and usability.
The product is packed in jars or metal tubes, providing easy access for manual or mechanical polishing applications.
