BRASS PRE-TREATMENT
Our advanced brass pre-treatment chemical series offers a unique conditioning solution engineered to meticulously prepare and restore copper-alloy surfaces for subsequent industrial processing or final presentation. Designed to operate through a seamless, multi-stage sequence, this high-performance system systematically targets and eradicates heavy surface contaminants, including stubborn manufacturing oils, deep-seated tarnish, and localized oxides. By combining aggressive degreasing agents with precision micro-etching components, the formulation completely strips away dulling scales to uncover the substrate's inherent, brilliant metallic luster. Beyond mere restoration, the treatment sequence concludes with an integrated passivation phase, depositing an invisible, ultra-thin protective barrier that effectively shields the freshly brightened brass against atmospheric moisture, oxidation, and subsequent flash corrosion.
Clinchem BR
Formulated for heavy-duty industrial preparation, Clinchem BR is an alkaline cyanide-based cleaner that provides an exceptionally robust, dual-action mechanism for completely conditioning brass surfaces. The highly alkaline matrix functions as a powerful degreaser, rapidly saponifying manufacturing oils, shop grease, and stubborn organic soils. Simultaneously, the free cyanide ions act as a potent chelating agent, dissolving tenacious copper and zinc oxides, scales, and deep-seated tarnish by converting them into highly soluble, stable cyano-complexes. This simultaneous cleaning and stripping action achieves an atomically clean, micro-etched substrate without attacking the underlying base metal or causing localized pitting. By completely eliminating both organic and inorganic barriers, this process leaves the brass surface thoroughly activated, highly hydrophilic, and perfectly prepped with the uniform surface energy required for subsequent electroplating, passivation, or chemical finishing.
Oleochem BR
Engineered specifically as the vital second stage in the brass conditioning sequence, our high-performance brass brightener solution transforms dull, activated substrates into a blemish-free, sparkling surface. Formulated to act rapidly on chemically cleaned copper-alloy components, this specialized solution utilizes precision micro-smoothing agents to level microscopic surface irregularities without compromising tight dimensional tolerances. By selectively removing the outermost muted metal layers left behind by the cleaning phase, it completely eliminates any residual haziness, streaks, or water spots, uncovering the deepest inherent warmth and brilliance of the brass alloy. The result is a highly reflective, uniform, and specular finish that maximizes visual appeal and provides the ideal, pristine foundation for final anti-tarnish passivation
Passivax BR
Serving as the definitive final stage in our advanced brass treatment sequence, our specialized passivation solution seals the pristine, specular finish to deliver long-term atmospheric protection without altering the alloy's dimensional or aesthetic properties. This high-performance formulation chemically reacts with the freshly brightened brass surface to build an ultra-thin, dense, and uniform passive layer that acts as an impermeable barrier against corrosive media. Engineered to meet rigorous industrial standards, this protective matrix effectively seals the substrate, allowing the treated brass components to withstand up to 120 hours of salt spray exposure in strict accordance with the ASTM B117 standard. By preventing copper leaching, moisture oxidation, and flash corrosion, this non-chromate passivation layer ensures the brass retains its blemish-free, sparkling appearance even under severe environmental or storage conditions.
