Salcromo
Salcromo is a specialty chemical used primarily as a corrosion inhibitor and surface treatment agent for metals. It helps prevent rust and corrosion on metal surfaces, enhancing their durability and lifespan. Salcromo is widely applied in industries such as metal finishing, automotive, and manufacturing to protect steel, iron, and other metals from environmental damage and oxidation.
Primary Uses
Metal Treatment & Protection
Used as a corrosion inhibitor in metal finishing processes to protect steel and iron components.
Applied in surface treatment baths to improve adhesion of subsequent coatings and paints.
Enhances resistance of metal parts to rust, especially in automotive and machinery manufacturing.
Manufacturing & Industrial Applications
Utilized in the production of metal parts and tools to prolong service life by reducing oxidation.
Incorporated in formulations for metalworking fluids and coolants to prevent corrosion during machining.
Secondary Uses
Construction
Used in protective coatings for structural steel to improve durability in harsh environments.
Electronics
Applied in surface treatments for metal parts in electronic devices to prevent corrosion and ensure conductivity.
