Description
Mercaptan 405 is a high-performance sulfur-based corrosion inhibitor designed for petroleum products, lubricants, and industrial oil systems. With excellent metal adsorption ability and oil solubility, it provides reliable corrosion protection and helps extend equipment service life under demanding conditions.
Mercaptan 405 is characterized by its active mercapto (–SH) functional groups combined with optimized hydrocarbon chains. This structure ensures strong chemical affinity to metal surfaces while maintaining excellent solubility in mineral oils and most synthetic lubricants.
Key features include
● Strong adsorption on steel, copper, and alloy surfaces
● Excellent oil solubility without precipitation
● Effective corrosion inhibition at low treat rates
● Good thermal stability under normal operating conditions
These properties allow Mercaptan 405 to perform consistently in long-term industrial applications.
