Introduction

The thiadiazole tertiary dodecyl thiol condensate is a liquid, ashless metal passivator renowned for its extreme pressure and antioxidant properties. This versatile additive is widely utilized in various automotive and industrial lubricants, as well as in metalworking fluids. It effectively prevents the corrosion of copper and copper alloys by active sulfur—even at low concentrations—making it an invaluable choice for enhancing the performance and protective capabilities of lubricants across a wide range of applications.

Specification 

Key Features

Ashless Formulation: Ashless components help minimize the potential for deposit formation, ensuring the lubricant operates at optimal levels while simultaneously reducing environmental impact.
Extreme Pressure (EP) Performance: Imparts superior extreme pressure properties to lubricants and metalworking fluids, enhancing wear protection under high-pressure and heavy-load operating conditions, thereby extending the service life of components and machinery.
Oxidation Resistance: Exhibits excellent oxidation resistance, inhibiting the formation of sludge, varnish, and other oxidation byproducts; this helps maintain the lubricant's essential performance characteristics, extends its service life, and reduces overall maintenance requirements.
Metal Passivation: Acts as a metal passivator, effectively neutralizing the corrosive effects of active sulfur on copper and copper alloys; this helps protect critical components and machinery, minimizing equipment wear and failures related to corrosion.

Function
