Introduction

KT 3900 is a methylbenzotriazole derivative that functions as a liquid, oil-soluble corrosion inhibitor and metal passivator. This high-performance additive is widely utilized in various lubricants and metalworking fluids. As a corrosion inhibitor, KT 3900 effectively protects metals including copper, copper alloys, cadmium, cobalt, silver, and zinc. As a metal passivator, it inhibits electrochemical corrosion on metal surfaces by precipitating metal ions, thereby preventing these ions from catalyzing oxidation reactions; this makes it a valuable choice for enhancing the performance and protective capabilities of lubricants and metalworking fluids across diverse applications.

Key Features

Corrosion Inhibition: As an effective corrosion inhibitor, KT 3900 protects various metals—including copper, copper alloys, cadmium, cobalt, silver, and zinc—from the damaging effects of corrosion, thereby extending the service life of components and machinery.

Metal Passivation: KT 3900 acts as a metal passivator, effectively precipitating metal ions and inhibiting electrochemical corrosion on metal surfaces. This function counteracts the catalytic oxidation potential of these ions, thereby reducing the risk of accelerated corrosion or metal degradation.

Oil Solubility: As a liquid, oil-soluble additive, KT 3900 blends easily with lubricating oils and metalworking fluids, providing effective corrosion protection and metal passivation without negatively impacting the oil's consistency or performance.

Function

Corrosion Inhibition: By forming a protective barrier on metal surfaces, KT 3900 acts as a corrosion inhibitor, thereby reducing the likelihood of surface corrosion. This protection is critical for extending component lifespan and minimizing the risk of equipment failure associated with corrosion-related wear.

Metal Passivation: By acting as a metal passivator, KT 3900 precipitates metal ions, thereby inhibiting electrochemical corrosion on metal surfaces. This passivation process prevents these ions from catalyzing oxidation reactions, thereby mitigating the risk of accelerated corrosion or metal degradation.

Compatibility: The oil-solubility of KT 3900 enables it to blend effectively with lubricating oils and metalworking fluids without negatively impacting product performance or consistency.

Application

Automotive Lubricants: The corrosion inhibition and metal passivation properties of KT 3900 are compatible with a wide range of automotive lubricants—such as engine oils, gear oils, and transmission fluids—helping to enhance performance and extend component lifespan in automotive applications.

Industrial Lubricants: Suitable for use in industrial lubricants designed for various types of machinery and equipment, particularly in applications where corrosion inhibition and metal passivation are critical for achieving optimal performance and maximizing component longevity.

Metalworking Fluids: As an effective additive for metalworking fluids used in cutting, grinding, and forming operations, the corrosion inhibition and metal passivation characteristics of KT 3900 ensure efficient performance, minimize component wear, and boost overall productivity during metalworking processes.
