Succinic Acid Rust Preventives Additives For Lubricating Oils
Advanced Water-Displacing Corrosion Protection for Industrial Systems
This advanced rust preventive is a light yellow to brown viscous liquid. Compared to conventional manufacturing processes, this new product offers high efficiency, low viscosity, stable quality, higher purity, stable acid value, good compatibility, light color, low toxicity, and odorless properties. These high-performance rust preventives are widely used in blending steam turbine oil, antirust oil, and antirust grease. They are especially effective in low viscosity and light color applications.
Product Introduction
This Succinic Acid Rust Preventive delivers superior metal protection through unique polar-nonpolar molecular design. Engineered for systems with water ingress risk, its carboxylic acid groups form chemisorbed monolayers that displace moisture and create hydrophobic barriers on metal surfaces, preventing rust in humid and marine environments. These innovative rust preventives provide exceptional protection against corrosion in challenging industrial settings.
- Water Displacement Mastery
100% displacement within 15 seconds (ASTM D665 A modified), making these rust preventives ideal for wet environments.
- Acid Neutralization
Neutralizes 8 mgKOH/g of organic acids (ASTM D664).
- Multi-Metal Protection
Simultaneously protects steel, cast iron, bronze (ASTM D665 variants).
- Hydrolytic Stability
<0.5% hydrolysis after 100h at 90°C (ASTM D2619).
- Food Safety Compliance
<0.1 ppm heavy metal leaching (FDA 21 CFR §178.3570).
