Carboxylic acid water-soluble rust inhibitor
Carboxylic acids are the most widely used water-soluble rust-preventive additives, mainly including monobasic acid, dibasic acid, and tribasic acid. They also need to be neutralized with alcohol amine to generate carboxylic acid amine, which is an excellent rust-preventive additive used in metalworking fluids for short-term rust prevention.
Organic carboxylate and their derivatives contain polar groups such as -COOH and -CONH-, they have a certain affinity with metals and are easily adsorbed on the metal surface to prevent the metal from rust corrosion.
Here are some normal Carboxylic acids used in metal working fluids and related aqueous fluids, such as HFC hydraulic fluids.
Ternary organic polycarboxylic acid
Triazine polycarboxylic acid is an excellent rust preventive for ferrous metals.
Ternary polycarboxylic acid is widely used in various water-based lubricants and metal working fluids, organic acid technology (OAT) or semi-organic Hybrid Organic Acid Technology (HOAT) engine coolants, biodegradable water-based hydraulic fluids, etc.
Generally, Ternary polycarboxylic acid is acidic itself, the polycarboxylic acid is mixed with alcohol amines (e.g., triethanolamine ) at a mass ratio and stirred at a certain temperature to get the carboxylic amine, which is a weak alkaline (pH 8-10), it is widely used as a metal corrosion inhibitor additive in water-based products such as synthetic cutting fluids, semi-synthetic grinding fluids, water-based quenchants, and water-based cleaning agents.

Advantages of organic polycarboxylic acid anti-rust inhibitors
● Low treat rate, excellent anti-rust performance for ferrous metals
● No gel film on the metal surface
● Low foaming and good air release performance
● No aluminum corrosion
● Good hard water resistance
● used for multiple metals
● Eco-friendly without nitrite
Dodecanedioic acid (C12 dicarboxylic acid)
is an organic straight-chain dicarboxylic acid used as a metal rust inhibitor.
Sebacic acid (C10 dicarboxylic acid)
is an organic straight-chain dicarboxylic acid used as a metal rust inhibitor, plasticizer, etc
