As a leading Tolytriazole Sodium Salt supplier, we offer high-performance 50% TTA•Na liquid solutions specifically optimized for global water treatment and metal protection. Our technical team ensures rigid quality consistency across every batch to meet international industrial standards.
TTA•Na (Tolytriazole Sodium Salt) is a highly effective, water-soluble copper and yellow metal corrosion inhibitor. It forms a stable, micro-crystalline protective barrier on metal surfaces, blocking air and corrosive ions from degrading the substrate.
- Cooling Water Systems / Industrial Water Treatment: Prevents galvanic corrosion in multi-metal cooling circuits.
- Industrial Lubricants & Fluids: Excellent anti-corrosion additive for metalworking, cutting, and drilling fluids.
- Metal Detergents & Polishing: Protects sensitive copper components during industrial cleaning and surface treatment processes.
Tolytriazole sodium salt Description
Name: Tolytriazole sodium salt (TTA.Na)
Synonyms: Sodium tolyltriazole / Methylbenzotriazole sodium salt / Tolytrimer Sodium Salt / 1H-Benzotriazole / TTA Sodium Salt
Molecular Formula: C7H6N3Na
Molecular Weight: 155.13
CAS NO.: 64665-57-2
Melting point :-10 °C
Boiling point: 108 °C
Appearance: Amber transparent liquid
Properties: TTA•Na is a clear, yellowish-to-amber aqueous solution. It is highly soluble in water and functions efficiently across both neutral and alkaline environments. It forms a dense, uniform monomolecular film on metal surfaces, which provides superior protection especially when synergized with Mercaptobenzothiazole(MBT) or Benzotriazole(BTA).
Usage: Unlike standard solid Tolyltriazole(TTA), TTA•Na is an aqueous solution that is completely water-miscible. It can be directly dosed or blended into circulating water systems or fluid concentrates. For standard industrial cooling systems, an active maintenance dosage of 2–10 mg/L is generally recommended.
Package: Available in 200L plastic drums (250 kg net weight), 1000L IBC totes (1250 kg net weight), or customized bulk packaging based on requirements.
Storage: Store in a well-ventilated, shady, and dry warehouse. Keep containers tightly sealed to avoid prolonged exposure to air.
Hot tags: COBRATEC TT 85; COBRATEC TT50S

TTA Sodium Salt Applications
- Industrial Cooling Towers: Widely used in open evaporative cooling towers and closed recirculating systems to suppress copper corrosion and mitigate scaling risks in heat transfer equipment.
- Metalworking Fluids: Acts as an essential anti-wear and rust-preventative additive in synthetic and semi-synthetic lubricants, grinding fluids, and stamping oils.
- Antifreeze & Brake Fluids: Formulated into automotive engine coolants and hydraulic braking fluids to safeguard internal copper alloy components from cavitation and oxidation.
- Household & Industrial Cleaners: Added to specialty detergents and metal polishing solutions to prevent copper tarnishing during wash cycles.
FAQs about Tolytriazole Sodium Salt (TTA•Na)
Q1: What is the main advantage of using TTA•Na liquid over TTA solid?
TTA•Na is a 50% aqueous sodium salt solution, making it completely water-soluble and ready to use. TTA solid, however, is practically insoluble in water and must be dissolved in alcohol or alkaline solutions first. TTA•Na simplifies the dosing process, reduces operational labor, and eliminates the handling of chemical dust.
Q2: Can TTA•Na be used alongside other water treatment chemicals like phosphonates?
Yes, TTA•Na exhibits excellent compatibility with common scale inhibitors, biocides, and dispersants (such as HEDP, ATMP, and polyacrylic acid). In fact, combining TTA•Na with these treatments provides a strong synergistic effect, delivering simultaneous scale prevention and corrosion control.
Q3: How does TTA•Na compare to BTA•Na (Benzotriazole Sodium Salt)?
Both are excellent yellow metal inhibitors. However, TTA•Na contains a methyl group that offers slightly higher thermal stability and better solubility in certain organic formulations compared to BTA•Na. TTA•Na is often preferred in higher temperature cooling systems or specialized lubricants.
Q4: What are the standard loading capacities for 20GP container shipping?
For standard 250kg plastic drums, we can load 80 drums per 20GP container, totaling 20 Metric Tons (MT) with pallets. For 1250kg IBC totes, we load 18 totes per 20GP container, totaling 22.5 MT.
