TRUEGARD SS-266 Semi-Synthetic Coolant Concentrate

TRUEGARD SS-266 is a versatile semi-synthetic coolant concentrate engineered for a broad spectrum of grinding and machining operations on steel, copper, and aluminum alloys. It is ideally suited for processes such as drilling, milling, tapping, sawing, and turning, providing reliable performance across diverse manufacturing environments.

When mixed with water, TRUEGARD SS-266 yields a brilliant green solution that is hard water stable and non-gumming, ensuring smooth operation and easy maintenance. Its outstanding detergency keeps workspaces clean, while the absence of sulfur and chlorine enhances safety and user-friendliness.

TRUEGARD SS-266 is formulated with a balanced pH to protect nonferrous metals and maintain gentle contact with operators’ skin, minimizing irritation. The mild pH also helps preserve machine paint, preventing premature wear. Incorporating advanced biocide technology, TRUEGARD SS-266 effectively suppresses excessive bacterial growth, supporting long-term coolant stability and consistent performance.

Frequently asked questions

Find answers to common questions about our products and services

  • The refractometer factor of 3.1 is a multiplier you apply to your refractometer's Brix reading to determine the actual concentration of SS-266 in your sump. For example, a 2° Brix reading multiplied by 3.1 equals a 6.2% working concentration. Using this factor allows you to accurately monitor and maintain the correct mix ratio during ongoing use rather than relying on Brix readings alone.

  • SS-266 is a concentrate that must be mixed with water before use - it is not intended to be applied undiluted. Consult the product data sheet for specific dilution ratios suited to your operation type, and use a refractometer with the 3.1 factor to verify your working concentration.

  • Sulfur and chlorine additives, while effective in some cutting fluids, can cause staining or corrosion on sensitive metals such as copper and aluminum alloys, and may raise health and disposal concerns. By excluding them, SS-266 is safer for operators, more compatible with a wider range of workpiece materials, and generally easier to handle and dispose of responsibly.

  • Hard water contains elevated levels of dissolved minerals like calcium and magnesium that can cause some coolants to break down, form residues, or lose emulsion stability. SS-266's hard water stability means it maintains its properties and does not form deposits when mixed with typical hard tap water, reducing the risk of sump buildup and keeping maintenance demands low.

  • Bacterial growth in coolant sumps can cause foul odors, accelerated fluid degradation, reduced lubrication performance, and skin irritation for operators. The advanced biocide technology in SS-266 actively suppresses excessive bacterial growth, supporting a longer coolant service life and more consistent performance between sump changes.

  • Yes - SS-266 is specifically engineered for steel, copper, and aluminum alloys, and its balanced pH is designed to protect nonferrous metals from corrosion while remaining gentle on operators' skin. This makes it a practical choice for shops running mixed-material workpieces or switching between material types without changing coolants.
