Directions for use
Typical applications would utilise a mixture of MEG, technical water and a suitable WSS corrosion inhibitor to meet the required freeze protection requirement. Typical mixtures in Northern Europe are 50/50, offering frost protection down to -40°C. Mixtures with more than 70 vol. % MEG are not recommended. For optimal performance and controlled quality, we recommend the use of deionised or distilled water to prepare your required dilutions.
