AQUADEF Product Information

Storage

To prevent contaminants from impairing the quality, DEF by AQUADEF should be handled only in storage and filling systems intended exclusively for this purpose. Additionally, this handling helps to avoid high testing costs. AQUADEF users will be pleased to provide more information.

Since DEF by AQUADEF solidifies at -11°C and decomposes at an accelerated rate at temperatures above 25°C, storage and filling systems must be designed to assure a temperature range of between 30 and -11°C.

Degradability and disposal

DEF by AQUADEF is easily decomposed by microbes. The hazard which it poses to water and soil is therefore very low. Accordingly, it has been placed in the lowest water hazard class, WGK 1. Thanks to its outstanding degradability, small quantities of spilled DEF by AQUADEF can simply be flushed into the sewer with large quantities of water.

Danger and health

DEF by AQUADEF is an aqueous solution which poses no hazard under the relevant chemicals legislation. Furthermore, it is not classified as a hazardous substance under the relevant materials and transport regulations.

Should small quantities of DEF by AQUADEF come into contact with the skin during handling, it can simply be washed off with large quantities of water. A threat to human health can be virtually excluded.

Shelf life

Provided that the maximum recommended storage temperature of 25 °C is maintained, DEF by AQUADEF continues to meet the requirements of ISO 22241 for at least 12 months after production. Should this recommended storage

temperature be exceeded, this period is reduced accordingly. DEF by AQUADEF solidifies at -11°C. When reheated gently, the frozen DEF by AQUADEF returns to the liquid state and can be used as-is with no reduction in quality.
