Features & Benefits
- Distinguishing Features
- BECKOPOX™ EH 2162W is a hardener for concrete coatings with lower viscosity and longer pot-life use time than the standard hardener for concrete coatings BECKOPOX™ EH 623w. The pot-life extension is particularly when formulated at lower VOC levels and used in combination with liquid EP-resins.
- BECKOPOX™ EH 2162W is lower in reactivity compared to BECKOPOX™ EH 613w.

- Special Properties and Uses
Hardener for water-reducible coatings on mineral and metallic substrates.
- Processing Information
- BECKOPOX™ EH 2162W is used in combination with the water emulsifiable liquid resins BECKOPOX™ EP 122w, EP 147w and other liquid resins such as BECKOPOX™ EP 140, EP 128 and the solid resin dispersions BECKOPOX™ EP 384w and EP 2384w (preferably in combination with liquid EP-resins) to produce water-thinnable paints hardening at room temperature.
- Drying at elevated temperatures (>60°C) should be avoided. At such conditions traces of acrylonitrile will be released.
- When pigments and fillers are being dispersed in the hardener, the temperature must not be allowed to rise above 40°C.
MIXING RATIO AND POT LIFE
A blend of 100.0g BECKOPOX™ EP 147w and 116.5 g BECKOPOX™ EH 2162W has a processing time at 23°C of approx. 3 hours. The termination point cannot be visually seen through viscosity increase or gelation. Therefore it is necessary to use the material within the stated time limit.

Storage & Handling
- Shelf Life
- 1 Year
- Storage and Handling
- At temperatures up to 25°C storage stability packed in original containers amounts to at least 365 days.
- Synthetic resins containing water may freeze or get inhomogeneous at temperatures below 0°C. By this the product will not suffer any damage, but the necessary regeneration requires extended heat treatment at 40-50°C with continuous stirring. It is therefore recommended to ensure frostproof storage of such products.
- Lowest storage temperature: - 15°C
- When handling and processing epoxy resins and hardeners, the rules and regulations established by local authorities should be observed. A Material Safety Data Sheet is available on request.
