- Special Properties and Uses
Hardener for water-reducible coatings on mineral and metallic substrates, hydryaulic epoxy mortars (ECC).
- Processing Information
- BECKOPOX™ EH 623w 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 116 and the solid resin dispersions BECKOPOX™ EP 384w and EP 385w (preferably in combination with liquid EP-resins) to produce water-thinnable paints hardening at room temperature with good adhesion to all mineral substrates.
- Drying at elevated temperatures (>60°C) should be avoided. At such conditions traces of acrylonitrile will be released.
- If the hardener is diluted with water there may be stability problems at solid concentrations of less than 20%, especially at storage temperatures above 35°C.
- When pigments and fillers are being dispersed in the hardener, the temperature must not be allowed to rise above 40°C.
- These paints retain a constant gloss irrespective of thinning ratio or the time between mixing and the end of the pot life.
- BECKOPOX™ EH 623w may be used in combination with BECKOPOX™ EP 128 as an additive for hydraulic mortars, the mechanical properties of the cured system being considerably enhanced by the additive.
MIXING RATIO AND POT LIFE
A blend of 50 g BECKOPOX™ EP 122w, 50 g BECKOPOX™ EH 623w, 50 g deionized water has a processing time at 23°C of approx. 2-3 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.

- 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 temperatues 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.
