- Special Properties and Uses
- BECKOPOX™ EH 2189w is a highly reactive amine hardener for waterbased 2K epoxy coatings on metallic substrates.
- It is used together with solid epoxy resin dispersions like e. g. BECKOPOX™ EP 384w. Coating systems for metallic substrates can be formulated with excellent humidity and salt spray resistance. The use of 70-80% of the stoichometric curing agent quantity has given best results.
- BECKOPOX™ EH 2189w is highly reactive. Very fast drying and fast through curing coatings with at the same time excellent anticorrosion properties are obtained.
- The fast drying properties of coatings with BECKOPOX™ EH 2189w support formulation of textured paints.
- Processing Information
A blend of 100,0g BECKOPOX™ EP 384w/53WAMP and 14,1 g BECKOPOX™ EH 2189w/50WA has a processing time at 23°C of approx. 60 min. The end of processing time can not be seen by an increase of viscosity or gelation. Therefore it is necessary to use the material within the stated time limit.

- Storage and Handling
At temperatures up to 25°C storage stability packed in original containers amounts to at least 365 days.
BECKOPOX™ EH 2189w tends to crystallization at storage temperatures below 10°C or temperature variations. By this, the product will not suffer any damage, but the necessary regeneration requires extended heat treatment at 40-50°C with continuous stirring. Storage at temperatures less than 10°C must be avoided.
Lowest storage temperature: 10°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.
