BECKOPOX™ VEH 2849w shows the same reactivity as BECKOPOX™ EH 613w and is especially suited for coatings on metallic substrates together with BECKOPOX™ EP 385w. BECKOPOX™ VEH 2849w shows improved stability of aqueous dilutions and better temperature stability during the dispersing process.
Applications & Uses

- Coating Type
- Special Properties and Uses
- BECKOPOX™ VEH 2849w is used together with solid epoxy resin dispersions or emulsified liquid resins.
- When used with BECKOPOX™ EP 385w coating systems for metallic substrates can be formulated with excellent water and saltspray resistance. The use of 80% of the stoichiometric curing agent quantity has given best results. At room temperature the film cures rapidly and can also be forced dried at elevated temperatures.
- When using solid epoxy resin dispersions, pigment dispersion is mostly carried out in the curing agent component. When reducing with water it should be ensured that the concentration is not lower than 20%. It is also important that the mill base temperature does not exceed 50°C.

MIXING RATIO AND POT LIFE
A blend of 100g BECKOPOX™ EP 385w/56WA 15g BECKOPOX™ VEH 2849w/80WA 15g deionized water has a processing time at 23°C of approx. 90 minutes. 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 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.
