- Storage and Handling
- BECKOPOX™ EH 613w 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 40°C.
- It is essential to apply the paint within the time stated for pot life because the end of the pot life cannot be detected from an increase in viscosity.
MIXING RATIO AND POT LIFE
A blend of 100.0 g BECKOPOX™ EP 385w/56WA, 16.3 g BECKOPOX™ EH 613w/80WA and 13.7g 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.
- 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.
