Melflux SELECT 5691 F
Melflux SELECT 5691 F
Melflux® SELECT 5691 F is a free-flowing, spray dried powder of modified polycarboxylic ether. It is especially optimized for plastification and water reduction of binary construction materials (based on α- or β- hemihydrate with a small amount of Ordinary Portland Cement).
Melflux SELECT 5691 F provides a long workability and an excellent development of early strength.
Applications
- Self-leveling underlayments – SLUs (binary, HH-rich/OPC)
- Flowing floor screeds (binary, HH-rich/OPC)
Features & Benefits
- Binary binder compositions: hemihydrate as main binder and Portland cement as a secondary binder
- Specific dispersing effect
- Very low VOC emission
- Cheap and robust binder composition for SLU
- Very robust towards temperature deviations and high level of water resistance
- Individual adjustment of workability and setting times
- Constant flow values over a long period of time
- No retardation of cement hydration
- Excellent early and final strength
