SN Flux 402
Polycarboxylate Copolymer
- 50% Aqueous polycarboxylic ether
- Delayed activation type
- Can be blended to other SN Flux® grades to give excellent slump retention
- Can be used for precast or ready-mix concrete
- Low air entrainment
It is delayed activation type polycarboxylic ether, which is designed for formulation water reducing admixtures with enhanced slump retention. It is suitable for formulation of high range water reducers/ superplasticizers where an enhanced slump retention performance needed. It has a delayed activation profile. It has low plasticizing effect right after the concrete is mixed. The polymer activates over time and slump loss is avoided. For higher initial slump/flow, it should be mixed with other Sn Flux® grades.
