The instructions of type RA Dispersive Alumina ( Superplasticizer )
This product is activated ɑ-Al2O3 which has highly self-dispersal, in the presence of water, it becomes suspension and easily disperses into castable system or coating system, so that it can obtain self-dispersal. This product is perfectly filled in the gaps because of suitable size distribution and gravel shape, so that they become close stack. Meanwhile it has more accessible particle to increase the reaction activity. The higher ɑ conversion rate ensure low shrinkage in itself. These characters assure that product can fully play its excellent performance.
