Detailed introduction
JW double fast gelling agent is a new technology product developed by the technical personnel of our company under the guidance of experts and technology of China Academy of Building Materials Science. It is characterized by short setting time, fast hardness, 3 hours strength of not less than 20MPa, with the needs of basic engineering. Strong adhesive force, no shrinkage, no shedding, and maintain the late strength does not shrink. Mainly to meet the rush repair, anchoring and preparation of grouting material, anchor spray and other buildings.
