Polycarboxylate Superplasticier Macro-monomer(PC)–GPEG

Polycarboxylate Superplasticier Macro-monomer(PC)–GPEG

CHARACTERISTIC & APPLICATION This series of products are non-toxic, non-irritating and are important raw materials for functional polycarboxylate superplasticizer. The quality of these products are very stable when stored reasonable. Due to the special molecular structure, the space resistance of the polyether side chain is reduced, the swing of the side chain is more free, and the encapsulation and entanglement of the polyether side chain is improving. Polycarboxylate superplasticizer with excellent slump retention and good adaptability is formed by this series of macro-monomer copolymerize with acrylic acid. The synthesized PCE has good dispersibility and slump retention, high adaptability, high early strength and good viscosity reducing effects. It is especially suitable for projects using poor grave, poor cement or with high requirements for concrete. Packing Specification: Woven bag of 25Kgs. Storage: The product shall be stored in well-ventilated and dry places without direct sunlight and rain. Product shelf life: One year. SPECIFICATION
