Modified polyether TJ-188B
It is used to produce high performed polycarboxylic acid water reducing agent series.
It is the modified product of TJ-188, with better copolymerization. Its finished products-- common type polycarboxylic acid water reducing agent has better water reducing percent and slump-proof capacity, and can offer better performance in the production of special-purposed water reducing agents such as super-long slump-proof polycarboxylic acid water reducing agent and low-dose-polycarboxylic acid water reducing agent, and so on.
