Application

It gets from esterification of MPEG & MAA by acid catalyst, mainly used for producing high polycarboxylate water reducer.

Easy manufacturing method: Firstly putting some water into reactor, then diluted MPEG and MAA. After that, added drop by drop with aqueous solution of peroxide initiator, aging and neutralizing. If the additive is 0.2%, the water reducing rate is 30%.

It has high water reducing rate, good slump retention ability and less additive.

95% macromonomer is cream at lower temperature, the materials need to be melted and keep temperature at 50-70°C about 5-10 hours.

Package & Storage

Package is 200kg plastic drum, avoiding contact peroxide, far away from sunlight and heat, the shelf-life is 3 months.
