AgeSin® RA-FR16 series is a novel alkaline 还原剂 specifically designed for the synthesis of polycarboxylate ether (PCE) superplasticizers. It includes two forms: AgeSin® RA-FR16P(Powder) and AgeSin® RA-FR16L (Liquid). Both products effectively replace traditional 还原剂s (e.g., vitamin C, sodium formaldehyde sulfoxylate) in PCE production, enhancing fluidity retention and water reduction efficiency. They are stable in alkaline solutions and compatible with mainstream macromonomers like HPEG and TPEG.

PCE superplasticizer
Improves water reduction rate and slump retention of PCE
Enhances storage stability of PCE paste: no viscosity change or discoloration during long-term storage.
Reduces production costs compared to conventional 还原剂s.
Stable performance across a broad temperature range (0°C to 65°C).
Environmentally friendly and safe handling.
Use at 0.04‰ - 0.2% of the total reaction mass (optimize via lab tests).
Recommended initial dosage: 80%-100% of the original 还原剂 amount.
Add RO water and macromonomer (HPEG or TPEG) to the reactor. Stir until fully dissolved.
Add oxidizer/initiator at the target temperature.
Use one of these dosing methods:
Triple-dosing:
Dose 1: Acrylic acid/HEAA
Dose 2: Chain transfer agent (e.g., thioglycolic acid)
Dose 3: AgeSin® RA-FR16 还原剂
Dual-dosing:
Dose 1: Acrylic acid/HEAA + chain transfer agent
Dose 2: AgeSin® RA-FR16 还原剂
Control dosing time to 2-4 hours. Ensure AgeSin® RA-FR16 dosing finishes 15-30 minutes after acrylic acid.
Maintain temperature for 1-2 hours, then cool, neutralize with alkali, and dilute with water to obtain a clear or pale yellow PCE solution.
