Introduction
AgeSin® RA-FR06, developed by Sinocure Chemical Group, is an organic sulfinic acid derivative sodium salt reducing agent designed for emulsion polymerization systems. With its exceptional reactivity, environmental benefits, and versatile applications, RA-FR06 stands as a viable, high-performance substitute for Bruggolite FF6M in redox-initiated free radical polymerization.
Key Advantages Over Conventional Reducers
-
Enhanced Reactivity & Efficiency
-
Forms highly active redox systems with peroxides (e.g., ammonium persulfate, tert-butyl hydroperoxide), enabling rapid free radical generation even at low temperatures (60–75°C).
-
Reduces residual monomers (e.g., in acrylic, VAE, and styrene-butadiene emulsions) by >99%, eliminating energy-intensive stripping processes in many cases.
-
Oxygen inhibition effect stabilizes polymerization, improving conversion rates.
-
-
Superior Environmental Profile
-
Zero Formaldehyde: Unlike traditional sulfinates, it produces only salts and CO₂ as byproducts.
-
VOC Reduction: When paired with H₂O₂, avoids VOC emissions (e.g., butanol/acetone from tert-butyl hydroperoxide systems).
-
Non-Yellowing: Enhances whiteness of emulsions and films without post-reaction discoloration.
-
-
Operational Flexibility
-
Works in both post-treatment (residual monomer removal) and main-reaction initiation roles.
-
Low dosage requirement (0.03–0.3%) reduces costs.

Applications
RA-FR06 is ideal for:
-
Post-Treatment: Removing residual monomers in acrylic, VAE, and styrene-butadiene emulsions.
-
Low-Temp Initiation: Enabling energy-efficient polymerization starts at 60–75°C.
-
Sustainable Formulations: Meeting eco-certifications (e.g., LEED, EU Ecolabel) via formaldehyde/VOC-free chemistry.
Handling & Storage
-
Packaging: 25 kg carton box (PE bag inner).
-
Shelf Life: 12 months in original, sealed packaging.
-
Storage: Dry, ventilated area; avoid light, heat, and moisture.
Why Choose RA-FR06 Over FF6M?
RA-FR06 delivers equal or superior reducing performance while addressing critical industry gaps:
-
✅ Eliminates formaldehyde – Aligns with global chemical regulations (REACH, TSCA).
-
✅ Reduces VOC footprint – Critical for indoor-applied polymers (e.g., paints, adhesives).
-
✅ Simplifies production – Removes stripping steps, cutting time/energy costs.
Conclusion
AgeSin® RA-FR06 redefines redox polymerization with its eco-efficient, high-reactivity formula. For industries seeking to replace Bruggolite FF6M without compromising performance, RA-FR06 offers a future-proof solution that prioritizes sustainability, operational efficiency, and end-product quality.
