Features & Benefits
- Materials Features
- Product Properties
- AFCONA-7525 is recommended for unsaturated polyester, PVC, epoxy, and polyurethane resin systems. AFCONA-7525 main application is as a wetting and dispersing agent in highly filled systems, with very high viscosity depressing properties. It has very good wetting and dispersing properties with pigments as well as functional fillers, such as ATH, to achieve very low viscosity.
- In comparison to other wetting and dispersing agents, AFCONA-7525 performs better in anti-floating & flooding in low viscosity environments. Due to its high acidic functionality, AFCONA - 7525 also can be used in BMC systems as a viscosity stabilizer.
- Note: AFCONA-7525 may become slightly hazy at temperatures below 5° C. This will not impact the performance or quality of the product.
Applications & Uses

- Compatible Reinforcements
- Addition and Dosage
- Pigments/filler dispersant:0.5 - 5.0% based on pigment/filler weight
- Viscosity stabilizer:0.2 – 1.0% based on resin weight
- Incorporation
AFCONA-7525 should be incorporated in the mill base before adding pigments. However, if used after grinding, please apply high shear force to disperse the system.
