AFCONA 7525
AFCONA 7525 is a block polymer with acidic functionality and viscosity-depressing properties. It is recommended for use in unsaturated polyester, PVC, epoxy, and polyurethane resin systems and is primarily used as a wetting and dispersing agent in highly filled systems, providing strong viscosity-depressing properties. It has excellent wetting and dispersing properties with pigments and functional fillers such as ATH, resulting in very low viscosity.

- 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.
- 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
- Storage Information
AFCONA-7525 should be stored in a cool dry place. When kept in an original unopened container, it will keep up to 5 years from the date of manufacture. The expiry date is indicated on the container.
