Product Properties

AFCONA-5010 helps to wet and disperse inorganic pigments, mainly TiO2, and extenders. AFCONA – 5010 is special designed as effective dispersant for TiO2. Therefore, recommended for pure white systems. However, if later the white base need to be tinted with other colors, AFCONA-4010 will be more suitable.

AFCONA – 5010 has below special properties and recommended in below systems:

• AFCONA – 5010 is tailor made as effective dispersant for TiO2 and extenders.
• It has very good viscosity reduction properties. In high extender loaded systems, like UPE in artificial marble, AFCONA 5010 gives very strong viscosity reduction to allow higher filler loading.
• Due to the effective viscosity reduction, it also decreases dispersing time.
• AFCONA-5010 is particularly suitable for the following coating systems: -automotive (OEM and refinish) -general industrial -coil coating -acid curing
• In electrostatic spraying system for pure white paint, AFCONA – 5010 gives the highest gloss performance.

AFCONA-5010 could have a catalyzing effect on the reaction in stoving enamels. This may lead to viscosity increase during storage.

Note: AFCONA – 5010 will become slightly hazy at temperatures below 5° C. This will not influence the quality.

Storage

AFCONA-5010 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.
