Product Properties

AFCONA-5266 is the solvent free version of AFCONA - 5066, and it may be used in the same applications. It can also be post-added to solve flooding and floating problems. In combination with a suitable high molecular weight dispersant, AFCONA - 5266 can be used as a co-grinding agent. AFCONA – 5266 has the following special properties:

• The performance of AFCONA - 5266 is almost identical to that of AFCONA – 5066. However, AFCONA – 5266 does not contain any solvent so dosing should be adjusted accordingly based upon active content. AFCONA-5266, like AFCONA - 5066 may be preferable in many foam sensitive systems such coil coatings, floor coatings and those coatings applied by curtain coater.
• If some polysiloxane is needed in the grinding phase to improve wetting and increase grinding speed, AFCONA polysiloxanes such as AFCONA – 3236, AFCONA – 3238 and AFCONA – 3239 are recommended.
• AFCONA - 5266 is especially suitable for medium to high-polarity binder systems like: - alkyd/amino resin combinations - nitrocellulose systems - polyurethane systems - acrylic polyisocyanate systems (2 - pack acrylics) - chlorinated polymers
• AFCONA - 5266 is not compatible with white spirit or paints which are diluted with white spirit.

Note: AFCONA – 5266 will become slightly hazy at temperatures below 5° C. This will not influence the performance of the product.
