Afcona 3231

Organically modified Polyether Polysiloxane

AFCONA-3231 can be added at any stage during the production process.

0.05 – 0.50% on total formulation. In general under normal conditions, the dosage is 0.05 – 0.25% based on total formulation.

AFCONA-3231 gives very good slip and the slip characteristic is oily type, also called as wet look appearance. Therefore, it can enhance visually film thickness AFCONA – 3231 normally used in metal coatings like industrial baking systems, car refinish polyurethane top clear coats and other vehicle paint. AFCONA – 3231 also widely used in UV coatings due to the good leveling and slip performance. However, it does not contain any reactive functional group that can cross-link with UV resin system. Due to its high surface activity, AFCONA-3231 can interfere with intercoat adhesion when recoated without sanding. If air is introduced by the application equipment, the use of small amounts of defoamers such as AFCONA-2020 and AFCONA-2022 are recommended.

AFCONA – 3231 is recommended in below systems:
1) 2K Polyurethane. It gives low sensitivity to inner bubble.
2) Industrial baking systems where baking temperature is less than 170ºC. In normal case, AFCONA – 3030 or AFCONA - 3233 is recommended for industrial baking systems. However, if higher slip is needed, AFCONA -3231 will be the better choice.
3) UV coatings. A lot of time, AFCONA – 3231 is selected for UV due to the less foam stabilizing effect and good compatibility.

AFCONA-3231 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
