Afcona 2503

Anti-Cratering , Good Leveling, High Performance, High Shear Applications

AFCONA-2503 can be added at any stage during production process.

AFCONA-2503 should be stored in a cool and dry place. When kept in an original unopened container, it will keep up for 5 years from the date of manufacture. The expiry date is indicated on the container.

AFCONA- 2503 is an organically modified polysiloxane which designed to give good defoamer, anti-foam and leveling performances in all water based coating. It has very low sensitivity to formation of craters to the coating. AFCONA – 2503 have below performance and properties: 1 ) It has very good performance in high shear application. Under high shear environment such as long period of grinding, it still can maintain it good defoaming and anti-foam performance. Thus very suitable to use as defoamer in pigment concentration preparation and high speed flexo printing process. 2) It also effective as defoamer in normally coating ranging from PU dispersion to normal acrylic based decorative paint. 3) Beside good defoaming and anti-foam properties, it also has good leveling performance. Most defoaming available in the market will affect the leveling property of a coating and leveling agent will gives more foam formation to the coating. Thus Afcona 2503 serve as perfect product as it works as defoamer, also gives leveling property. 4) Due to the leveling property, it also will not give crater formation to the coating, another perfect performance that most coating formulators dreaming of to have.

0.05 – 1.00% on total formulation. In general under normal conditions, the dosage is 0.05 – 0.25% based on total formulation. In pigment paste preparation, normal dosage will be ranging from 0.5 to 1.0%.
