DISPEX AA4140 AS has an ideal dispersion and stability effect in a wide range of water-based coating systems.
the pH range of the DISPEX AA4140 AS is 5-12, and the temperature remains dispersed even at 100 degrees C.Use Method
recommends adding pigment powders to water that already contains DISPEX AA4140 AS dispersants in a quick mixing situation, instead of adding DISPEX AA4140 AS dispersants to the pigment slurry, usually with a pH of 8.5.the amountdosage
dispersant dosage depends to a large extent on the chemical composition of the pigment, the nature and shape of the particle surface, but also closely related to the type of latex, serious overuse will damage some of the properties of the coating, and make costs rise, the same, insufficient dosage will lead to a decline in storage stability and similar dispersants, due to the quality performance fluctuations between the pigments and latex of each batch, the actual formulation dosage is recommended for the theoretical best dosage of 1.5-2 times..
