Product Overview: DISPEX AA4141 is part of BASF's line of high-efficiency water-based coating dispersants, ideal for dispersion of inorder pigments. Sodium acrylic salt water solution.features: Excellent dispersion High solidity with typical physical properties, appearance; light yellow liquid solid content: 45% 25 degrees C dynamic viscosity (Brookfield 20rpm): 500-1500mPa.s pH: 7.0-9.9 0
(typical physical characteristics are reference materials for product physical data provided by suppliers to users or potential users and should not be used as testing standards for product qualification or failure; detection indicators and methods refer to product inspection reports and product indicators file)The scope of application
DISPEX AA4141 has ideal dispersive stability in a wide range of water-based coating systems.
pH range of 5-12 for DISPEX AA4141, and the temperature remains dispersed even at temperatures of 100 degrees C.Use Method
recommends adding pigment powders to water that already contains DISPEX AA4141 dispersants under rapid stirring, instead of adding DISPEX AA4141 dispersants to the pigment slurry, which is usually best at 8.5 pH.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 the cost rise, the same, insufficient dosage will lead to a decline in storage stability and similar dispersants, due to the quality performance fluctuations between the batch of pigments and latex, the actual formulation amount is recommended for the theoretical best dosage of 1.5-2 times..
