  ERDISPER 28000 polymer dispersant is applied for the general industrial paint, gravure printing ink, soluble in ester, ketone and aromatic hydrocarbon solvent. It helps organic pigment and carbon black dispersing in the ink by grinding process. It is compatible to lots of kinds of resins and solvents. It can dramatically improve pigment dispersion in combination with exact dispersant. Chemical composition: Polymers segmented copolymer with group Technical Index: Items Properties Appearance Brown Viscous liquid Effective active components % 100% Density （20℃） g/ml 0.95 Boiling point ℃ ＞300 Flash point ℃ About 220 Characteristic: Improve the concentration of the pigment Significantly preventing solid particles sediment, agglomeration. Improve wetting properties of the pigment Improve color tinting strength Improve stability of low resin content system Application: Apply to resin system:alkyd resins acrylic resin NC nitrocotton amino [amine] resin epoxy resin polyurethane and so on automobile coating industrial paint Packaging gravure ink Application guide : Charging procedure: solvent, dispersant, resin, pigment, keep gently agitation during charging process. High speed stirring for 20-30 minutes, then grinding by the wet-mill. Every color has a specific surface area, dispersant dosage is different accoirdingly. In general, dispersant dosage is equivalent to pigment surface area /5 (percentage of pigment dosage) Packaging and storage : 25kg/iron drum Under Sealing conditions, store in a cool, ventilated place.
