Frequently asked questions
What is Dispex Ultra PX 4585 and what is it used for?
Dispersing agent (waterborne, VOC-free) based on Acrylic block copolymer (controlled free radical polymerization), functioning as a dispersing agent for resin-free water-based pigment concentrate in resin-free/minimal-resin pigment concentrate, water-based decorative paint, and water-based industrial paint formulations. Available in Active ingredients ~50%; water solvent; VOC-free; amine value ~20 mg KOH/g; color ≤ 9 specification. Dispex Ultra PX 4585 is supplied in Indonesia by PT Bahtera Adi Jaya.
What is the recommended dosage for Dispex Ultra PX 4585 in formulations?
The use level commonly referenced in the product's technical documents is Pigment-dependent; BASF's reference formulation uses 5.5-22.0% Dispex Ultra 4585 in the pigment concentrate. The final dosage still depends on the formulation system, so small-scale trials are recommended before mass production.
Are COA, MSDS, and technical support documentation available?
Yes. Every shipment is accompanied by a Certificate of Analysis (COA) and Material Safety Data Sheet (MSDS/SDS) matching the production batch. For other regulatory documents (e.g. halal certification or special specifications), please contact our sales team.
