Frequently asked questions
What is EFKA PX 4330 and what is it used for?
Dispersing agent (high-molecular-weight block copolymer, solvent-borne) based on Acrylic block copolymer (dibuat dengan Controlled Free Radical Polymerization / CFRP), functioning as stabilizes pigments in solvent-based coating systems, especially for producing pigment concentrates with minimal resin in resin-containing pigment concentrate (RCPC), solvent-based decorative (alkyd) paint, and solvent-based industrial coating (2K PUR, 2K acrylic, NC, epoxy) formulations. Available in Active ingredients ~70%; amine value ~29 mg KOH/g; density 20°C ~1.03 g/cm³; solvent 1-methoxy-2-propyl acetate; color ≤ 9 specification, BASF product, and 20 kg packaging. EFKA PX 4330 is supplied in Indonesia by PT Bahtera Adi Jaya.
What is the recommended dosage for EFKA PX 4330 in formulations?
The use level commonly referenced in the product's technical documents is The TDS guideline formulation uses ~2.2–9.0% Efka PX 4330 in resin-containing pigment concentrate (depending on pigment type); a ladder study is required for specific formulations. 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.
