Dispersing agent (acidic, solvent-borne) based on Solution of a copolymer with acidic groups (polymeric wetting & dispersing agent), functioning as wets and disperses inorganic pigments — especially titanium dioxide and iron oxide — and stabilizes them in solvent-based mill base in automotive OEM and refinish paint, solvent-based industrial coatings, and coil coating (especially TiO2 systems) formulations. Available in solid content ~52%; acid value ~53 mg koh/g; densitas 20 °c ~1,03 g/cm³; pelarut methoxy propyl acetate / alkylbenzenes 1:1 specification, BASF product, and 20 kg packaging.

Frequently asked questions
What is EFKA FA 4609 AN and what is it used for?
Dispersing agent (acidic, solvent-borne) based on Solution of a copolymer with acidic groups (polymeric wetting & dispersing agent), functioning as wets and disperses inorganic pigments — especially titanium dioxide and iron oxide — and stabilizes them in solvent-based mill base in automotive OEM and refinish paint, solvent-based industrial coatings, and coil coating (especially TiO2 systems) formulations. Available in solid content ~52%; acid value ~53 mg koh/g; densitas 20 °c ~1,03 g/cm³; pelarut methoxy propyl acetate / alkylbenzenes 1:1 specification, BASF product, and 20 kg packaging. EFKA FA 4609 AN is supplied in Indonesia by PT Bahtera Adi Jaya.
What is the recommended dosage for EFKA FA 4609 AN in formulations?
The use level commonly referenced in the product's technical documents is Active on pigment/filler weight: filler & extender 1.5–2.5%; TiO2 3.0–6.0%; other inorganic pigments 3.0–6.0%. 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.
