Frequently asked questions
What is Rheovis AS 1125 AJ and what is it used for?
Rheology modifier (ASE acrylic thickener) based on Aqueous acrylic polymer dispersion (alkali-swellable emulsion, ASE thickener), functioning as an acrylic (ASE) thickener with pseudoplastic flow behavior at low shear in water-based paints and coatings, and waterborne dispersion systems formulations. Available in Solids content ~25%; pH ~2.8; viscosity <=10 mPa.s (23°C, 250 1/s) specification, BASF product, and 150 kg packaging. Rheovis AS 1125 AJ is supplied in Indonesia by PT Bahtera Adi Jaya.
What is the recommended dosage for Rheovis AS 1125 AJ in formulations?
The use level commonly referenced in the product's technical documents is 1-3.5% of the total formulation. 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.
