Frequently asked questions
What is Rheovis HS 1181 AM and what is it used for?
Rheology modifier (HASE associative thickener) based on Aqueous dispersion of acrylic copolymer with hydrophobic groups (HASE - hydrophobically modified alkali-soluble emulsion), functioning as a HASE associative thickener for water-based acrylic coating systems in water-based acrylic paint, styrene-acrylic systems, and waterborne coatings formulations. Available in Solids content 29-31%; pH 4.5-5.5; Brookfield RVT 1/20 viscosity 5-50 mPa.s specification. Rheovis HS 1181 AM is supplied in Indonesia by PT Bahtera Adi Jaya.
What is the recommended dosage for Rheovis HS 1181 AM in formulations?
The use level commonly referenced in the product's technical documents is Can be added as a pre-gel (85% water : 15% Rheovis HS 1181 AM) or directly to the dispersion; the medium must be alkaline, recommended system pH 8.5-9.0. 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.
