Global Optimals’ Acrylic Thickener K 28/29 is a high‑performance HASE/ASE polymer designed to control the rheology of waterborne paints. With a pH > 7.5 it forms a stable emulsion, and a dosage range of 0.3‑1.5 % provides the desired viscosity without compromising film properties. The thickener delivers a pronounced thixotropic effect: at low shear rates the paint remains fluid, while under high shear it instantly thickens, facilitating easy application and reducing sagging. It is widely used in interior wall paints, ceiling coatings, and putties where high abrasion resistance and a uniform finish are required. The polymer belongs to the class of hydrophobically modified associative thickeners (HASE) and contains long acrylic chains bearing ionic groups that, in alkaline media, self‑associate into micro‑gel networks. These networks trap pigment and filler particles, improving dispersion stability and preventing sedimentation. K 28/29 is compatible with typical waterborne formulation ingredients such as acrylic and vinyl binders, dispersants, antifoam agents, and a range of surfactants, making it suitable for high‑solid exterior coatings, metal and concrete paints, as well as decorative plasters and joint compounds. During formulation the thickener is usually added to the water phase under moderate agitation (≈200 rpm) before the addition of pigments and binders; a small amount of alkaline adjuster (e.g., NaOH) may be used to keep pH above 7.5 and ensure full polymer activation. Recommended storage is a dry, cool area at +5…+30 °C, protected from direct sunlight and moisture. Packaging in 25 kg bags with hermetic film simplifies logistics across Uzbekistan, Kazakhstan and Russia. The high purity and absence of free monomers eliminate odorous volatiles and enhance adhesion to a variety of substrates. Proper mixing yields a bubble‑free, homogeneous coating, improving the aesthetic quality of the final film. In formulations with high solid content the thickener reduces solvent demand, contributing to a better environmental profile. Additionally, the associative network promotes more uniform film formation, often shortening drying time in multi‑coat applications.

The Acrylic Thickener K 28/29 should be stored in a dry, well‑ventilated area at ambient temperatures, typically between +5 °C and +25 °C, protected from direct sunlight and moisture. When stored under these conditions the product remains stable for 12–24 months, but it is advisable to use it within 6 months after opening. During handling wear protective gloves and safety glasses, and avoid skin and eye contact. Ensure the container is tightly sealed; any damaged packaging must be replaced to prevent moisture ingress and contamination.
