ACULYN™ 22 RHEOLOGY MODIFIER
ACULYN 22 rheology modifier is an anionic hydrophobically modified alkali-soluble acrylic polymer emulsion (HASE) with unusually high aqueous thickening and stabilizing efficiency. This thickener is a liquid, cold- processable product that instantaneously thickens upon neutralization providing ease of handling and increased manufacturing efficiency. ACULYN 22 is offered at 30% solids and is compatible with high levels of surfactants. The polymer has a well-established toxicological profile and is safe in normal use. Acrylic copolymer.

| Characteristics | The presence of the C18 hydrophobe causes neutralized solutions of ACULYN™ 22 Polymer to be very pseudoplastic, in general showing a high degree of shear thinning because of easily broken van der Waals forces. The yield value also allows the thickener to stabilize suspensions, while still being pourable. The alkaline solutions are clear, and their flow properties are characterized by a complete lack of stringiness and tackiness and by shear thinning. At the same time, the solutions are viscous at low shear rates. Low-viscosity dispersion that becomes a highly viscous clear solution when neutralized with alkali. Thickens instantaneously upon addition of base, allowing rapid preparation of solutions and products. No need for pre-wetting, high shear mixing or long soak times. |
