Acid thickener is used to boost as well as solidify the viscosity of various acid systems such as sulfuric, oxalic, hydrofluoric, phosphoric and citric acid. Offered is a multifunctional material offered with perfume solubilization. It ensures effective thickening, corrosion inhibition and good wetting properties. Acid thickener is functional as an aqueous-based synthetic thickener, offered with high molecular weight polymers. This is offered with an acidic monomer as well as an excellent essential component. Performance of the thickener is based on many properties.
