PAC LV, or low viscosity polyanionic cellulose, is a widely used additive in the coatings industry. Its primary function is as a rheology modifier and thickener for water-based coatings. Due to its high molecular weight and anionic nature, it is highly effective at improving the flow properties of coatings and reducing sagging or dripping during application. In addition, PAC LV can improve the stability and color development of coatings while also enhancing their adhesion to various substrates. Overall, the use of PAC LV in coatings formulations has been shown to result in superior performance characteristics and improved overall quality of the final coating product.
