Suggest

 The recommended usage is 0.2 ~ 1.0 wt%

 Spread the polymer evenly in the medium while stirring, but avoid agglomeration, stir well to disperse

 Neutralization to pH 5.0 ~ 10 polymer has ideal thickening performance; in a system with hydroalcohol, the neutralizer should be selected correctly;

 After neutralization, avoid high-speed shearing or stirring to reduce viscosity loss
