The key to achieving a perfect fusion of rosin and water is to choose the right emulsifier. It is recommended to use anionic and non-ionic emulsifiers, such as AES+APEO. After mixing in proportion, slowly add molten rosin, then add hot water under high-speed stirring, and instantly turn into delicate lotion! Remember to control the temperature between 90-100 ℃, stir slowly and then quickly, and finally cool down to below 38 ℃. The rosin lotion made in this way can not only be stable and stored for a long time, but also be used for paper sizing and coating thickening!
