The Urea Formaldehyde (UF) technology provided by SL TEC is based on the traditional alkali-acid-alkali process. It consists of three steps: Hydroxymethylation--under neutral or slight alkali conditions, urea and formaldehyde have hydroxymethylation reaction; Polycondensation-- condition the pH of the reaction solution to slight acid, the reaction mixture have polycondensation to reach a certain molecular weight; Temperature Reducing--condition the pH of the reaction solution back to slight alkali, and reduce its temperature to room temp. to get the preliminary condensed solution.
