One-stop Help For Your Production Of White Latex | JCT Machinery

June 10, 2025
  • Q
    What is white latex?
    White latex, also known as PVAc, is a water-based emulsion made by the emulsion polymerization of vinyl acetate (VAc).
    The film formed after curing has good bonding strength and flexibility, and is a commonly used adhesive in woodworking, paper products, textiles and other industries.

** PVA itself is not an adhesive, but it is a protective colloid for PVAc emulsion. PVA is often added to stabilize the emulsion during the synthesis of white latex.

8. Water pump, water tower


White Latex Production Process
1. Use a high shear stirring system to emulsify vinyl acetate monomer.
2. Polymerize with a free radical initiator (such as ammonium persulfate).
3. Control the temperature at 70~85℃ during the reaction.
4. After the reaction is completed, cool and filter to finally obtain a stable milky white emulsion, i.e. white latex.
