Product introduction
    Silicone surface additive for slightly reducing surface tension and slightly improving slip in solvent-borne coatings. Good leveling and defoaming; also recommended for room temperature curing plastic systems.

  chemical components  
   Polyether-modified polymethylalkylsiloxane solution.

  Current status of food contact regulations  
     For information on the food contact regulatory status of this product, please contact our Product Safety Department.

 Application: coating industry

  Features and Benefits  
  The additive slightly reduces the surface tension of the coating. It also has defoaming function as a leveling agent, especially suitable for non-polar and medium polar systems. Its defoaming effect increases with increasing polarity. BYK-320 prevents "ghosting" and "telegram" problems. When addressing such issues, additives should be added to coatings that require recoating.

 Recommended use
      This additive is especially recommended for solvent-borne coating systems, but can also be used in water-based systems.

  Recommended dosage  
   0.05-0.6 % Auxiliary dosage (as supplied) is based on the total formulation.
The above recommended dosage is for reference, and the optimal dosage needs to be determined through a series of tests.

  Joining method and processing guidance
       The additive can be added at any stage, including post-addition.

  special reminder
     Unlike ordinary silicone oils, this additive is "user safe". However, before use, a series of tests should be carried out to confirm whether the additive is foam stable, and its recoatability and crater tendency should also be evaluated.

 application  ：Room temperature curing plastic system
