Anti-Skinning Agent for Solvent-Based Alkyds

Ascinin® Anti-Skin 1240 is a MEKO– and oxime-free anti-skinning agent for oxidatively cured solvent-based low VOC coating systems and pigment pastes. This solution helps relieve regulatory concerns surrounding MEKO in Europe, Canada, and other regions.


MEKO-free anti-skins further enhance sustainability when used with Borchi® OXY-Coat cobalt-free high-performance catalysts for solvent-based short, medium, and long oil alkyd coatings or Borchi® Dragon high-performance cobalt-free catalyst for solvent-based high solids, long oil alkyd coatings.


meko free anti skinning agent with high performance cobalt free catalysts for alkyd paints


Combining Ascinin® Anti-Skin 1240 and Borchi® OXY-Coat in a solvent-based high gloss white trim alkyd paint formulation results in lower dry times and yellowing compared to a formulation with MEKO and cobalt alternatives

  • Physical Characteristics

    AppearanceClear, colorless to brown liquid
    ViscosityMax. 45 mPa·s ISO
    3219 (A) (20 °C)
    Density0.86 – 0.90 g/cm3
    DIN 51757 (20 °C)
    SolventFatty acid ester
    SolubilitySoluble in organic solvents such as alcohols, ethers, xylene, white spirit, butyl glycol, printing oils; in water slightly soluble

  • Features

    • Improves the storage stability of solvent-based oxidatively
      cured coating systems, printing inks and pigment pastes by
      preventing skin-formation on the surface of the coating while still in the container
    • Controls surface dry retardation and keeps the film open
      longer to ensure deeper penetration of oxygen to lower film
      layers which promotes through dry and improves flow
    • Can eliminate excessive dry time retardation with phenolics
      or the toxicity of oximic compounds

  • Applications

    • Printing inks
    • Clear or pigmented systems
    • Coatings
      • Solvent-based
      • Solvent-free oxidatively drying
      • High solids paints
      • Environmentally friendly
      • VOC-reduced

  • Dosage

    Ascinin® Anti Skin 1240 can be added to the system in any formulation step. A preliminary dilution is not suggested. We recommend its addition in a final production step after adding the siccatives to the formulation. The required amount of Ascinin® Anti Skin 1240 depends on type of binder and quantity of the used driers. Usual amounts for coating systems based on alkyds are approx. 0.2 to 0.8 % by weight on total formulation. In case of substitution of Butanonoxime we recommend starting with adding half the amount of the substituted Butanonoxime and then optimize the addition rate on basis of the obtained results.

  • Storage

    Protect from the effects of weathering and store at temperatures between 5 and 30 °C in the original container. Once opened, containers should be resealed immediately after each removal of the product.

  • Safety
