Water-Based Alkyd Cobalt-Free Paint Drier

Borchi® OXY-Coat 1101 is a cobalt-free water-based alkyd paint drier that demonstrates excellent drying performance at low use levels in coatings.

This curing additive is not only cobalt-free, but also VOC-free, APEO-free, and Proposition 65 and REACH compliant. As concerns around cobalt are increasing within the coatings industry, this product boasts as a waterborne curing solution that does not contain any potentially toxic metals.

Benefits of Waterborne Cobalt-Free Driers

Borchi® OXY-Coat 1101 is a unique catalyst that is applicable in a wide range of coating systems that dry oxidatively. It is our only water-based cobalt-free solution. Benefits of this waterborne cobalt-free paint drier include improved dry times, gloss, and haze. This solution also provides brighter whites and non-yellowing properties in coatings.

Our cobalt-free drying technology is ideal for water-based exterior alkyd coatings used in extreme weather conditions. This helps extend the coatings season window for outdoor paint applications. It also provides wrinkle-free drying in hot weather, resulting in smooth substrate surfaces.

Improved loss of dry over stability and better adhesion in direct to metal applications are also provided by our cobalt-free drying solutions.

Cobalt-free driers prevent wrinkling in water-based alkyd paints compared to cobalt containing driers


cobalt-free / cobalt replacement driers are sustainable alternatives to cobalt driers in alkyds. Cobalt paint driers are facing strict sustainability, regulatory, and ethical challenges (cobalt may soon be a conflict mineral)

Applications include wood, industrial, and architectural coatings, as well as printing inks.

  • Applications

    • Coatings with binders that dry by oxidation

  • Dosage

    All resin systems are unique and will require the level of Borchi® OXY - Coat 1101 to be optimized for the best cost and dry. We recommend using a ladder study of 0.25 – 2 % Borchi® OXY - Coat 1101 as supplied on resin solids. Please keep in mind that too much Borchi®  OXY - Coat 1101 might inhibit through dry. Borchi® OXY - Coat 1101 should be added as one of the last ingredients before the Anti-Skinning agent.

  • Storage

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

  • Safety

    Please refer to our safety data sheet for information relating to product safety.
