Water-Based Alkyd 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 compliant. As cobalt is increasingly being labeled as a toxic metal around the world, this product boasts as a curing solution that does not contain any toxic metals.

Benefits of 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 also our only water-based cobalt-free solution. Benefits of this 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 solutions are able to be used in water-based exterior alkyd coatings used in extreme weather conditions. This extends the coatings season window for paint applications. It also provides wrinkle-free drying in hot weather.

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

    • 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.
