Cobalt-Free Paint Drier for Water-Based Alkyds

Borchi® OXY-Coat 1101 is a high-performance cobalt-free paint drier for water-based alkyds 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 benefits the market as a waterborne curing solution that does not contain metals like cobalt that could potentially compromise sustainability in coating applications.


Benefits of Water-Based High-Performance Cobalt-Free Driers

Borchi® OXY-Coat 1101 is a high-performance catalyst that is applicable in coating systems that dry oxidatively. It is our only cobalt-free solution for water-based alkyd coatings that is available in all regions. Benefits of this cobalt-free paint drier include improved dry times, gloss, and haze. This solution also provides brighter whites and lower yellow tones in coatings.

Our high-performance cobalt-free drying technology is ideal for waterborne exterior alkyd coatings used in extreme weather conditions. This helps extend the coatings season window for outdoor paint applications. It provides wrinkle-free drying in hot weather and improves dry times in low temperature, high humidity weather.

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

  • 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.
