Cobalt-Free Paint Drier for Waterborne Alkyds

Borchi® OXY-Coat 1101 is a high-performance cobalt-free paint drier for waterborne alkyds that demonstrates excellent drying performance at low-use levels in coatings.

This curing additive for coatings 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.

In June 2022, the U.S. EPA prioritized Cobalt and Cobalt Compounds for risk assessment and possible regulatory reclassification. 

 

Benefits of Waterborne 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 primary cobalt-free solution for waterborne 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. Borchi® OXY-Coat 1101 helps waterborne alkyd coatings achieve waterborne acrylic-level performance.

Our high-performance cobalt-free drying technology works well in 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 also 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.

  • Safety

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