Cobalt-Free Drier / Sustainable Solution for Improved Dry Time in Alkyd Paint
Borchi® OXY-Coat is a metal-based high performance cobalt-free drier catalyst for improved drying time in paints containing alkyd resins. It demonstrates excellent drying performance at low use levels in solvent-based short, medium, and long oil alkyd paint. This solution does not require the use of an auxiliary drier. Cobalt-free driers are eco-friendly drying solutions as they do not contain any metals that may face regulatory concerns. Borchi® OXY-Coat is particularly efficient in coatings using propylene glycol.

Comparison of Borchi® OXY-Coat in Medium Oil Alkyd Paint
Borchi® OXY-Coat provides improved drying time compared to a cobalt drier in medium oil alkyd paint. This oxidative curing catalyst also works well in short and long oil alkyd systems
How does alkyd paint dry?
Coatings typically need a metal catalyst to achieve the best dry times. As a high performance metal-based catalyst, Borchi® OXY-Coat is applicable in a wide range of alkyd coating systems that dry oxidatively.
Benefits of High Performance Cobalt-Free Driers
Cobalt-free paint driers are ideal long-term solutions for formulators looking to meet stringent environmental regulations.
Due to environmental concerns with cobalt catalysts within the coatings industry, Borchi® OXY-Coat is a great environmentally sustainable alternative curing solution that does not contain any questionable metals. It also allows for low amounts of Volatile Organic Compounds (VOCs) in formulations and is compliant with Proposition 65 and REACH guidelines.
Performance benefits of Borchi® OXY-Coat include improved drying time, gloss, and haze in alkyd-based paint. This solution also provides brighter whites and acts as an anti-yellowing agent in coatings. Adhesion is improved in direct to metal applications with the use of this product. Borchi® OXY-Coat eliminates or reduces the need for anti-skinning agents.
Borchi® OXY-Coat works well for exterior coatings used in adverse weather conditions. This extends the coatings season window for paint applications. It provides wrinkle-free drying in hot weather and faster drying in cold weather.
Non-Yellowing of Alkyds Over Time
Cobalt Drier Borchi® OXY-Coat
Color advantages include the non-yellowing of substrates and brighter whites in coatings compared to cobalt and other metal carboxylates
Manganese Drier Borchi® OXY-Coat
Yellower Wood Tones Warmer Wood Tones
Borchi® OXY-Coat provides warmer wood tones compared to manganese driers, which tend to cause yellowing in wood coatings
Borchi® OXY-Coat Advantage Under Adverse
(10ºC / 80% RH) Conditions in Different Systems
Compared to cobalt carboxylate driers, cobalt-free paint driers allow for the use of exterior coatings in adverse conditions. They provide improved dry times in low temperature, high humidity weather
Wrinkling Prevention on Substrates
Cobalt Drier Borchi® OXY-Coat
Unlike cobalt alternatives, Borchi® OXY-Coat prevents wrinkling, creating a smooth appearance
Through Dry Time of SB Pigmented Direct to Metal Applications
Cobalt replacement driers are better than cobalt driers in direct to metal applications when used in standard and adverse conditions
Control Borchi® OXY-Coat
Borchi® OXY-Coat reduces or eliminates the need for anti-skinning agents in coatings
Similar Cobalt-Free Driers
While Borchi® OXY-Coat can work in water- and solvent-based systems, it tends to work best for solvent-based alkyds. Borchi® OXY-Coat 1101 is ideal for water-based alkyd coatings. Borchi® Dragon is designed for use in high solids alkyds. Please contact our technical service team for more information.
Ideal applications for Borchi® OXY-Coat include wood, industrial, and architectural coatings, as well as printing inks.

All resin systems are unique and will require the level of Borchi® OXY - Coat to be optimized for the best cost and dry. We recommend using a ladder study of 0.5 -3 % Borchi® OXY - Coat as supplied on resin solids. Please keep in mind that too much Borchi® OXY – Coat might inhibit through dry. Borchi® OXY - Coat should be added as one of the last ingredients before the Anti-Skinning agent.
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.
