Cobalt-Free Drier 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 do not contain metals like cobalt that may face regulatory concerns in coating applications. Borchi® OXY-Coat is particularly efficient in coatings using propylene glycol.

 

 

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 potential regulations surrounding cobalt in coating applications. For example, in June 2022, the U.S. EPA prioritized Cobalt and Cobalt Compounds for risk assessment and possible regulatory reclassification. 

 

Performance benefits of Borchi® OXY-Coat include improved drying time, wrinkling prevention, and corrosion resistance in alkyd-based paint. This solution also provides brighter whites and reduces yellowing in coatings. Adhesion is improved in direct-to-metal applications with the use of this product. Borchi® OXY-Coat can also eliminate or reduce 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.

 

 

faster dry times in adverse conditions with high performance catalysts

 

Compared to cobalt carboxylate driers, cobalt-free paint driers allow for the use of exterior coatings in standard and adverse conditions. They provide improved dry times in low temperature, high humidity weather

 

 

non yellowing of alkyds with cobalt free drier

 

Color advantages include brighter whites in coatings compared to cobalt

 

 

wrinkling prevention from over-application due to cobalt-free water-based alkyd drier

 

Compared to cobalt alternatives, Borchi® OXY-Coat prevents wrinkling, creating a smooth appearance

 

 

improved corrosion resistance with cobalt free drier for alkyds

 

Borchi® OXY-Coat can help inhibit corrosion better than cobalt alternatives in direct-to-metal alkyd coating applications

 

 

better wet adhesion with cobalt free driers

Borchi® OXY-Coat can provide excellent wet adhesion in direct-to-metal alkyd coating applications

 

 

Similar Cobalt-Free Driers

While Borchi® OXY-Coat can work in water- and solvent-based systems, it tends to work best in solvent-based alkyd systems. Borchi® OXY-Coat 1101 is ideal for water-based alkyd coatings. Borchi® Dragon is designed for use in high solids alkyds.

 

Use with Oxime-Free Anti-Skins

When anti-skins are needed in an alkyd formulation, Borchi® OXY-Coat can be used with Ascinin® oxime-free anti-skins to enable enhanced skin prevention, storage stability, and minimal effect on dry times in alkyd coatings. With oximes also facing regulatory scrutiny, this combination can help improve product labeling.

 

Applications

Ideal applications for Borchi® OXY-Coat include wood, industrial, and architectural coatings, as well as printing inks.

  • Dosage

    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. 

  • 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.
