Borchi^® Dragon

High-Performance Paint Catalyst for High Solids Alkyd Resins

Borchi^® Dragon is a high-performance, organometallic ligand paint catalyst for systems containing high solids, long oil alkyd resins. This solution is cobalt-free.    

Importance of Low VOCs and Cobalt-Free Driers in High Solids Alkyd Coatings

Regulations are becoming increasingly stringent for coatings around the world. According to the Cobalt Institute, cobalt toxicity is being questioned by regulatory agencies around the world. For example, the U.S. EPA has prioritized Cobalt and Cobalt Compounds for risk assessment and possible regulatory reclassification. This metal is often used as a paint catalyst and drier. As Borchi^® Dragon is designed to be cobalt-free, this paint catalyst provides performance benefits and can help future-proof against cobalt regulatory scrutiny compared to metal carboxylate alternatives. VOCs have been a concern for some time in household products such as paint.      

Borchi^® Dragon Low VOC is a cobalt-free high-performance catalyst option that only contains 2% VOC content (ASTM D2369) for solventborne and solvent-free alkyd formulations.

     

Benefits of High-Performance Catalysts for High Solids Paints

Borchi^® Dragon provides a wide range of performance benefits in paints. These include faster dry times, non-yellowing performance, complexity reduction, and storage stability. This product requires minimum dependency on through driers. Hardness is comparable to cobalt-containing solutions. Borchi^® Dragon works well in both standard and adverse conditions. It extends coatings season windows and prevents wrinkling from over-application in hot weather.  

Applications

Borchi^® Dragon is ideal for use in architectural, wood, and general industrial end-use applications. In high solids white enamel architectural coatings, Borchi^® Dragon provides brighter whites and enhanced through dry performance compared to cobalt.

Borchi^® Dragon provides brighter and cleaner whites compared to cobalt-containing catalysts in high gloss white enamels

   

Through Dry Time Comparison Under Standard and Adverse Conditions

0.5% Borchi^® Dragon provides better through dry times in standard and adverse conditions compared to cobalt-containing and alternative cobalt-free catalysts in high gloss white enamels

    When used in clear standard varnish wood finishes, Borchi^® Dragon prevents thick film build. It also prevents the coating from turning yellow over time.

Wrinkling from over-application is prevented with the use of Borchi^® Dragon

   

     Yellow Value (b*)

Non-yellowing in clear varnishes is enhanced with the use of 1% Borchi^® Dragon compared to cobalt-containing catalysts

        Borchi^® Dragon also provides outstanding wet adhesion, corrosion resistance, and dry times in high gloss black direct-to-metal (DTM) industrial coatings.
