Borchi® OXY-Coat is a metal-based cobalt-free drier that demonstrates excellent drying performance at low use levels in solvent-based alkyd coatings, particularly those using propylene glycol.

This solution is a unique catalyst that is applicable in a wide range of coating systems that dry oxidatively. As cobalt is increasingly being labeled as a toxic metal around the world, Borchi® OXY-Coat boasts as a curing solution that does not contain any toxic metals.

Benefits of this cobalt-free drier include faster dry times, improved gloss and haze, brighter whites, non-yellowing and the ability to be used in adverse conditions thus extending the coatings season window.

Applications include wood, industrial and architectural coatings, as well as printing inks.

  • Applications

    • Coatings with resins that that dry by oxidation 
      • Alkyds 
      • Vegetable oils
      • Epoxy esters
      • Polybutadiene 
      • Others 

  • 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.
