What is Borchi ® OXY-Coat?

� Targeted Molecule originally designed fordetergent use

� OMG identified and transferred technologyto coatings applications

� Unique Catalyst for Alkyd Coatings� Unique Catalyst for Alkyd Coatings

� Iron-based catalyst (1.0% solution inpropylene glycol)

� Applicable in a wide range of oxidativelydried systems


Borchi ® OXY-Coat Performance Advantages

� Shortens dry time in high solid and waterborne systems

� Eliminates need for cobalt and minimizes dependency on through

driers

� Improves loss of dry � Improves loss of dry

� Excellent performance in adverse conditions

� Excellent color and yellowing stability over cobalt-based systems

� Eliminates price volatility

Borchi ® OXY-Coat Performance Advantages

� Shortens dry time in a wide range of coatings

� No need for cobalt and minimum dependence on through driers

� Improves loss of dry

� Excellent performance under adverse conditions

� Excellent color and yellowing stability


Suggested Borchi ® OXY-Coat Use

� Use in all solvent and waterborne coating systems to catalyze cross-linking

� Use 0.5% to 3% of Borchi® OXY-Coat additive on Resin solids

� 0.5-1% for WB, SO-MO alkyds (No secondary driers)

� 1-3% for MO-LO, highly extended (Use with secondary driers)

� MEKO alternatives - Ascinin® 0444 and 0445

� Thickeners - Borchi® Gel 0434 and 062x series

� Wetting & Dispersing - Borchi® Gen 0451, 0650, and 0755


The Future?

In Europe, cobalt carboxylates will likely be reclassified under REACH

�With cobalt reclassification under REACH, what is the future for the United States (is cobalt the next lead)?

� Are manganese driers the future?

� Can we live without alkyd coating systems?

� What real alternatives are available in the marketplace?

� Are you interested in an alternative that has additional performance benefits?
