HALOX® presents its abstract at the SSCT's upcoming meeting in Atlanta, GA

On April 19, 2012, Nathan Kofira, Technical Development Manager at HALOX®, presented his abstract: “Tannin Stain Inhibition” at the Southern Society for Coatings Technology meeting in Atlanta, GA.

The advent of water-based resins for the architectural market have paved the way for new challenges associated with coating wood substrates. Wood is prone to rotting, warping, cracking, peeling and growing microorganisms. Oil and water soluble wood extracts such as tannic acids are a problem for water-based paints. Customers applying water-based paints to wood know firsthand that water brings (“bleeds”) out the soluble stains to the topcoat and causes the paint to discolor and look unsightly. Tannin stain blocking additives were developed to augment resin technology in stopping the migration of these soluble stains to the surface of the paint. Several technologies were developed to provide this chelation mechanism using multi-valent cations or sol-gel film forming technology.

Nathan Kofira has spent over 10 years performing industrial research on acrylic polymers and additives implicit to coatings formulation. The use of additives to combat tannin staining across the ever changing sourcing landscape involves a blend of creativity and technical understanding. Upon joining HALOX, Nathan is committed to providing a creative approach to both tannin stain and corrosion inhibition which maximizes the synergy of select inhibitors and promoting the underlying modes of action involved.
