BIO

Dr. Sheba D. Bergman obtained her PhD in Chemistry from Tel Aviv University in 2005. She was a Rotschild post-doctoral fellow in Prof. Buchwald’s group at MIT and a post-doctoral associate in Prof. Wudl’s group at UCSB. She worked on a collaborative project between Janssen Pharmaceutica and the University of Antwerp in Belgium, and worked for L’Oreal's R&D for three years in France. She worked on nail enamel product development at Revlon. She joined the functional silanes applied technology team at Evonik in 2014, providing technical and application support to customers in the NAFTA region.
 

ABSTRACT

Acrylic emulsions are extensively used as film-forming resins in water-borne latex paints for interior and exterior architectural applications. Acrylic emulsions are typically synthesized via a radical emulsion polymerization process, where a mixture of different acrylic- and/or methacrylic-based monomers are used to tailor the final properties of the resin. In our work, we utilize silane-modified acrylic monomers, or silyl-acrylates, as co-monomers in the synthesis of acrylic emulsions to generate silane-modified acrylic emulsions. These silane-modified acrylic emulsions are stable and are easily incorporated into a water-borne architectural paint formulation. The incorporation of a silane into the backbone of the acrylic emulsion at low levels (2 %w/w) provides improved adhesion, durability and weathering performance. In particular, the silane-modified acrylic emulsion based paints exhibit outstanding adhesion to wet concrete with no bubbling on the surface and no delamination, even after prolonged immersion in water. This outstanding adhesion to wet concrete could withstand pipe leaks and flooding from heavy rain and natural disasters that are increasingly on the rise. This represents a very affordable method for prolonging paint service life under extreme wet conditions and reducing costs associated with removing delaminated paint and repainting.
