Session 7: Radiation Curing
Water-borne UV curable paints are gaining popularity for floor coating applications. This is particularly true for commercial spaces, where minimizing the cure time to minimize service disruptions is crucial. Most commercially available water-borne UV curable paints are based on acrylic-modified resins, typically polyurethane based, that are dispersed in aqueous media. The UV curing process is enabled by formulating these resins with an appropriate photoinitiator, and using the correct wavelength light source to instigate the radical curing reaction that cross-links the system. Incorporation of a silane bearing a functional group that can participate in this radical curing reaction can help boost performance of the cured paint. In this work, we demonstrate that silyl-(meth)acrylates can be used as additives in these water-borne UV curable paints, and lead to improved properties of the cured paint, such as boosting adhesion and overall durability.
