UV curable waterborne coatings based on acrylate functional polyurethane dispersions (UV PUDs) have found acceptance in the wood and resilient flooring markets, but the performance of waterborne UV technology may offer potential for other markets as well. The performance of waterborne coatings based on UV PUDs was evaluated by testing the properties of adhesion, impact resistance, flexibility, hardness, solvent resistance and corrosion resistance when applied to aluminum and steel substrates. For comparison, the performance of coatings based on selected 100% solids acrylate functional oligomers was also tested.
