Photo-curable resins based on multifunctional acrylate monomers are commonly applied as thin films (e.g. protective coatings, printing inks, etc.) and in recent years are also used for the fabrication of bulk objects such as dental fillings and 3D-printed parts.
A new polymer on the basis of a trick used by mussels has been developed by the Wageningen PhD student Juan Yang. The polymer should be able to let water-based paint flow better and produce water resistant coatings.
Bio-based polyurethane (PU) coatings have been used extensively from last few decades and replaced petrochemical based coating due to their lower environmental impact, easy availability, low cost and biodegradability.
