Modified approach of coating a resin during the curing process.
Gel time, during which the material partially crosslinks and maintains form, and full cure time, during which the chemistry completes and characteristics stable, are the two stages of curing for most liquid resins. To functionalize the surface of the cured resin with a coating, another step is required.
Rutgers researcher has developed a simple method by which surface functionalization is completed during the curing step of polymer composites. It involves first gelling a 2-part curing resin followed by immersing in a material that can react with the curing chemicals at the surface, therefore producing a monolayer coating on the surface of the resin. This process has been tested on 3D-printed objects cured with acrylic and epoxy chemistry.
