COALINE will develop a in-line clean one-stage process, which is free of VOCs and small particles emissions, able to produce properly coated composite pultruded profiles by means of the development of the sensing technology, advanced mould design and microwave aided curing needed to foster an improved composite – coating adhesion with a reduced labor and process cost. COALINE profiles will be joined to other materials by means of a primer type coating, incorporated also in-line, with bonding on-demand properties.
