EBECRYL® 4900 can be combined with NCO-bearing resins for theformulation of UV coatings cured by the dual-cure process (UV-inducedpolymerization and NCO/OH reaction).
After flash-off, radiation cureand/or thermal cure may occur sequentially or concurrently. Either theradiation cure or thermal cure may occur first.
Coatings first subjected toradiation followed by a thermal curing typically may be used for coating 3D parts.
Alternatively, coating that are first thermally crosslinked and further down stream cured with UV radiation allows intermediate processing of the coated articles as used in thermoforming applications.
Deep draw thermoforming coatings can be obtained in combination with NCO functional binder EBECRYL® 4950.
