EBECRYL® 4900 is a tin-free aliphatic hydroxyl-functional urethane acrylate oligomer thoughtfully diluted in 40% butyl acetate. When paired with NCO functional compounds like EBECRYL® 4950, it proves to be exceptionally well-suited for deep-draw thermoformable coatings, exhibiting high elongation properties post-thermal curing and subsequent UV curing. Its outstanding performance extends to chemical and stain resistance, hardness, and abrasion resistance. EBECRYL® 4900 finds application in radiation-curable coatings, particularly in areas such as automotive OEM coatings, industrial coatings, and metal coatings, showcasing its versatility and reliability in various end uses.

- Suggested Applications
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.; Thermoformable starting point formulation of a SB UV 2K system using EBECRYL® 4900 combined with multi-functional isocyanate EBECRYL® 4950.Component I.
