Thermoformable materials are currently used in the manufacturing of a wide variety of structural and functional plastic parts including automotive body parts, consumer electronic devices, and household appliances. The forming process for these materials requires a high degree of stretchability which generally corresponds to low crosslink density. The expectation is then for the coating to provide a high degree of performance such as scratch, chemical, and stain resistance that mimics a highly crosslinked system. Antecedently, one component (1K, no hardener, catalyst or activator) and multicomponent (2K, mix with hardener, catalyst, or activator) systems have been the chemistry of choice because of elongation possibility, but the tradeoff is in the final performance which comes up short. Allnex has developed a new technology, when used in the correct sequence, which allows the amalgamation of two chemistries, conventional and UV curable. Allnex will present a hybrid technology that allows the formation of an elastomeric coating that is tack-free with a high degree of formability but is transformed into a high-performance functional coating after exposure to UV light.
