UV clearcoats

Automotive paint weathering research is based on measurement of chemical changes by means of FTIR (all coating layers), transmittance UV (clearcoat only) and ESR (determination of active HALS content of clearcoat and basecoat slices from weathered test panels) [826]. Gerlock et al. [827,... 

UV clearcoats are a common protective silk screen coating that can provide both a flexible and glossy surface property to point-of-sale promotional products such as polyvinyl chloride banners, as well as to fabrics. The coating is commonly comprised of about 40 to 80% by weight of an aliphatic urethane diacrylate oligomer and approximately 20 to 60 % by weight of a mono-functional component. 

Hybrid solutions that utilize both fixed lamps in combination with automated lamps. An example of this type of solution is the current concept to cure UV clearcoat on car bodies. The fixed lamps cure the vertical surfaces of the vehicle, while the horizontal lamps are mounted in a roof-beam that follows the profile of the...
