Paints and vanishes for use on exteriors of buildings must be protected from the effects of solar radiation which accelerate their degradation (photolyiss and photochemical reactions). Given that: M=500 g/mol; Emax=15,000 L/mol/cm for lambdamax=350nm. What must be the concentration (expresses in g/L) of a UV additive M such that 90% of the radiation is absorbed by a coating of thickness 0.3mm? thank u so much.
