Surface loss of colour and gloss in a coating from degradation of the binder by the UV components in sunlight. Can be seen as a white deposit on the cured coating surface.
The effects of coating constituent, coating layer thickness, permeability and temperature on transfer behavior of polystyrene thermal degradation product through coating layer have been studied.

When the oxygen fuel ratio is too low, slow particle flight speed and insufficient melt are the main reasons for the degradation of the coating compactness and mechanical properties.
