). Under these special conditions, control of applied film thickness must be observed to avoid cracking/fine cracking or solvent retention caused by excessive film thickness. Application at low temperatures generally requires addition of thinner to reduce paint viscosity to a suitable level, which however affects the sag resistance of the wet film and may induce solvent retention. Only when the substrate temperature rises above the specified minimum suitable temperature can the coating achieve the desired curing state and the full designed product performance.
