Coating breakdown
WebAll feathering methods showed equivalent minor coating breakdown. The hand-tool-feathered areas showed the greatest amount of lifting. The areas repaired with the two-coat system showed no breakdown and very little lifting, while the one-coat UHS epoxy primer showed minor breakdown and more substantial lifting. This suggests that a two-coat ... WebThese coating breakdown factors are based on the international standard ISO 21809 serials.
