Various products require paint films that possess properties specific to that
particular product. For example, automobiles and trucks require finishes that
resist road salt, gasoline, oil, harsh chemicals, detergents, bird droppings, tree saps
and acidic components in rain and air. Home appliances such as washing machines
must have finishes that stand up to water, bleach and alkaline detergents.
Machinery finishes must resist cleaning agents, heat-transfer fluids, cutting oils
and various lubricants.
