Internal stress, together with a lack of paint film flexibility and adhesion, are expected to be the main reasons for cracking and flaking of protective coatings. Mechanical properties and adhesion are to be discussed in later papers. Stress buildup at various climatic conditions has been studied. Two commercially available three-coat systems with polysiloxane topcoat were included in the test program. Both the individual coats and the full systems were investigated. The polysiloxane topcoats showed low levels of internal stress at all test conditions, and it is considered unlikely that topcoat cracking, and subsequent flaking, will occur as a result of the stress levels measured in this work.
