... glass transition temperatures (Tg≥120°C) are developed. The objective of this study is to investigate blistering formation of high Tg FBE coatings in an attempt to understand the blistering mechanism. In this work, five (5) candidate FBE coating systems with Tg temperatures in a range of 125-155°C were...

... coatings the degree of delamination is easily determined by the intensity of blisters which generally arise already after short exposure periods. However, thick coatings with thicknesses above 2 mm take much longer for blistering and larger delaminations, and develop visible blisters only in an advanced...

... in weldments and HAZ. Of particular interest are those cracks due to SSC, HIC, and SOHIC. Compression-wave ultrasonics is primarily used for locating blisters, HIC, and corrosion in the shell plate. If vessels are entered, the preferred inspections technique is WFMPI and visual inspection of the vessel...
