Coatings that have been applied at thicknesses outside the manufacturer’s specification can lead to premature failure of the coating. A coating that is too thick or thin will often not have the same physical properties as a coating applied within the correct thickness range. Coatings applied too thin can … See more Poor surface preparation accounts for up to 75% of coating failures. This includes improper cleaning of the surface of contaminants, as … See more The conditions during coating application and curing are important for a successful application. A manufacturer’s coating specification will have the criteria that need to be met for a successful coating. This will include an … See more Some coatings are two part systems which require mixing of the two components on the job-site. Improper mixing of these components can lead to coating failures. Improper mixing of a … See more It is necessary for coatings placed in exterior environments to have resistance to UV light exposure. Molecules in the coating absorb the UV radiation from the sun and over time this radiation breaks the molecular bonds of … See more WebFailure Analysis of Polymer Coatings Polymer coatings typically contain elements whose presence and distribution can be characterised directly and quickly by SEM-EDS. The sample is traditionally prepared by freeze fracturing the …
WebFailures and defects can manifest themselves at various times in the life of a coating. To determine the cause and mechanism of coating failure, all possible contributory factors must be evaluated together with a detailed history from the time of application to the time the failure was first noted. WebSep 14, 2015 · A failure analysis was conducted to analyze the mode and causes of the disbondment of the three-layer polyethylene coatings from the surface of buried steel pipelines. The failure interface was analyzed through visual and microscopy investigations. Analysis of the coating at the disbonded interface revealed that the fusion bonded …
