FAILURE ANALYSIS OF COATINGS

World Renowned Failure Analysis of Coatings Laboratory

ExcelPlas has performed hundreds of failure investigations of painted products as well as on numerous organic and inorganic coatings.  ExcelPlas’ paint failure analysis is supported by it’s scanning electron microscopy, metallography, chemistry, mechanical testing, accelerated life and paint laboratories.  As the world’s renowned coating inspection and failure analysis provider, we are the first choice for a broad range of clients across all industries, all over the world. We offer you state-of-the-art technology, techniques and equipment along with highly qualified technicians to bring you unrivalled expertise in the assessment of coatings. Plus, we work closely with coating manufacturers, providing quality control inspections to increase the quality of coating work.

A significant amount of financial loss is incurred every year as a result of premature failure of protective paints and coatings. The cost to repair such failures far outweighs the initial cost of painting due to the extreme cost and liability associated with excessive rigging and downtime to correct the problem.

The majority of paint and coating-related failures can be attributed to following SIX causes:

• Improper surface preparation – the substrate surface is not adequately prepared for the coating that is to be applied. This may include cleaning, chemical pretreatment or surface profile.

• Improper coating selection – either the paint or coating selected is not suitable for the intended service environment, or it is not compatible with the substrate surface.

•  Improper application – this can be a problem with either shop-applied or field applied coatings, and occurs when the required specifications or parameters for the application are not met.

•  Improper paint formulation,  drying, curing and over coating times –this problem relates to a lack of conformance to the required specifications or parameters.

•  Lack of protection against water and aqueous systems – this is a particularly serious problem with aqueous systems containing corrosive compounds such as chlorides.

•  Mechanical damage – which results from improper transport, handling of the painted or coated substrate, resulting in a breach in the paint or coating.

This newsletter is brought to you by ExcelPlas Coating Labs (http://www.excelplas.com/)

ExcelPlas Labs provides independent testing, analysis and investigation on protective coatings to prevent corrosion.

ExcelPlas has extensive analytical capabilities for testing of Protective Coatings and Insulation Consulting for major oil and gas companies.

We conduct corrosion surveys, coating sampling, coating analysis and testing to ensure coating specifications for a wide range of onshore and offshore clients in Australia and the Asia-Pacific Region.

ExcelPlas Labs offer a full range of coating testing and analytical services to Australia’s mining, oil, gas and infrastructure sectors.

Forensic analysis for undertaking various coating based failure investigations and problem solving.

ExcelPlas Undertakes Analysis & Testing of Polymer Coating Systems including:
• Epoxy Protective Coatings
• Epoxy-Phenolic Protective Coatings
• Fusion bonded epoxy (FBE) 
• Dual-Layer Fusion bonded epoxy (DLFBE)
• Liquid applied epoxy (LAE)
• Abrasion resistant overcoat (ARO)
• Three-layer PE (3LPE)
• Multi-component liquid spray  (MCL)
• Heat shrink sleeves (HSS)

Testing on Coatings that ExcelPlas can Undertake includes:
• Coating identification by Infra-red Analysis (FTIR)
• Degree of Cure by Thermal Analysis (DSC)
• Coating Filler Identification by X-ray Analysis (EDS/XRD)

• Coating Thermal Stability and Composition by Thermogravimetric Analysis (TGA)

DSC – Phase transition/volatiles / Tg / degree of cure/characterisation
TGA – Volatile compounds, inorganic mass % mix ratio
Element mapping for chlorides on paint flakes
Microscopy -Count layers and thickness of layers
-Assess porosity and voids
-Check distribution and orientation of filler particles
