Outsized Impact: Graphene Nanoplatelets for Protective Coatings

Jotun Launch SeaQuantum™ Pro U Coating
A one component hydrolysing silyl acrylate antifouling coating. It provides excellent fouling protection, ultra-low friction and incomparable hull performance. This is achieved through highly predictable and stable self polishing characteristics reducing hull deterioration, friction and speed loss.

Carboline Issue New Specs for Thermaline™ 4900 Coating
Silicone acrylic coating  suitable for high temperature exposures up to 260°C.  Heat cure above 149°C is recommended and will impart added strength and integrity to the coating.

ISO Accredited 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.
