Training Courses

We offer tailor made training courses in all aspects of coatings technology. The following is an example of a Powder Coating Technology Training Course. Please contact us to discuss your own particular requirments.

This intensive two day course seeks to provide a clear understanding of all aspects of powder coating technology. The course includes an insight into the formulation and manufacture of coating powders, both thermoplastic and thermosetting. Particular emphasis is given to coating selection (based on the anticipated requirements of the end user), outdoor exposure, corrosion resistance and costs benefits associated with powder coating. Application techniques are discussed in-depth from simple fluidised bed dipping to fully automated electrostatic systems.

Health, safety and environmental isssues are covered for both the manufacturing and application processes.

The course includes a half-day practical session at a nearby powder coating installation, where there will be opportunities to apply coating powders, understand application parameters,and test coatings in production conditions.


Who Should Attend

This course will be particularly useful to those responsible for the introduction and use of coating powders and for those, who on a day-to-day basis, wish to apply them efficiently and effectively.

It is helpful if delegates have some knowledge of surface coatings and the principles associated with their application and use.
