Powder coating technology

Description

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 issues 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.

Description

The course provides an introduction to paint technology. It will explain why paints are used and the different functional types covering all aspects of decoration and protection. The major building blocks including polymers,pigments and additives will be described and the constraints that relate to different markets. Other aspects include manufacture and application. The question of what makes a good paint will be discussed in terms of performance and test methods, against the background of legislation and the pressure for sustainability and a low carbon footprint. A commercial overview indicating the major market sectors both decorative and industrial is also included.

Who should attend
