Practical work

Time will be set aside through out the day to enable delegates to carry out supporting practical work.

Description

All coatings undergo phase changes during their life history. For a majority they are liquid during manufacture, storage and application. Following conversion to a dry film they acquire important, albeit slowly changing, solid-state properties which enable their protective and decorative functions.

The course will have a strong practical emphasis enabling delegates to:

Understand the principles and consequences of key coating attributes including:

1. 1.

   Wet film

2. 2.

   Viscosity and rheology

3. 3.

   Surface tension

4. 4.

   Dry film

5. 5.

   Mechanical properties

6. 6.

   Adhesion

7. 7.

   Permeability

8. 8.

   Opacity

9. 9.

   Gloss and sheen

Quantify test precision in terms of repeatability and reproducibility. Understand the concept of “Test Capability” in relation to control limits and specification.

Identify test methods and protocols from National, European and International sources.

Be aware of the correlation and limitations between test results and practical performance.

Carry out practical application and testing of paints using established test methods. Subject to prior notice every attempt will be made to meet delegates specific interests.

Note: The measurement and control of colour is not covered in this course.

Who should attend

This course is designed for all those working on the development, specification, and quality control of coatings where the use and interpretation of test methods is required.

The course is aimed towards all those requiring a thorough grounding in paint and surface coatings testing and will be particularly useful to technical personnel from raw material suppliers, paint manufacturers and end-users. No specific qualifications are required but a gain maximum benefit a basic knowledge of science would be useful.
