Course Content

CHARACTERISTICS & PROPERTIES OF PAINTINGS & COATINGS

1.5 days

  • Paint components. Binders and plastifiers, pigments, fillers, colorants, additives, solvents.
  • Physical characteristics of paint. Fluidity at different temperatures, % solids, lifetime, hardening, drying, safety problems; atmospheric conditions consequences. Paint manufacture and recent developments.
  • Different types of industrial paint:
  • Physically drying paints, oxidative paints, chemical polymerization paints, anticorrosion systems for aggressive environments.
  • Advantages and drawbacks of the different types of paints.
  • Paints for special environments (abrasive, high temperature, low temperature) and for different materials (stainless steel, galvanized steel, aluminum, concrete, etc.).
  • Composition of a paint system (role of coats and compatibility).

PAINT APPLICATION IN INDUSTRY

1.5 days

  • Preparation of surfaces:
  • Rust scales, roughness, surface profile, degree of care, preparation by organic solvents, preparation by high pressure water jetting, wire brushing, blast cleaning, sponge jet.
  • Tests on samples, chemical conversion of surfaces (passivation, phosphating, chromating, oxalating, etc.).
  • Applications:
  • Main paintings parameters: use of brush, rollers, spraying, composition, surface tension, viscosity, temperature, solvent volatility, speed of jet leaving gun, type of jet and regulation, spray gun and equipment handling.
  • Compressed air.
  • Airless high pressure spraying (principle, installation, regulation, tests, etc.).
  • Thermal spray aluminum.

INSPECTION, CONTROL & COMMISSIONING

1.5 days

  • Paint defects, causes, control procedures. Control of raw materials and finished products, application control, coating control:
  • Causes of deterioration (chemical, mechanical, photochemical, biological, etc.). Prevention and repair techniques.
  • Specifications and rules. European standards, ISO, etc. and safety regulations: qualification of painting systems:
  • Qualifications of painters. Inspection and control: tests performed on painted equipment and structures.

FIELD INSPECTION, CONTROL & COMMISSIONING

0.5 day

  • Perform and assess field painting work.
  • Review the specification given to the contractor.
  • Assess the QA/QC documents that are available during the field inspection and check for consistency with your company specification.
  • Check for painters qualifications, and observe when they perform the work. Debriefing & good practices.
Ways & Means
  • Learning process including case studies.
  • Visit of a paint workshop or a control laboratory.
