Surfacecoatings requireabsolute clean and dry workpiecesdevoid of remainders like fat, oil or salts. Only smallamounts of these surface impurities will result in a pooradherence of thecoatingsubstance with all the negativeimpacts on the product quality.

FT-IR spectroscopy and microscopy can analyze large surface area as well as microscopic contaminations on metallic / reflective surfaces. Typical residues include:

• Oil or other lubricants
• Tensides and residual cleaning agents
• 粒子和类似的公司ntaminants
• inclusions in faulty coatings.
  

In addition to using the correct coating material, it is primarily important to determine the uniform presence of the coating layer and its homogeneity. Incorrect application of the coatings leads to product failure and defects.

FT-IR spectroscopy is a very powerful technique to obtain information about the presence and chemical identity of coatings. However, for particularly small substrates (e.g. a metallic wire), infrared microscopes are necessary for analysis. FT-IR microscopy can help to verifiy a coating's:

• Presence
• Thickness
• Uniformity
