PAINT, PIGMENT, AND PROTECTIVE COATING ANALYSIS

Our laboratory uses Fourier Transform Infrared Spectroscopy (FTIR) for the analysis and identification of the type of paint applied to any surface. This highly sensitive technique allows the analysis of the chemical compounds in coatings, even on very small surfaces, using the FTIR microscope. This instrument enables precise analyses without damaging the sample, identifying the materials used in the coatings and providing detailed information about their chemical composition.

Measuring paint thickness is essential to ensure proper substrate protection and verify that the coating meets required standards. APM performs precise thickness measurements using advanced techniques in compliance with UNI EN ISO 2808 standards. A coating that is too thin may not provide the necessary protection, while one that is too thick could cause defects or compromise its functionality.

Corrosion resistance is one of the critical aspects of protective coatings, particularly in industrial and marine environments. We perform salt spray corrosion tests according to ASTM D714, which simulates aggressive environmental conditions to test the paint's ability to resist corrosion. This test helps assess the durability of the coating and its protection against the corrosive action of salts and moisture.

Adhesion testing is essential to check if the paint properly adheres to the substrate without peeling or flaking. We use the cross-hatch method, which involves cutting the paint into a series of squares to assess the adhesion strength of the coating. This test is crucial to ensure the quality of the painting process and avoid application defects that could compromise the coating's performance.

Hexavalent chromium is a hazardous substance for both health and the environment, found in some metallic coatings. APM offers hexavalent chromium analysis services to identify and quantify this substance in protective coatings. The presence of hexavalent chromium must be monitored to comply with environmental and health safety regulations.

Phosphating is a surface treatment that enhances paint adhesion and corrosion protection. Our laboratory performs precise thickness measurements, along with chemical and morphological characterization of the phosphating layer. These analyses allow verification of the treatment’s effectiveness and ensure that the coating meets the required resistance characteristics.

Blistering (formation of bubbles on the paint surface) is one of the most common painting defects, often caused by contamination, moisture, or poor surface preparation. Our laboratory performs in-depth analyses to identify and understand painting defects, including blistering, cracking, yellowing, and other imperfections that could compromise the aesthetics and protection of the coating.
