Compositional Analysis of Coatings

Coating materials are formulated to possess certain compositional properties that are important for application, curing, and performance. These properties are often tested to establish baseline values, in the event that field sampling and analysis of the coatings is invoked by the specification. In this manner, a facility owner can be assured that the product shipped to the project site is the same in composition to that which was originally tested and qualified for use. KTA’s staff of chemists performs compositional properties analysis (individual components and/or mixed components) according to standard ASTM procedures, including:


Fourier Transform Infrared Spectroscopy
Volatile Organic Compound (VOC) Content
EPA Exempt Solvent Analysis
Water, percent by mass
Total Heavy Metals (Lead, Cadmium, Chromium)
Leachable Heavy Metals (8 RCRA metals) via TCLP
Epoxide and Amine Values
Isocyanate Group Content
Hindered amine light stabilizer (HALS) – qualitative analysis

Total solids, percent by mass

Pigment, percent by mass

Metallic zinc content, percent by mass in primer
Total solids, percent by volume
Mass per volume in grams/liter
Viscosity – Stormer and Brookfield
Pot life via Stormer viscosity
Sag resistance
Dry Time
