Miscellaneous Coatings Testing
KTA’s laboratories conduct a multitude of routine analyses including appearance tests (color difference, gloss retention, hiding and contrast ratio); wet tests (density, solids content by weight and volume; pigment content, fineness of grind, flash point and package stability) physical properties (chemical spot testing, hardness, resistance to chipping and scrub resistance) and free film testing including tensile/elongation/flexural, and water vapor transmittance.
Analytical tests include Fourier transform infrared spectroscopy for fingerprint analysis of coatings; atomic absorption spectroscopy for toxic metal and pigment analysis; gas chromatography-mass spectroscopy for solvent and blister liquid analysis; high performance liquid chromatography for analysis of resins and additives; ion chromatography for analysis of blister liquids, differential scanning calorimetry for zinc content and glass transition temperature analysis; digital microscopy (for cross-sectional and surface examination), Scanning Electron Microscopy for surface examination and analysis, and Electrochemical Impedance Spectroscopy for performance evaluations of protective coatings.
KTA’s physical laboratory conducts all of the testing listed under Paint (Coatings) Performance Testing, and also offers slip resistance testing of walking/working surfaces; dry fall coating evaluation using a specially designed 18 foot vertical drop enclosure; and independent evaluations of surface preparation equipment performance.
KTA has demonstrated such services on the following representative projects:
