Non-Destructive Coating Analysis


In situ, non-destructive analysis of coatings

Whether you develop and manufacture coating systems or use coatings in your products or applications, Agilent offers a powerful new technology that can make your job easier.

The Agilent 4300 Handheld Fourier Transform Infrared (FTIR) spectrometer, quickly provides answers to some of the industry’s most pressing application challenges and regulatory issues.

The 4300 FTIR is portable – non-destructive analysis of coatings wherever and whenever needed, regardless of location, size, and physical shape of the substrate.

Measure chemical composition of coating systems

DevelopFormulation and composition

Coating performance as a function of formulation

Test mixture ratios of coating components and how they affect the performance of a coating, such as, resistance to heat, water, chemicals, or radiation.

Material identification

Ensure that the correct additives, fillers, resins, and cure agents are used in a coating system. Rapidly confirm, with a high degree of selectivity, that coating systems are formulated to the desired properties.

Degree of cure

Measure the progress of cross-linking in coating systems, and the degree of completion. Confirm cure agent/resin mix ratios. Determine the relationship of time, temperature, and presence of trapped solvents on curing processes (VOC guidelines). Minimize trapped solvent in special coatings such as those in contact with foods.

ApplySurface preparation and contaminant detection


Ensure that surfaces are clean and free of contaminants such as silicone oil or hydrocarbons, which reduce surface adhesion.

Surface activation

Ensure that surfaces are properly pretreated, as required to ensure correct coating adhesion – treating CFRP surfaces, for example, with plasma or corona to minimize release agents.

Surface preparation processes

Track the reduction in surface contaminants and optimize surface activation as a function of the process used. Develop better preparation and activation processes.

Film thickness

Determine that coatings are of the proper thickness and uniformity, as well as chemical content. Measure film thickness as a function of use to determine coating lifetime.

MaintainProduct performance as a function of use


Measure the effect of weathering, UV exposure, and general use-related changes. Test coating performance as a function of weatherometer-accelerated aging.

Environmental factors

Measure the effects of temperature, moisture, and all types of radiation on a coating.
