Is the paint already cured? How many and which solvents are still contained in
the paint? Which emissions occur in the applied temperature range? Why can the
paint be applied better by the competitor? Why does the painted part break?

Thermal Analysis
for Paints

Such questions as these must frequently be answered for the development of
paints. Conventional tests are often only single-point measurements and therefore
not sufficient. In order to better understand the most complex influences more
comprehensive analyses are in great demand.
The proven thermoanalytical methods in polymer technology in accordance with
DIN 51005 or ASTM E 472 are an excellent tool. The NETZSCH applications volume
“Focus on: Thermal Analysis for Paints” was released in cooperation with the
Department of Plastics and Rubber Engineering of the Würzburg-Schweinfurt
University of Applied Sciences and features a wide range of applications with
practical examples from industry. With the help of DMA (Dynamic Mechanical
Analysis), investigations of clear and soft coats as well as paint structures are
presented. Solvents and decomposition products of hydro clear coatings and soft
coatings are identified using TG-FTIR (Thermogravimetry with Fourier Transform
Infrared Spectroscopy). Description of the curing behavior of powder paints by
means of DSC (Differential Scanning Calorimetry) is emphasized. These results are
analyzed kinetically and simulated along with rheometer measurements, with
respect to practice-relevant temperature profiles. Paint developers and users will
find not only assistance but also additional suggestions for their application areas.
