It can be challenging to assess dry and cure of these products on a quantitative, non-biased basis. Although there are many different techniques utilized to assess drying, curing, and performance, some are often qualitative at best. It would be useful to have quantitative techniques available to access these properties. In this paper, we introduce a novel automated dynamic dry time recorder (ADDTR) device that measures dry and cure of coatings similar to mechanical dry time recorders that meet ASTM Method D 5895. The novel device is capable of recording and graphically displaying the coating drying profile as it dries so that drying time events may be easily identified, archived, and analyzed, even for clear coatings. Such analysis allows easy and quantitative comparison between different coating systems, chemistries, driers, etc. In certain configurations, the tester may also be utilized as a hardness, toughness, and adhesion tester.

Evaporative Dynamic Oscillation (EDOT): a versatile technique for in situ characterization of polymers and coatings / Ronald T. Obie in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 15, N° 2 (03/2018)

Langues : Américain (ame) Catégories : Caractérisation Oscillation dynamique Polymères Revêtement -- Séchage Revêtements organiques Rhéologie Viscoélasticité Index. décimale : 667.9 Revêtements et enduits Résumé : Characterization of material properties of polymers, films, and coatings is an important component to understand and subsequently to predict performance of these materials. It is often challenging to determine material properties of thin films. Additionally, determination of material properties of polymers can be challenging if these materials do not consolidate to a solid, particularly when residual solvent is present in the sample. In this paper, we introduce Evaporative Dynamic Oscillation (EDOT), a technique that allows the characterization of rheological properties of polymers and coatings in thin film form, in situ. Results indicate that EDOT can successfully characterize drying and cure of coatings and polymeric films by monitoring viscoelastic properties of these films as a function of time and temperature.
