| Résumé : |
Characterization of dry and cure is very important in the development of paints, coatings, and adhesives. 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. |
