Spring series of FSCT Virtual Learning Conferences features two-part course on cure characterization.The FSCT FSCT Federation of Societies for Coating Technology FSCT Fire Support Control Terminal continues its Spring series of Virtual Learning Conferences with a two-part course on cure characterization. On April 12, Dr. Theodore Provder, of North Dakota State University North Dakota State University, at Fargo; land-grant and state supported; coeducational; chartered and opened 1890 as North Dakota Agricultural College, achieved university status in 1960. , will present "Cure Characterization Applied to Product R & D and Problem Solving: Part I." Dr. Provder will present Part II of this course on April 26. These courses can be taken individually or as a series. Course Description A rationale for characterizing the cure process with a variety of cure responses are presented from the perspective of relating end-use properties to measured fundamental properties obtained from cure characterization methods. The methods include differential scanning calorimetry Differential scanning calorimetry or DSC is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference are measured as a function of temperature. (DSC), dynamic mechanical analysis (DMA), Fourier transform infrared spectroscopy (FTIR FTIR Fourier Transform Infrared (spectroscopy) FTIR Frustrated Total Internal Reflection FTIR Fourier Transfer Ir ) [thin film and evolved gas analysis Evolved gas analysis (EGA) is a method used to study the gas evolved from a heated sample that undergoes decomposition or desorption. It is possible to detect which gas is evolved using evolved gas detection (EGD). ], chemorheology (CR), and dielectric spectroscopy (DS). The basic principles of these methods are presented and applied to the determination of the degree of chemical conversion (DOC) ([e.g., DSC, FTIR] and the degree of chemical cure (DOC) [e.g., DMA, CR, DS] for a wide variety of coatings systems (powder, electrocoat, gel coat, high solids, etc.) and chemistries (epoxy, epoxy-polyester, acrylic-isocyanate, styrene-unsaturated polyester, etc.). Also shown is how isothermal i·so·ther·mal adj. Of, relating to, or indicating equal or constant temperatures. isothermal, isothermic having the same temperature. FTIR chemical conversion data can be used to obtain fundamental kinetic rate constants for deblocking and cure reactions for isocyanate-curable systems. The course shows that glass transition temperature The glass transition temperature is the temperature below which the physical properties of amorphous materials vary in a manner similar to those of a solid phase (glassy state), and above which amorphous materials behave like liquids (rubbery state). is a very useful parameter for monitoring cure and constructing time-temperature-transformation diagrams. The utility of the time-temperature superposition principle for constructing master curves from DMA DOC data is shown to enable the prediction of cure behavior for a range of time-temperature profiles. Dr. Provder demonstrates that the DMA storage modulus in the rubbery region can provide estimates of the crosslink density that compare well with that obtained from swelling experiments. In addition, the course illustrates how combining information from several cure characterization methods provides a very comprehensive characterization of the cure process. Cure Characterization Applied to Product R & D and Problem Solving: Part I Thursday, April 12 2:00-3:30 (ET) Part I is intended for R & D personnel, coating chemists, product development managers, and others with an interest in cure characterization. This course focuses on such topics as: * Relationship of end-use properties to measured fundamental parameters * Principles of DSC, instrumentation, and application to determining kinetics of chemical cure and DOC * Application of DSC to powder coatings cure, gel coat cure, acrylic-isocyanate cure, and to problem solving * Principles of DMA, instrumentation, and application to determine chemorheological kinetics and chemorheological DOC in reacting thermoset A polymer-based liquid or powder that becomes solid when heated, placed under pressure, treated with a chemical or via radiation. The curing process creates a chemical bond that, unlike a thermoplastic, prevents the material from being remelted.
