What does DCA stand for?

16) In addition to static measurements, the system also runs a dynamic contact angle protocol for the measurement of water contact angle hysteresis.

The performance of INT-PRW24 was verified by two test methods, including dynamic contact angle, a timed, visual measurement of the test paper's absorption of a picoliter droplet; and ultrasound, a timed measurement of signal transmission through the test paper.

The dynamic contact angle just before the appearance of coating defects is about 180[degrees], implying that coating defects will be the air entrainment type.

Surface Properties The surface properties of the semi-IPNs were investigated using Cahn 322 Dynamic Contact Angle Analyser and WinDCA software.

For surface chemistry, dynamic contact angle, surface tension and critical micelle concentration systems are highlighted.

A very good correlation of the application properties of these coating materials and their surface properties, such as high dynamic contact angle (DCA), low surface-free energy (SFE) and surface morphology, was observed and is discussed.

Figure 3 shows the results of dynamic contact angle measurements for all four SiPP samples.

Also featured are dynamic mechanical rheometers, capillary rheometers and melt flow index and melt flow rheometers, a differential scanning calorimeter, thermogravimetric analyzers, high mass, high temperature and high pressure TGA, thermomechanical analyzers, dynamic mechanical analyzers, the pvT100 unit for the measurement and analysis of the thermodynamic properties of a range of polymers, the Thermoflixer for measuring the thermal conductivity of plastics and other materials in solid, liquid and melt-phase as a function of temperature, and dynamic contact angle instrumentation.
