The preparation of coating formulations involves the dispensing and mixing of a variety of polymers, crosslinkers, catalysts, and other additives. Many resins and crosslinkers are relatively high viscosity materials and can be difficult to handle. Dispensing of these resins is accomplished through the use of disposable pipette tips and mixing by magnetic stirring. By using a disposable tip for each dispense, the chance for cross contamination is reduced and the need to thoroughly wash the pipette between each use is eliminated.
An automated system for measuring color and gloss has been developed at NDSU. This system is compatible with all of the flat substrates generated by the CMRL. The on-board computer up-loads the data to a central database for easy access through a web based browser. Color measurements are made with an X-rite integrating sphere spectrophotometer while gloss measurements are made with a BYK-Gardner gloss meter reading at 3 different angles.
Aramis Confocal Raman Imaging System Horiba Jobin Yvon’s Raman Spectrometer is a confocal system capable of x,y mapping and depth profiling. The advanced optical technology and software on the LabRAM ARAMIS provides access to faster and more detailed chemical images. While not every sample is an efficient Raman scatterer, the ARAMIS ensures that samples such as pharmaceuticals, minerals, polymers and semiconductors can routinely be mapped using fast point acquisitions.
Cyclic corrosion tests automatically expose test specimens to a series of different environments in repetitive cycles. Cycles like Prohesion® may consist of fast cycling, rapid temperature changes, a low humidity dry-off cycle, and a different corrosive solution. Continuous salt spray exposure cycles are widely specified for testing components and coatings for corrosion resistance. With the Q-Fog CCT one can cycle through all of the most significant corrosion environments in one chamber.
• D8 Discover with GADDS Multipurpose X-Ray Diffractometer • Bruker AXS’ D8 Discover with GADDS is a multipurpose X-Ray Diffractometer capable of performing a variety of analytical techniques with minimal reconfiguration. X-Ray Diffraction (XRD) is an extremely powerful technique utilizing non-destructive analysis to study a wide range of materials. Research Ops in-house D8 Discover plays a significant role in the analysis and characterization of sputtered thinfilms and synthesized crystalline and semicrystalline materials. XRD is best known for phase identification of crystalline solids.
Dimension Elite 3D Printers use ABSplus™ modeling material, a production-grade thermoplastic that is durable enough to perform virtually the same as production parts. Models printed with Dimension 3D Printers have customer-proven toughness – from commercial sprayers tested at pressures up to 60 psi, to final parts on M1 tanks normally machined in aircraft-grade aluminum.
A SpeedmixerTM from Flacktek is used to mix difficult components such as extreme viscosity or paste-like materials. This device uses disposable mixing vessels of several sizes to mix in a non-contact fashion. Glass beads can also be added to provide a milling action to efficiently disperse powders into liquids.
Buehler’s EcoMet 3000 is a variable speed grinder-polisher with an 8 (203mm) low profile aluminum platen and a Buehler universal mount. Platen speed is variable from 10 to 500 rpm. Percent Load display shows the amount of load on the motor. A built-in center mount facilitates use of the AutoMet Power Head with either wheel. The instrument is designed for sample preparation applications which require two grinding-polishing stations.
•Surface finishes can be achieved down to a mirror finish depending upon material and technique.
