Facilities
Adherent Laboratories has a fully equipped adhesives and
materials laboratory located in St. Paul, Minnesota. Partnering
strategically with other research, educational and testing
laboratories Adherent Lab's capabilities rival that of any major
adhesive company.
Facilities and capabilities include:
Analytical

- AA, TGA, TMA, NMR, DMA, FTIR, DSC, GPC
- Electron microscopy
- Flavor, odor and sensory analysis
Physical and Material Testing
- Instron tensile and compression testing
- Rheology (oscillatory, capillary, Brookfield)
- Gardner and Hunter Colors
General Adhesives Testing
- Viscosity
- Heat resistance (SAFT, PAFT, IOPP)
