Lab Services

ResinLab’s laboratory is equipped to characterize polymers and formulations including potting compounds and adhesives. These capabilities support new product development, technical service, and quality assurance. The laboratory team is also available for contract lab services and custom formulation consulting work.


Using the Hitachi TM3030 Tabletop Scanning Electron Microscope (SEM) with Bruker Energy Dispersive X-Ray Spectroscopy (EDX) attachment, ResinLab is capable of imaging samples at magnifications from 15 to 30,000x, including a chemical analysis of the sample surface – helpful for a variety of applications:

  • Fiber impregnation
  • Fracture analysis
  • Polymer and composite analysis
  • Elemental analysis of impurities (to 0.1 atomic %)
  • Pigment and filler dispersion analysis
  • Image processing for sample feature dimensions (down to 500 nm)
  • Cross-sectional surface analysis of a cured material is possible for specimens with thickness less than 3 mm.

Test specimens must be solids.

Our Thermtest TPS 2500S “Hot Disk” Analyzer measures thermal properties with high accuracy and reproducibility. Our current capability allows for testing of solids, viscous liquids / pastes, and powders at room temperature. In a typical test configuration, two identical specimens are tested, prepared as disc-shaped ‘pucks’ of material, and compress the thin-film sensor that both sources and senses during the measurement.

Properties include:

  • Thermal diffusivity
  • Thermal conductivity
  • Specific heat capacity
  • Volumetric specific heat capacity



UL94 Testing



We also are equipped to perform UL94 testing, both vertical (UL94V) and horizontal (UL94HB) burn methods, with capability to cast bars at 3 and 6 mm. Please note that ResinLab is not a certified test laboratory, and UL certifications cannot be provided by ResinLab. These tests provide data that supports the pursuit of certification.

Keysight B2985A Resistivity Meter


Our Keysight B2985A Resistivity Meter with 16008B Resistivity Cell can measure volume and surface resistivity of electrically insulating materials. Temperature and humidity are measured in tandem with resistivity. The test meter is specified for use from 0 to 55 °C at less than 70 % RH. Values are typically generated at a source voltage of 500 V. A typical sample size is a 4” by 4” square with a thickness of 3 mm. The two faces of the square should be as flat and parallel as possible.

Resistivity measurement ranges are as follows:

  • Volume resistivity [1 x 107 to 4 x 1018 ohm-cm]
  • Surface resistivity [1 x 106 ohm/sq to 4 x 1017 ohm/sq]

The test cell can be used at temperatures ranging from 0 to 55 °C. The test meter can provide measurements in the frequency range 20 Hz to 300 kHz. To generate accurate and reproducible results, the fixture requires disc-shaped specimens with thickness less than 10 mm, with 2 mm or less ideal, a diameter of 40 to 56 mm (1.6 to 2.2 inches), and surfaces as flat and parallel as possible.

Our Phenix 4TCE100-10/D149 DC Dielectric Strength Tester measures the dielectric strength, or voltage required to generate failure, in insulating materials. We have Type 2 and Type 5 electrodes and a room-temperature oil bath with transformer oil that conforms to ASTM D3487 Type II. The unit can source voltages up to 100 kV with minimum ramp rate of 500 V/s. Samples must be thin and flat with parallel faces. When using the Type 2 electrodes, the specimen must be at least 2” in diameter. Each specimen must also be thin enough to fail within the maximum range of the unit, which usually corresponds to 2 mm or less thickness for the most highly insulating specimens.
