Resinlab offers:Resinlab

  • Toll blending your in-house formulations
  • Product modification of color, viscosity, cure speed, hardness, and any other property you may need
  • State of the art laboratory instrumentation that allows us to validate design parameters
  • TA Instruments 2910 Differential Scanning Calorimeter that characterizes the thermal response of products. Exotherm, glass transition points, and melting points are among the key properties.
  • Thermocouple Data Acquisition captures the reaction profile and exotherm of a curing polymer. This can be run at various ambient temperatures to show the effect of mass, geometry, and surrounding materials on heat generation and dissipation to assure low stress casting.
  • MTS QTest 25 is a versatile physical tester used to measure a product’s tensile strength, elongation, compressive and flexural properties and adhesion to various materials.
  • Nicolet Nexus 470 FT-IR is used to identify the chemical fingerprint of polymers.
  • Use of Brookfield Viscometers: DV II + Thermosel Viscometer, DV III Ultra Thermosel Viscometer, RVT
