There is a difference between viscosity and thixotropy. For liquids viscosity corresponds to the informal notion of thickness.Certain gels or fluids that are thick (viscous) under static conditions will flow (become thin, less viscous) over time when shaken, agitated, or otherwise stressed. A thixotropic fluid is a fluid which takes a finite time to attain equilibrium viscosity when introduced to a step change in shear rate. Many times, high viscosity materials are also very thixotropic but it is possible to have thixotropic materials still be low in viscosity. It is also possible to have very high viscosity materials but have no thixotropic properties. EB-486 is a high viscosity, thermal adhesive. A very good and economical product, it is a very convenient and easy to use product. EB-486 is excellent for drawing heat away from electronic components. EB-486 is a room temperature cure adhesive and can be used in temperatures up to 120C. In LED applications, EB-486 is used as an environmental seal and thermal management on the LED. In aerospace applications, EB-486 is used as a sealant for gyroscopes in guidance systems.

High TemperatureEpoxyset has several potting and encapsulating compounds designed for high temperature resistance. Many of our products can withstand continuous temperatures of over 250C with very little electrical leakage, cracking, and mechanical breakdown. Used highly in the electronics and automotive industries, Epoxyset offers thermally conductive, flame retardant, and low expansion potting compounds for high temperature resistance.

EPOXIBOND EB-315 is a filled version of EB-115. Filling the system with non-conductive, 100% naturally ground powders significantly reduces CTE, ionic content, and cost of the system.EB-315 is used in aerospace electronic components for wire bonding and die attach. EB-315 is also used in producing MEMS probe cards and contact probes. EB-315 is a high temperature adhesive that can withstand temperatures of over 250C and can cure in 30 minutes at 150C. EB-315 has an extractable ion

A sometimes overlooked property of adhesive materials is the thermal resistance. What is thermal resistance?Thermal resistance is the temperature difference across a structure when a unit of heat energy flows through it in unit time.The thermal resistance of materials is of great interest to electronic engineers because most electrical components generate heat and need to be cooled. Electronic components malfunction or fail if they overheat, and some parts routinely need measures taken in the design stage to prevent this. EB-485 is 2-part, thermally conductive epoxy adhesive that can be combined multiple hardeners to offer different properties. The most standard hardener is EH-9 which offers a good general purpose epoxy adhesive with good chemical resistance and physical strength. With EH-21LP, the system becomes low viscosity, long pot life, and has good thermal shock and impact resistance. Also with EH-21LP, it has excellent low temperature properties and adhesion to glass. For high temperature properties and excellent chemical resistance, we recommend EH-6.
