New Urethane Technology for Potting & Encapsulation in Electronics
. Epoxies are generally hard and tough materials. They provide excellent mechanical properties, good chemical resistance and good adhesion. However, they do not protect delicate components during thermal cycling and may provide stress during the exothermic cure. Silicones are excellent for high operating

How Filtroil Solves Oil Contamination Problems
Particulates enter the system in a variety of ways. The four main sources are: Impurities in new oil and contaminants inadvertently introduced when new oil is added to the system. Exterior pollutants and moisture in air entering via the breather caps. Particulates entering through seals, along

Finding just the right adhesive
and adhere to most substrates, including most plastics. Researchers have developed a wide variety of cyanoacrylate adhesives with varying viscosities, cure times, strengths, and temperature resistances. Typically, residual moisture on most surfaces is enough to trigger curing. They fix in about a minute

Thermoelectric Module Reliability
. Poor thermal contact will result in overheating of the TE module, which will significantly reduce performance and could lead to premature module failure. 3) Moisture. Moisture is the nemesis of thermoelectric modules. Moisture inside a thermoelectric module can lead to reduced performance

Epoxy Adhesives Hold Their Own
, and moisture. This sealing affect can also protect the joint from prolonged exposure to high vacuums or pressures, thermal cycling, and extreme temperatures. Designers can now take advantage of formulations that can withstand sustained structural service at 150 to 600 F. Factory bonding. Adhesive bonding
