| New White Paper: Evaluating Electrically Insulating Epoxies |
Learn how fundamental electrical properties of epoxies, such as dielectric constant, dissipation factor, dielectric strength, surface and volume resistivity, are measured and what values are desirable. The specific composition of resin and curing agents as well as changes in temperature, fillers and other variables will also affect the electrical properties of a cured epoxy system. Three major types of curing agents are explained along with their benefits and trade-offs with respect to electrical properties.

| Low Viscosity Conformal Coating Cures Quickly |
Master Bond MasterSil 773 is an ultra low viscosity, solvent-free, one component silicone based conformal coating. This system has a viscosity of 60-70 cps at 75°F. It is designed to provide protection to electronic circuitry in high humidity environments and resistance to shock and vibration. This highly flexible, low hardness system is very easy to repair and has a fast tack-free time. A most useful feature of MasterSil 773 is that it maintains its low modulus over the wide temperature range of -80°F to in excess of +300°F.
