Low-viscosity silicone elastomer
10 October 2011
NuSil Technology has recently unveiled its latest product; R-2188, a solvent-free, two-part, translucent silicone system. In fact, according to the company, R-2188 can be employed as a compliant, high-strength adhesive and encapsulant in power electronics applications specifically requiring a highly insulative material.
R-2188 is a non-corrosive material with a low modulus that overcomes stress between materials with different Coefficients of Thermal Expansion (CTE). Due to its high dielectric strength, it can withstand medium and high voltage; thermal and mechanical stress; and long, elevated operating temperatures. R-2188 has a variable cure schedule, low shrinkage, and is easily repairable.
It is effective in potting, encapsulating and coating modules, relays, power supplies, delay lines or complete electronic units, as well as a dip-coating for encapsulating components and printed circuit boards. As it is a low-viscosity elastomer with a long work time, R-2188 is also suitable for automatic dispensing.
