Silicones and Electronics
Long-term, reliable protection of sensitive circuits and components is becoming more important in many of today's delicate and demanding electronic applications. Silicones function as durable dielectric insulation, as barriers against environmental contaminants and as stress-relieving shock and vibration absorbers over a wide temperature and humidity range.
In addition to sustaining their physical and electrical properties over a broad range of operating conditions, silicones are resistant to ozone and ultraviolet degradation, have good chemical stability and are available in a variety of useful forms as conformal coatings, encapsulants and adhesives. Dow Corning's broad range of general purpose and specialty products offers you a choice of materials for your application needs.
Gels are very soft and cure in place to form a cushioning, self-healing, resilient gelled material. Cured gels retain much of the stress relief and self-healing qualities of a liquid while developing the dimensional stability of an elastomer.
Dow Corning offers a line of standard gels, a line of gels for applications requiring low temperature performance and a line of toughened gels for use where chemical adhesion and dimensional stability is required. Dow Corning also has a line of specialty gels including UV-curable and solvent/fuel resistant fluorosilicone gels.
