Melcor Thermoelectric Cooler Sealing

Sealed Thermoelectric Coolers When used in conjunction with recommended assembly sealing techniques, these moisture protection options help prevent water or gases from contacting the TE elements and conductors.
		Epoxy Sealing (EP) - A low-density (lightweight), syntactic foam epoxy resin for electronic encapsulation and perimeter sealing. When cured the material is completely uni-cellular and therefore the moisture absorption is negligible. The material exhibits a low dielectric constant, low coefficient of thermal expansion and low cure shrinkage. It contains microballoons to reduce thermal conductance. Usable temperature range is -40 to +130°C.
		Silicone (RTV) - A perimeter seal that retains elastomeric properties over a wide temperature range. The non-corrosive material exhibits excellent electrical properties and UV, chemical and weather resistance. Usable temperature range is -60 to +204°C.
		Conformal Coating (EC) - Conformal coating is a transparent, general purpose dip epoxide surface coating that is used for coating electronic components for corrosion protection and high insulation resistance. Not a perimeter seal. Can be used in conjunction with RTV. Usable temperature range is -55 to +150°C.
