HumiSeal® is pleased to announce the release of a new two-part silicone conformal coating and potting material. 2C51 is a versatile, fast curing, and high dielectric strength material that can be tailored to the users’ application methodology.
The 2C51 provides superior protection as a conformal coating or if used to fully encapsulate the PCB. A simple 1 to 1 mix ratio assures accurate blending of the two parts, while its two color part packaging allows for easy verification of complete mixture. The 2C51 autocatalytic cure enables curing without applied heat, although it can be accelerated with a mild temperature increase. Full cure can be achieved in 30 minutes at 70oC or 60 minutes at room temperature.
The cured 2C51 is a transparent film with slight blue tint visible at higher thickness levels. Strong dielectric properties will provide unmatched circuit protection. This new 100% solid material with zero grams per liter VOCs enables an environmentally friendly application.
