Hi Joe, What is the environment that the conformal coating needs to protect the assembly from and is this an exercise to eliminate solvents altogether?

There are a range of mainly type UR materials to select that offer moisture cure and have differing Tg, CTE and Young's Modulus properties. I am very interested in any information that relates a conformal coating materials Tg, CTE and Young's Modulus to a coating's capability, board reliability etc..
