Fellow Techs,

 

I have been asked to help select an alternate material that cures by
moisture / cross-linking (and not by solvent evaporation such as
HumiSeal type AR 1B31). 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..

 

Thanks again

-Joe
