The values I have are 6.3 Er for E-glass and 3.6 Er for 
     (Multifunctional) resin.
     
     (Can't answer the S-glass question but I'd like to see the answer.)
     (S-glass is >$$$$$ and available with high temp resin systems. i.e.,
     CE and Poly. It has more favorable CTE values like 9 PPM in X and Y.)

Can anyone add to this the Dk for E-glass vs S-Glass?
