green glue and exterior sheathing

Hello, I am planning on using green glue and and 2 layers of gyp board inside after reading that this would act similarly to 4 layers of drywall without green glue. I thought that I would use green glue between the exterior osb, but I can't seem to find the information on if it is ok to use for the exterior. Can you use green glue between exterior osb sheets? Thanks Aaron
