Removing Epoxy from Polyester Uniform?

Does anyone have any ideas of how to remove white epoxy glue from navy blue polyester uniform pants? My husband wears a uniform to work and had to load a piece of equipment on his truck, saw the white stuff, and didn't realize it was epoxy glue he would be sitting down in. Now, he has 1 less pair of pants to wear to work and I am hoping someone has a solution to deal w/this. Please and thank-you.
