For model makers who like to build in foam, UHU POR expanded polystyrene glue is ideal for gluing hard foam like styrofoam. It is flexible, resistant to aging and waterproof. Transparent when dry, simply make sure the surfaces to be bonded are clean and dry. Setting time for the glue is 10~20 mins.
Please note that while some foams may appear to be styrofoam they may not be compatible with this glue. It is recommended that you try UHU POR glue on a test piece of foam first.
