I am working on a project that requires very hydrophobic material. I have tried elastic, flexible, tough and black resin. Not much success with any of them. Does anyone know of any resin that has more hydrophobic properties? Or maybe a solution that could be put on them to react and make them hydrophobic? (I have tried mineral oil and Sigma-cote to try and coat the material to make it hydrophobic but with no success). Any help would be greatly appreciated!
