Wound Protection / Medical care

Normally, there should not be any contact with water when bounding the wounds. It's a big problem especially when having a shower. The existing bandage can't proof the water very well. X is a new type of non-toxic and harmless colloid. Spray the liquid colloid on the bandage before going to the shower, the liquid colloid will soon turn into solid and form a thin film to proof water. And the thin film can be torn off from the bandage easily after the shower.
