Nitoseal PU800 is a two-component gun grade elastomeric sealant for limited movement joints. After mixing, the resultant compound will cure to provide an exceptionally robust seal, while retaining a degree of flexibility. Nitoseal PU800 is abrasion resistant and withstands spillage of fuel oils, mineral acids and vegetable oils. Nitoseal PU800 can be used in joints between 5 mm and 50 mm wide.
