Slimes fibro-seal technology seeks out punctures as they occur to repair flats before you even know they happened. As the Slime-treated tire rotates, centrifugal force pushes the sealant to the tread area to create a layer of protection, repairing punctures as they occur or treating existing punctures. Slime utilizes a state-of-the-art blend of environmentally friendly fibers, binders, polymers and proprietary congealing agents which intertwine and clot within the puncture. This Fibro-Seal lattice, together with the viscous delivery system (the green goo) seeks out and tightly packs itself into the puncture, preventing and repairing flats with a flexible, long-lasting plug. Slime Sealant can be pre-installed into any tubeless tire, but is recommended as a repair-only in passenger vehicle tires. Repairs punctures up to 1/4 inch (6 mm) using Fibro-Seal technologyRemains liquid inside the tire, coating the tread area as the tire rotates for up to 2 yearsSlimes green promise nontoxic, non hazardous, non flammable, non aerosol and water-solubleContains rust and corrosion inhibitors to help maintain the integrity of the rimTPMS safePreinstall for flat tire prevention in ATVs, trailers, lawn tractors, wheelbarrowsGolf carts and many other non-highway applications
