Our water-based Repel formula is VOC-free and does not contain PFAS, PFOA or PFCs (forever chemicals). It safely creates a durable, breathable barrier that dries clear and effectively protects against liquid and dirt. Repel is safe to use on most absorbent materials including leather, suede, nubuck, canvas, cotton, nylon, knit, woven, mesh and more (Not recommended for unsealed leather or vegetable tanned leather). The non-aerosol delivery system outputs a continuous fine mist covering large areas quickly and evenly in all directions. This product’s efficacy has proudly achieved a score of 100 (ISO 5) using the AATCC Test Method 22-2005. You can learn more about the AATCC Test Method here. The bottle is fully recyclable. We encourage you to save the spray applicator and purchase the available Repel Refill when it comes time to re-up. Additionally, we proudly use Avery Dennison CleanFlake™ technology which ensures that labels and adhesive separate from PET every time, increasing the yields of pure PET flakes.
