Leather Cross Linker X
Leather Cross Linker X
Professional fast-acting hardener for waterborne polyurethane leather systems. Enhances film strength, rub fastness and chemical resistance in primers, colourants and top coats while maintaining flexibility.
What It Does
Leather Cross Linker X increases the degree of crosslinking in waterborne PU finishes, creating a denser polymer network and a tougher, more durable film. The result is improved wet and dry rub fastness, better resistance to water and household cleaners, and faster return-to-service.
Designed to be blended into the host component (primer / colourant / top coat) immediately before application. Mix only what you plan to use.
Professional Applications
- Automotive refinishing: bolster durability of seats and high-touch areas.
- Furniture finishing & restoration: improve wear and cleaning resistance.
- PU/artificial leather goods: enhance top-coat performance for bags, footwear and accessories.
Compatible Leather Types
Optimised for coated/pigmented leather and PU/artificial leather within waterborne PU systems.
Not recommended for suede or nubuck.
