Leather Hardening Solution (Strong)

This is a strong hardening and shaping solution for leather areas requiring higher stiffness and support. Its water-soluble filling resin system features stable physical properties and nano-scale molecules with excellent penetration. When applied to the flesh side, it quickly penetrates and bonds with leather fibers, significantly increasing hardness while maintaining elasticity. Multiple applications can be applied after drying for enhanced results, achieving stiffness comparable to rigid cardboard. Testing on scrap leather is recommended before use. Slight color darkening after application is normal. Store in a cool, dark place away from direct sunlight.
