From shoe uppers and bags to leather apparel and furniture leather, the finish gives leather rich color and gloss and also provides surface protection. Quality leather finishing should show a fine grain and texture, and it also needs to withstand everyday abrasion, moisture contact, and similar use, so that appearance and performance in use work together.
Guangzhou Jindong New Materials Co., Ltd. addresses the application needs of waterborne leather finishing, supplying aziridine crosslinking products and technical support for compatible carboxyl-containing polyurethane, acrylic, and similar systems. This helps improve the wet and dry rub resistance, water resistance, and solvent resistance of the coating, and strengthens the surface protection and durability of the finish.
In a compatible waterborne finishing system, the polyfunctional aziridine crosslinker can react with carboxyl groups in the resin, forming chemical links between polymer chains and a crosslinked network, improving the integrity and resistance of the coating film.
A suitable match of crosslinker and film-forming resin helps improve the surface protection of the finish, so that the leather keeps a good appearance and texture during everyday contact, abrasion, and use.
For the abrasion that leather goods meet in wear, carrying, and everyday contact, this helps improve the rub fastness of the finish, especially wet rub performance. Stronger film bonding reduces color transfer during rubbing and supports retention of leather color and surface appearance.
For use involving moisture contact and humid environments, suitable crosslinking helps improve the water resistance of the waterborne finish and the stability of the film under wet conditions, so that surface protection stays closer to everyday use requirements.
For solvents, cleaning media, and similar substances that may be contacted during finishing and use, the crosslinked network helps improve the resistance of the coating film. Combined with the article's use and the specific medium, this works with the customer to improve the protective performance and durability in use of the coating.
From clear protective layers that show grain to evenly colored pigmented coatings, different leather styles have different requirements for transparency, color, and gloss. Jindong pays attention to how the crosslinker works with the resin, pigments, and other finishing additives, and provides application support around film appearance and decorative effect.
Through product selection and formulation matching, customers are helped to balance coating protection, color appearance, and surface fineness, so that the finishing effect fits the design position of the leather article more closely.
In compatible formulations, Jindong aziridine crosslinking products can serve waterborne finishing systems for shoe-upper leather, bag leather, garment leather, and furniture leather, matching application needs such as base coats, topcoats, and surface treatment.
Around different leather substrates, coating structures, and end-product uses, we provide crosslinking product options close to actual application and help customers build leather finishing systems that consider both appearance and durability.
