NINGBO INNO PHARMCHEM CO.,LTD. is proud to introduce a cutting-edge liquid crosslinking agent designed specifically for the textile auxiliary chemicals market. This advanced product, a transparent viscous liquid, represents a significant step forward in textile finishing technology, offering enhanced durability and performance characteristics for a wide range of fabrics.

At its core, this product is an anionic hydrophilic modified polyisocyanate. Its unique chemical structure provides excellent water dispersion properties, making it easy to incorporate into water-based textile finishing formulations. A key advantage is its composition: it is environmentally friendly and solvent-free, boasting a 100% solid content. This not only supports greener manufacturing processes but also offers efficiency in transportation and storage.

The primary application of this high-performance liquid crosslinking agent is in two-component polyurethane coating systems, typically used in conjunction with water-based hydroxyl resins. Upon curing, the resulting film exhibits exceptional qualities, including high gloss, high fullness, and resistance to yellowing. More crucially for textiles, it imparts excellent chemical resistance, superior water resistance, and outstanding friction resistance. This makes it ideally suited for treating special fabrics such as T/C blends, 100% polyester, nylon, denim, and various waterproof fabrics. The product is capable of self-crosslinking at room temperature, functioning effectively as a bridging agent or extra strong color fixing agent, particularly beneficial for applications like denim and nylon auxiliaries.

A major benefit highlighted by NINGBO INNO PHARMCHEM CO.,LTD. is the minimal impact this crosslinking agent has on the inherent properties of the treated fabric or print paste. Unlike some traditional agents, it does not negatively affect the tensile strength or hand feel of elastic glue pastes, even at recommended dosages. Furthermore, it ensures that printed areas do not yellow, change thickness, or lose their desirable tactile quality. Its ability to significantly improve the washing fastness, as well as dry and wet friction fastness, without compromising the fabric's hand feel, is a critical advantage in producing high-quality, durable textiles. The product is also noted for being VOC free, contributing to a cleaner working environment and less environmental impact.

Technical specifications indicate its nature as a transparent viscous liquid with a polyisocyanate property. It maintains a solid content of 100% and exhibits a viscosity typically ranging from 2000 to 3000 CPS at 25ºC, with an NCO content around 21.3%.
Proper handling and storage are essential to maintain product integrity. It is packaged in various sizes, including aluminum cans and iron drums (1kg, 20kg, 220kg), offering flexibility for different scales of use. Storage is recommended at 5-30ºC, with a shelf life of approximately one year when kept sealed. It is crucial to pay attention to sealing after opening, as exposure to high temperature or prolonged contact with air can cause it to solidify into a glass-like state. For application, it can typically be used after dissolution with a suitable ether solvent, provided the solvent does not contain hydroxyl groups and requires urethano treatment.
