A Brief Introduction to the Effect of Adding Crosslinking Agents to Leather

Briefly describe the effect achieved by adding crosslinking agents to leather:

We all know that crosslinking agents are a type of coating additive that can have different effects when added to different products. They are widely used in water-based leather coating and can improve various physical properties of the coating when used in base and top coats. Applying it to leather can improve embossing formability. Used on leather top coating can improve dry and wet friction resistance and other physical properties. Used for all water-based acrylic acid, polyurethane, nitrocellulose and other systems to improve various physical properties.

This additive has both surface activity and hydrophobicity, and is a series of oil soluble non-ionic surfactants. In the production process of PU wet leather, it has the functions of good wetting, delaying solidification speed, and adjusting microporous structure. In addition, its hydrophobic genes also have a so-called release effect that prevents the fiber surface from tightly adhering to the PU layer, improving the leather feel.

This product belongs to environmentally friendly materials and does not contain any formaldehyde or VOC volatiles, making it an excellent environmentally friendly material in the world today. This product can also coexist with some compounds within a reasonable pH range for a long time, achieving a good shelf life for customer convenience.
