Active Cross-Linking

C​​rossing, an innovative startup based in Italy, is developing a new class of “Active Cross-Linking Agents” (ACLs) at competitive prices. ACLs can be applied in various fields due to their unique ability to bind different molecules using a “lock and key” mechanism similar to enzymes. The structures of ACLs are highly adaptable, allowing the creation of a diverse chemical library with varying properties such as activity, speed of action, performance, and industrial applications.

These compounds can be precisely tailored for specific manufacturing processes, enabling the production of non-toxic leather, active packaging, anti-fouling paints, antimicrobial building materials, and active cellulose, among others. ACLs function as a “glue” that bonds materials together but disappears without leaving any residue. This versatility opens up numerous industrial applications since the fundamental functional groups required are common to most natural and synthetic materials. For instance, ACLs can be used as tanning agents to cross-link collagen fibers in leather without leaving chemical traces. ACLs also enable the permanent attachment of antibacterial, anti-mold agents, and preservatives to polymers, enhancing the durability of products such as packaging, paints, coatings, and gelcoats, as the active components remain embedded throughout the product’s lifespan.
