Product Introduction
Those in the shoe manufacturing industry all know that whether a high-quality adhesive can perform well depends largely on choosing the right crosslinking agent - it directly affects how smoothly the construction goes, how strong the initial bonding is, and how long the finished product can last.
High-peel hardener R820 is a polyisocyanate hardener with precisely controlled reaction activity. One of the most practical features of this product is that it provides a long enough open time for operators to accurately align shoe components without rushing; at the same time, it won't slow down the assembly line rhythm due to being too slow, which is crucial in actual production and can save a lot of trouble.
In addition, high-peel hardener R820 has excellent initial adhesion. After application, it can quickly form adhesion to firmly fix shoe components, making operation much easier and greatly reducing construction difficulty. Besides, it has outstanding anti-yellowing performance. If you produce light-colored or white shoes and have high requirements for appearance, choosing R820 is definitely a safe bet - it can maintain the original appearance even after long-term use, without yellowing or discoloration.
Another key point is that it can easily pass the 24-hour hydrolysis resistance test. Even in humid environments, it won't cause adhesive delamination, fundamentally solving the hidden danger of unreliable bonding.
R820 also has strong compatibility and can be used with most shoe adhesives on the market. After adding it, the heat resistance and moisture resistance of the adhesive layer will be significantly improved, and it can also prevent the migration of plasticizers in the substrate, making the adhesive layer more tough and reliable.
Whether it's sports shoes, casual shoes or fashion shoes, high-peel hardener R820 is suitable for key processes such as outsole bonding and material lamination. For shoe manufacturers who want to balance construction convenience, bonding strength and long-term durability while controlling costs, R820 is really practical - it doesn't require extra spending, but can ensure product quality, making it a truly suitable hardener for the shoe industry.
