PU Hardeners

Hardeners, also known as curing agents or cross-linking agents, are substances added to adhesives to accelerate hardening and curing. PU hardeners transform a basic adhesive into a high-performance bond, ensuring shoes are built to last.

Why they're essential in shoe glue adhesives?

• Creates stronger, more durable bond: They trigger a chemical reaction that makes the adhesive significantly tougher and more durable.

• Boosts heat and water resistance: Essential for shoes exposed to varying temperatures and moisture, preventing bond failure.

• Enhances Overall Durability: Makes the bond more resistant to wear, tear, and chemicals, extending the life of the shoe.

• Accelerates Curing: Speeds up the drying process, crucial for efficient shoe manufacturing.
