ADDOLINK® 1604

Product Description

ADDOLINK® 1604 is a high-performance chain extender and crosslinking agent for use with PUR prepolymers in the production of polyurethane hot cast elastomers. It provides significantly longer casting times compared to conventional amine crosslinking agents, enabling controlled processing and the manufacture of large-volume components. The extended reaction window supports precise manual and industrial processing while maintaining consistent elastomer performance. 

THESE SPECIAL FEATURES MAKE THIS PRODUCT SO SUCCESSFUL   

• Significantly longer casting and reaction times compared to other amine crosslinking agents  
• Enables manufacturing of large-volume PUR hot cast elastomer articles  
• Controlled processing window  
• Low viscosity in molten state for efficient mixing and flow  
• High flash point supporting safe industrial handling  
• Stable storage performance with up to 24 months shelf life under recommended conditions 

THE MOST COMMON AREAS OF APPLICATION  

• Production of high-quality PUR hot cast elastomers  
• Crosslinking and chain extension in combination with PUR prepolymers  
• Manufacturing of large cast polyurethane components requiring extended processing times  
• Manual casting processes benefiting from longer reaction windows  
• Industrial polyurethane systems
