Epoxy Binders and Performance Treatments for Textiles/Nonwovens

EPI-REZ™ waterborne epoxy resins are combined with water-compatible curing agents to bond fibers and enhance the performance of textile and nonwoven substrates. Specific performance improvements include:

Higher strength
Chemical resistance
Thermal resistance

Available system options help meet many regulatory requirements, such as:

Low or zero volatile organic compounds (VOCs)
Compositional compliance for food and water applications
No added formaldehyde

Formulations are most frequently heat-cured. Water-compatible curing agents include aliphatic amines, cycloaliphatic amines and dicyandiamide. Epoxy catalysts, such as tertiary amines and imidazole compounds, may also be used.
