2K Polyurethane applications
Coatings, sealants, adhesives, tooling resins
Advantages
- excellent dispersion properties
- selectable rheology (free-flowing to non-sagging)
- easy processing
- good tensile strength and tear resistance
- good elasticity/compression set
- good abrasion resistance
- good chemical resistance, especially against acids
- good water resistance
- also suitable for food contact and drinking water applications (as per BfR and FDA regulations)
