Isocyanate (NCO) Terminated Polyurethane Systems
Overview of Isocyanate-Terminated Polyurethane Prepolymers
Isocyanate (NCO) terminated polyurethane prepolymers are essential in creating high-performance polyurethane systems. These prepolymers result from the reaction between polyols and isocyanates. The isocyanate groups in these systems are characterized by their terminal NCO groups, which can include materials such as MDI (methylenediphenyl diisocyanate), TDI (toluene diisocyanate), or aliphatic isocyanates.
Polyol Options:
- Polyester
- Polyether
- Polycarbonate
Key Features of Isocyanate-Terminated Polyurethane Systems:
- Physical Resistance
- Chemical Resistance
- Hydrolysis Resistance
- UV Resistance
- Wear Resistance
- Elastic Recovery
The physical and chemical properties of these polyurethane systems are significantly influenced by the polymer structure. The ratio between the soft segments (from polyol chains) and the hard segments (from isocyanate chains) imparts various desirable characteristics to the final polymer.
Types of Prepolymer Resins:
- Solvent-Based Resins
- Solvent-Free Resins
Application Versatility: Our isocyanate-terminated prepolymer resins can be used in diverse applications, including:
- Coatings
- Adhesives
- Impermeable Systems
- Elastomers
These resins are available in both two-component systems (with polyol or amine components) and one-component moisture-curing systems. For tailored solutions with specific reaction rates, functionalities, and solvent contents, contact our team to discover the ideal prepolymer resin for your needs.
