|---|---|
H-5113 is a moderate-viscosity, high-solids modified IPDI isocyanate prepolymer curing agent.
It appears as a colorless to light yellow transparent liquid at room temperature.
As a key raw material for polyurethane/polyurea production, H-5113 serves as a curing component in UV-resistant two-component polyurea/polyurethane coatings, providing excellent chemical resistance, weather durability, outstanding gloss retention, and superior mechanical properties.
With a moderate NCO content, H-5113 is compatible with various NCO blending formulations and offers a working pot life of up to 120 minutes.
Coating systems formulated with H-5113 are ideal for waterproof wall topcoats, floor waterproof clear coatings, or pigmented coatings, especially suitable for high-solids formulations.
| Item | Typical Value | Test Method |
| Appearance | Colorless to light yellow liquid | Visual Inspection |
| Color (Fe-Co) | < 1 | GB 1722 |
| Equivalent Weight (g/mol) | 688 | Theoretical Calculation |
| Isocyanate Content (-NCO, %) | 5.8 - 6.3 | Theoretical Calculation |
| Relative Density (Water = 1, 25℃) | 1.04 - 1.07 | GB/T 15223-1994 |
