Modified Isocyanate Crosslinker BN-PC02-H00 is a high-performance crosslinking agent designed to enhance cohesion, binding force, and film uniformity in water-based systems. Compared with conventional emulsion or powder crosslinkers, this product offers better dispersion, higher uniformity, and easier application, resulting in improved overall performance of the finished product.
| Performance | Value or State |
|---|---|
| Appearance | Colorless to pale yellow liquid |
| Viscosity (25 °C) | 20–50 mPa·s |
| pH (25 °C) | 7–9 |
| Residual NCO (%) | 0 |
| Solid Content (%) | ≥ 33 |
| Hazen (Color) | ≤ 50 |
| Solubility | Soluble in ester and alcohol solvents |
The modified isocyanate crosslinker significantly improves the cohesion and binding force of coatings and functional films. It disperses more evenly than traditional emulsion or powder products commonly used on the market, leading to stable performance, smooth film formation, and enhanced durability.
Test Results
| Name | Dosage | Test Result |
|---|---|---|
| Modified isocyanate crosslinking agent | 3% | No color fading after complete water washing |
Explanation:
The product exhibits strong color-fixing capability, significantly improving the adhesion of color paste on textiles and reducing fading caused by water washing. This enables long-lasting color fastness.
Test Conditions:
Fabric: Cotton cloth with standard whiteness
System: Aqueous color paste + PU high-gloss denim transparent pulp
Color fixative dosage: 3%
Fixation temperature: 80–120 °C
Fixation time: 10 minutes
Water washing temperature: 60 °C
Water washing time: 2 hours
Detergent: Standard soap
Performance Evaluation
| Dosage | Water Resistance | Alcohol Resistance | Film Transparency & Smoothness |
|---|---|---|---|
| 10% | ≥ 7 days | ≥ 3 days | Good |
Notes:
At a 10% addition level, the sample was immersed in 50 ml of water. After 7 days, the paint surface remained smooth with no cracking.
At a 10% addition level, the sample was immersed in a 60% ethanol solution. After 3 days, the paint surface remained smooth with no cracking.
