As an accredited Aliphatic Polyisocyanate Crosslinkers factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Aliphatic Polyisocyanate Crosslinkers are packaged in 25 kg tightly sealed metal drums, labeled with product details, hazard warnings, and handling instructions. |
| Container Loading (20′ FCL) | 20′ FCL container loads about 16 metric tons of Aliphatic Polyisocyanate Crosslinkers, typically packed in 200 kg drums or IBC totes. |
| Shipping | Aliphatic Polyisocyanate Crosslinkers should be shipped in tightly sealed, corrosion-resistant containers, protected from moisture and direct sunlight. Transport must comply with relevant hazardous materials regulations, using appropriate labeling and documentation. Ensure the cargo is secured upright during transit, and segregate from incompatible substances such as water, alcohols, amines, and acids. |
| Storage | Aliphatic Polyisocyanate Crosslinkers should be stored in tightly sealed containers in a cool, dry, and well-ventilated area, away from direct sunlight, heat sources, moisture, and incompatible materials like amines and alcohols. Avoid freezing temperatures. Ensure proper labeling and keep containers upright. Use only in areas with appropriate spill containment and ensure easy access to safety data sheets and protective equipment. |
| Shelf Life | Aliphatic polyisocyanate crosslinkers typically have a shelf life of 12–24 months when stored in tightly closed containers at recommended conditions. |

High Purity: Aliphatic Polyisocyanate Crosslinkers with high purity (≥99%) are used in automotive clear coats, where they provide superior gloss and enhanced UV resistance. Low Viscosity: Aliphatic Polyisocyanate Crosslinkers with low viscosity (<1000 mPa·s) are used in industrial wood coatings, where they enable smooth application and leveling for even film formation. Standard Molecular Weight: Aliphatic Polyisocyanate Crosslinkers with standard molecular weight (600–1200 g/mol) are used in protective metal coatings, where they deliver durable mechanical strength and improved corrosion resistance. Stable at High Temperature: Aliphatic Polyisocyanate Crosslinkers with high stability temperature (up to 80°C) are used in exterior architectural coatings, where they ensure long-lasting weatherability and gloss retention. Fast Drying: Aliphatic Polyisocyanate Crosslinkers engineered for rapid curing are used in automotive repair paints, where they significantly shorten turnaround times and minimize dust contamination. Colorless Grade: Aliphatic Polyisocyanate Crosslinkers of colorless grade are used in clear plastic coatings, where they maintain substrate transparency and prevent discoloration over time. Low Monomer Content: Aliphatic Polyisocyanate Crosslinkers with low residual monomer (<0.5%) are used in food-contact compliant coatings, where they reduce migration risk and enhance product safety. Fine Particle Dispersion: Aliphatic Polyisocyanate Crosslinkers with fine particle size (<100 nm) are used in waterborne coatings, where they improve compatibility and film uniformity. High Solid Content: Aliphatic Polyisocyanate Crosslinkers with high solid content (>85%) are used in high-build floor coatings, where they enable thicker application with fewer coats. Hydrolysis Resistance: Aliphatic Polyisocyanate Crosslinkers with superior hydrolysis resistance are used in marine coatings, where they extend coating life in humid and saline environments. |
