Usage of Unilink 4200
1. Polyurethane Curing & Chain Extension Agent**
Special secondary aromatic diamine chain extender exclusively for MDI-based polyurethane systems, featuring low activity and long pot life.
Delays rapid curing reaction effectively, solves the short operation time defect of traditional fast-curing amine agents, suitable for manual and mechanical pouring processes.
Improves crosslinking uniformity, tensile strength, tear resistance and overall mechanical stability of polyurethane products.
2.PU Elastomer & Foam Modifier**
Core functional material for polyurethane elastomer, microcellular foam, flexible foam and rigid foam manufacturing.
The sec-butyl branched structure provides internal plasticization effect, endowing finished products with excellent low-temperature toughness, compression resilience and surface smoothness.
No precipitation or migration after curing, significantly improving aging resistance and long-term service performance of PU materials.
3.Fine Chemical Synthetic Intermediate**
High-purity fine chemical intermediate for synthesis of high-end polyurethane coatings, waterproof sealants, adhesive materials and polymer modifiers.
Low moisture sensitivity and excellent compatibility with various polyols and additives, ensuring stable reaction and consistent product quality.
Widely applied in industrial polymer customization, new material research and high-performance PU formula development.
