Unilink® 4200
Unilink® 4200 is an aromatic diamine chain extender and curative designed to cross-link polyurethane (PU) elastomers.
Unilink® 4200 is a relatively low reactivity chain extender that can be used in TDI and MDI formulations. This cross linker is great for improving the increasing the tear strength and load bearing of flexible PU foams and will improve the compressive strength of rigid (PU) foams. In addition, Unilink® 4200 allows coatings, sealants, and adhesives that it cures to adhere better and develop smoother surfaces. It has low moisture sensitivity, it is compatible with most polyols and polyurethane chemicals, and is easy to handle and store.
