XYlink HER-L is an aromatic diol used as chain extender of polyurethanes. It is a phenylether glycol mixture with 3-hydroxyethoxy-1-hydroxyethylbenzendiether as the main component. It is a homologue of the chain extender HER and could be looked as a liquid version of HER. It is suggested to be warmed above 25℃ to get easy operability, especially in winter. This product is applicable to medium hardness of elastomeric polyurethane products.

XYlink 311 can be applied with hand mixing or automatic mixing of casting equipment for producing polyurethane elastomers. XYlink311 is also used as a thermoreactive curing agent for epoxy resins. Mix thoroughly before use.

XYlink 740M is an aromatic diamine with symmetrical molecular structure and containing ester group. It has similar molecular structure with XYlink P series curing agent, and higher melting point than P series.

XYlink P-1000 serials are aromatic diamine chain extenders or curatives containing flexible ether segment and ester group. The molecular structures of XYlink P series are similar with the XYlink 740M.

As viscous liquids, XYlink P-650 could be mixed with TDI or MDI based prepolymer at room temperature for casting and curing. It is especially suitable for onsite processing due to its easy workability. Their application includes casting elastomers, coatings, adhesives, sealants and sprayings.

XYlink P-250 serials are aromatic diamine chain extenders or curatives containing flexible ether segment and ester group. The molecular structures of XYlink P series are similar with the XYlink 740M.

XYlink E90 is a colorless, low viscosity aliphatic secondary diamine. XYlink E90 has a moderate reactivity due to the secondary amino group and can make the operating process more convenient. It can be used as the only chain extender or mixed with other diamine or diol chain extenders in the preparation of aromatic and aliphatic polyurethane-urea, polyurea with good performance. Its application includes reaction injection molding (RIM), casting elastomers, spray elastomers, coatings, sealants and adhesives, etc. Aliphatic polyurethane-ureas based on XYlink E90 and aliphatic diisocyanate have outstanding color stabilization.

XYlink E-100 is a liquid aromatic diamine chain extender. The reaction speed of XYlink E-100 with urethane prepolymer is several times faster than DMTDA which has similar molecular structure, and faster than MOCA by about 30 times.

XYlink 401 is an aromatic imine-type latent curing agent based on aromatic diamine and ketone/aldehyde. It is a low viscosity liquid, and has good miscibility with -NCO terminated polyurethane prepolymers, and can reduce the viscosity of room temperature curing polyurethane system.
