FEATURES & APPLICATIONS
XYlink ML-200 is a liquid aromatic diamine with similar molecular structure to MOCA. It could be looked as a chemical modified MOCA and can be mixed with NCO-capped prepolymer at lower temperature, showing better operation performance than MOCA. ML-200 reacts faster than MOCA.
XYlink ML-200 is mainly used as chain extender in spray polyurethane-urea systems. ML-200 could be used in TDI-based casting PU elastomers when it is blended with low reactivity chain extender. The PU elastomeric products cured with XYlink ML-200 have good properties.
It can also be used in PU coatings, adhesives, microcellular elastomers.
XYlink ML-200 is also a good curing agent for epoxy resins.
XYlink ML-200 might become somewhat frozen if stored at a lower temperature for a long time, warm it before use.


PACKAGING
20kg, 50kg and 200kg net weight in galvanized iron drum or plastic drum.


STORAGE
XYlink ML-200 is easy to oxidize, it should be stored in an airtight environment to prevent contacting directly with air, oxygen and sunlight. Keep the container well sealed after using and fill nitrogen inside.
The quality guarantee period is 1 year. Even though the product exceeds the expiration date, it could also be used if it is qualified by testing.
