FEATURES &APPLICATIONS
XYlink 3767 is an imide-type aliphatic latent curing agent made from an alicyclic diamine and aldehyde/ketone. It has good compatibility with NCO-terminated prepolymer, and rapidly decomposes when it contacts moisture, the generated amino groups react with isocyanate quickly and gel occur. Thus bubbles and holes formed in polyurethane could be avoided which due to a lot of CO2 generated from isocyanate-water reaction.
XYlink 3767 is mainly recommended used for one-component moisture-curing polyurethane(1-K MCU) coating system. It can solve the bubble and pinhole problem of MCU system. It can also be used for one-component polyurethane adhesives, sealant, and two-component polyurethane etc.
XYlink 3767 latent curing agent is an environmentally-benign product. It has low VOC emission and no unpleasant odor in production and processing. The cured polyurethanes have good mechanical properties.
Please determine the appropriate dosage and the storage stability in different MCU system by lab test in advance of industrial application.


PACKAGING
16kg net weight in plastic drum or barrel.


STORAGE
This product is sensitive to moisture. Keep it storing airtight in cool, ventilated, rainproof, sunproof and fireproof places. Keep the container well sealed after using and fill neutral gas (such as nitrogen) to protect from moisture.
The shelf time is 6 months in case of unopened. If stored over shelf life, it can still be useful when the main application properties are qualified by inspecting.
