FEATURES &APPLICATIONS
XYlink DMD230 is a kind of aliphatic aspartic-ester containing two secondary amino groups. It is recommended used to formulate solvent-free or high solid 2-K spray polyurea or polyaspartic ester coatings. Compared with common primary-amino raw material, DMD230 has a moderate reactivity, so it has good operating performance. The coatings can be applied with machine, also can be brushed. Thick coating layer can be formed successfully.
The aliphatic coating film has good surface effect, good flexibility and mechanical properties, good corrosion resistance, weatherability and yellowing resistance.
XYlink DMD230 is recommended mainly used with aliphatic isocyanate (e.g., HDI trimer) to prepare polyaspartic ester polyurea coatings. This product is suitable for decorative topcoats based on the conventional spray polyurea elastomer. The application fields include anti-corrosive coatings for the bridge and outdoor building, providing long lasting protection for the concrete. It can also be used for furniture decorative paint, industrial floor coatings, top-coating for sport ground, protective coating for fan blades, composite coating for helicopters, and other high-end application fields.
