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 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.

XY-OCA is an aromatic amine compound, its color becomes dark gradually when being exposed to air. It has slightly ammonia odor and may explode when it is encountered with open flame. It can produce poisonous nitrogen oxides and chlorine gas with the high thermal decomposition.
