DXB-3375E is a solvent-based blocked HDI trimer crosslinker designed for use in 1K baking coating formulations.
Final suitability should be evaluated according to the actual resin system, substrate, bake profile and target coating requirements.
DXB-3375E can be considered when formulating solvent-based 1K baking coating systems that use blocked HDI trimer crosslinker chemistry.
The established application scope includes industrial topcoats, primers, textile coatings, printing-paste crosslinking and other baking coating formulations.
Review the Technical Data together with your resin system, substrate and actual bake profile. Because the current deblocking-temperature value is under source verification, confirm the required bake window with Dongsen before final grade selection.
DXB-3375D and DXB-3370G may also be reviewed as same-family blocked HDI trimer grades where a different formulation or processing requirement applies.
