Specifications are based on Dongsen’s current approved product data source.
DXCE-551 can be used to formulate industrial floor coating sealer and primer systems.
Its confirmed application direction is Floor Coatings. Dongsen supplies DXCE-551 as an upstream polyisocyanate raw material / curing agent rather than a finished floor coating.
When to consider DXCE-551: Consider DXCE-551 when developing floor coating sealer or primer formulations that require an MDI-based, solvent-free polyisocyanate raw material.
Confirmed selection signals: MDI-based chemistry, 100% solids / solvent-free construction, viscosity below 100 mPa·s at 25°C, and a confirmed floor coating sealer/primer application direction.
Application fit: Industrial floor coating sealer and primer formulations.
Related grade direction: DXCM-121 may also be reviewed as a related MDI-based grade where formulation requirements differ. Refer to the Technical Data section for confirmed numeric specifications.
Grade-selection support: Contact Dongsen technical support when matching the grade to a specific flooring formulation or process requirement.
Documents: Current technical documentation for DXCE-551 can be requested from Dongsen technical support.
