Polyaspartic systems for global coating markets
Monolith Chem is a Dongsen Chemicals brand — the vertical product line focused on polyaspartic polyurea. Dongsen and Monolith appear side by side: Dongsen hardeners (HDX-100, HDX-1200) pair with Monolith DSPA-series resins — key grades DSPA-420, DSPA-520 and DSPA-1720 — for flooring, waterproofing, anti-corrosion and tile grout.

Key grades for formulators
Featured evaluation grades: DSPA-420 (mid-viscosity, faster), DSPA-520 (mid-viscosity, slower / manual) and DSPA-1720 (low-viscosity reactive-diluent class).
DSPA-420
Mid-viscosity polyaspartic resin for high-solids coatings; faster gel window. Evaluation drop-in for formulators comparing mid-range polyaspartic amine resins in the same performance class.
Featured resinDSPA-520
Mid-viscosity polyaspartic resin for manual / hand-applied polyurea and flooring; longer gel window. Evaluation grade for formulators comparing slower mid-range polyaspartic resins in the same performance class.
Featured resinDSPA-1720
Low-viscosity reactive-diluent class polyaspartic amine resin for high-solids 2K coatings — flooring, anti-corrosion topcoats and industrial finishes. Evaluation grade for formulators comparing low-viscosity / reactive-diluent polyaspartic resins in the same performance class. Confirm viscosity, EW and gel with factory TDS.
