Polyaspartic resins (DSPA-series)
Monolith Chem — Dongsen’s polyaspartic vertical. Key evaluation grades DSPA-420, DSPA-520 and DSPA-1720 are listed first. Each grade is a dedicated page for SEO.
Key grades for formulators
DSPA-420 / DSPA-520 (mid-viscosity) and DSPA-1720 (low-viscosity reactive-diluent class) for coatings and flooring evaluation.
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.
