Application solution
Bridge Protection
Protective polyaspartic topcoats for bridge steel and concrete structures.
High crosslink density and UV resistance make polyaspartic topcoats suitable for bridge protection where durability and weatherability matter.
Recommended grades
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.
MonolithDSPA-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.
