FloorSathi DuraBuild 400 Heavy-Duty Epoxy
DuraBuild 400 is a four-component solvent-free epoxy resin screed engineered for extreme mechanical abrasion, forklift impact, and industrial fluid resistance.
Engineered with 100% Novolac epoxy chemistry offering extreme cross-linking density to survive 98% Sulphuric Acid, Hydrochloric Acid, aromatic solvents, and harsh alkalis. Engineered for high-load industrial production bays, warehouses, and hygienic cleanrooms requiring absolute mechanical durability, jointless hygiene, and chemical resistance.
FloorSathi thermosetting matrices are chemically formulated to deliver continuous mechanical resilience, chemical impermeability, and certified slip safety.
Eliminates all grout lines and construction cracks where dust, washwater, and bacteria colonize. Conforms to cGMP and US-FDA cleanroom standards.
Withstands severe mechanical shear, 5-ton solid-wheel forklift fleets, and heavy steel pallet impacts with compressive ratings up to 85 N/mm².
Zero-porosity cross-linked resin prevents penetration of mineral acids, caustic alkaline sanitizers, motor engine oils, and hydraulic fuels into concrete.
Accelerated molecular cure returns floor to light foot traffic within 36 Hours, substantially reducing operational downtime during installation.
Explore cross-section layer structure, ASTM laboratory testing, chemical exposure chart, and laying methodology.
Each layer chemically bonds to the preceding matrix via functional reactive groups, producing a monolithic molecular structure impervious to delamination.
