Chemical-Resistant Novolac Epoxy Flooring
A highly cross-linked novolac epoxy floor system for concrete exposed to aggressive acids, alkalis, solvents and concentrated process chemicals.
- Highly Cross-Linked Novolac Resin
- Broad Chemical Resistance
- Seamless Containment Surface
- High-Build Concrete Protection
Product Introduction
Chemical-resistant novolac epoxy flooring uses a highly cross-linked resin structure to withstand chemicals that can soften or rapidly stain general-purpose epoxy. It is installed as a high-build multi-coat system or as a sealed aggregate-broadcast topping, depending on traffic and traction needs. The resin is carried over prepared concrete, coves, plinths and containment upstands to limit exposed leakage paths. Final resin selection is based on the actual chemical, concentration, exposure temperature, contact duration and cleaning regime rather than a generic acid-resistant claim.
Key Features
Multiple high-build coats reduce pinhole risk and form a continuous liquid barrier over prepared concrete.
The system can protect horizontal floors, coves, plinths and containment upstands with one compatible resin family.
Aggregate broadcast options add traction and mechanical depth where chemical splash combines with trolley traffic.
Customer Product Concerns
Chemical exposure is defined by concentration, temperature and contact time; a coating that survives a brief splash may not tolerate warm continuous immersion.
Concentrated acid softens or discolors a standard general-purpose epoxy.A higher-cross-link novolac epoxy is selected against the known chemical concentration and exposure temperature.
A pinhole allows liquid to reach concrete and spread beneath the coating.Primer, stripe coats at details and multiple high-build layers close pores before the floor enters service.
Leakage follows the floor-wall joint outside a containment area.The resin lining continues over a formed cove and upstand to remove the exposed corner seam.
One generic formulation is specified for acids, caustics and solvents with different attack mechanisms.The formulation and film build are chosen from a chemical-resistance matrix for the actual process inventory.
Typical Applications
Chemical dosing and formulation roomsBattery storage and charging areasWastewater treatment spacesLaboratory chemical storesSecondary containment and bund floors
Technical Parameters
Typical construction ranges for a high-build novolac epoxy floor and containment lining are listed below.

| Thermal Conductivity | Typically 0.25–0.42 W/(m·K) for the cured novolac epoxy layer |
| Surface Finish | Smooth high-build gloss or sealed slip-resistant broadcast finish, commonly gray |
| Joint Type | Primer and multi-coat novolac lining with stripe-coated penetrations, coved upstands and chemically sealed joints |
| Customization | Available based on the intended application and operating environment. |
