Machine shops, plating lines, battery rooms, automotive bays, and chemical containment areas all need flooring that handles more than wheel traffic. Novolac chemistry, ESD systems, and proper containment detailing are the difference between a floor that lasts and a re-coat in two years.
For most warehouse work, thickness drives performance. For manufacturing, chemistry does. A 60-mil standard epoxy will dissolve under aggressive solvents that a 15-mil novolac shrugs off. We spec the resin system first, thickness second.
High-cross-link epoxy with significantly higher chemical resistance than standard bisphenol-A epoxy. The right pick for any environment with regular exposure to acids, bases, solvents, hydraulic fluids, or fuels. Common in metal finishing, chemical processing, and automotive repair facilities.
| Exposure | Standard Epoxy | Novolac Epoxy |
|---|---|---|
| Sulfuric acid (30%) | Fails | Resistant |
| Sodium hydroxide (50%) | Marginal | Resistant |
| Methylene chloride | Fails | Resistant |
| Hydraulic fluid (long-term) | Softens | Resistant |
| Gasoline / diesel | Marginal | Resistant |
For chemical storage areas, transfer zones, and battery rooms — high-build coatings (typically 100–250 mil for severe environments) applied with integral cove and continuous seal to function as the secondary containment barrier required by EPA, SPCC, and most local fire codes.
For electronics manufacturing, powder handling, munitions, and any environment where static discharge is a process or safety risk. Conductive copper grounding grid embedded under a dissipative topcoat targeted at 10⁶–10⁹ ohms surface resistance per ANSI/ESD S20.20.
Continuous coating into and through floor drains, pits, and trenches with no termination joint inside the wet zone. This is where most cheap-bid jobs cut corners and where the failures start.
| Application | Recommended System | Key Property |
|---|---|---|
| General machine shop | High-build epoxy, 40–60 mil | Oil resistance, impact |
| Automotive service bay | Polyaspartic topcoat over epoxy | Rapid cure, hot-tire pickup resistance |
| Plating / finishing | Novolac, 40–80 mil + cove | Acid resistance |
| Battery / charging room | Novolac + acid-resistant cove | Sulfuric acid spill containment |
| Electronics assembly | ESD epoxy system | 10⁶–10⁹ Ω surface resistance |
| Chemical storage | Secondary containment, 100+ mil | EPA / SPCC compliance |
The right system depends on what the floor has to survive. Let's talk.
