EPA Bans Methylene Chloride: Why Nitride+ Welding Tables are the Smart Alternative

The welding industry is changing.

In 2024, the U.S. Environmental Protection Agency (EPA) finalized a ban on methylene chloride, a chemical commonly used in anti-spatter sprays. As a result, welding shops are being pushed to rethink how they protect welding tables without relying on hazardous chemicals.

What is Methylene Chloride?

Methylene chloride (also known as dichloromethane) is a solvent historically used in anti‑spatter sprays and industrial cleaners.

Why Was Methylene Chloride Banned?

Methylene chloride exposure has been linked to severe health effects when inhaled or absorbed through the skin, especially in poorly ventilated environments. The EPA’s intent of phasing out these sprays was to prioritize worker safety.

Impact on Welding Shops

Without methylene chloride‑based anti‑spatter sprays, shops may face:

Increased weld spatter buildup on tables and fixtures
More frequent cleaning and maintenance
Shortened table life or surface damage
Inconsistent weld surfaces caused by uneven buildup

A Process‑Based Alternative to Anti‑Spatter Sprays

One way welding shops are adapting to the methylene chloride ban is by eliminating the need for chemical anti‑spatter sprays altogether.

Instead of relying on coatings or sprays, some tables use surface treatment to reduce spatter buildup at the source.

Nitriding is a heat‑treatment process that hardens the surface of steel, making it more resistant to impact, wear, and corrosion. When combined with black oxide, the treated surface reduces spatter adhesion—allowing weld spatter to break free and wipe away more easily without damaging the table.

This approach offers several practical benefits for welding environments:

Less spatter sticking to the work surface
Reduced cleaning and maintenance time
Improved surface durability without chemical coatings
Protection that extends into hard‑to‑clean areas, including table holes

Flextur’s Nitride+ welding tables apply this dual‑layer surface treatment across the entire tabletop, helping shops maintain flat, consistent welding surfaces while reducing reliance on hazardous chemicals.

Why Welding Shops Are Moving Away from Anti‑Spatter Sprays

The methylene chloride ban isn’t just a hurdle to overcome; it’s an opportunity to improve your shop.

Reduce reliance on hazardous chemicals
Improve worker safety and compliance
Spend less time cleaning and resurfacing tables
Maintain flat, consistent work surfaces

As welding shops adjust to the methylene chloride ban, table selection becomes more important, especially for durability, flatness, and long‑term workflow. Understanding the engineering considerations when selecting a welding table for automation and precision work can help teams make safer, future‑ready decisions.
