Is Acetone Safe for Cleaning Epoxy Spray Guns?

← Back to How do you clean an epoxy spray gun?

Choosing the right cleaning agent is key in keeping your epoxy spray gun in good condition. Many wonder if acetone is safe and appropriate for this specific task.

Understanding Acetone for Epoxy Residue

Acetone is indeed effective for breaking down and dissolving uncured epoxy resin. However, while it can clear resin build-up from metal parts, it’s wise to be cautious with plastic components, seals, and gaskets. Acetone’s strong solvent properties may deteriorate certain plastics and rubber materials inside your spray gun, leading to wear or damage over time.

Safer Alternatives for Cleaning

If you’re concerned about compatibility, consider using high-purity isopropyl alcohol as a gentler cleaning agent. Products such as Pure Isopropyl Alcohol 99.9% effectively clean resin residue while being less harsh on sensitive parts. Natural degreasers are also a good choice, especially for routine cleaning and maintenance, as they are designed not to damage surfaces or seals.

When This Matters: Spray Gun Longevity

If your epoxy spray gun contains plastic or rubber components, choosing the right cleaner makes a significant difference. Regular use of harsh solvents like acetone without checking compatibility may result in premature wear. For routine maintenance, opt for isopropyl alcohol or a mild degreaser to ensure your equipment remains in good working order.
