How Long Does It Take to Strip Powder Coating and E-Coat? A Complete Guide
One of the most common questions we hear from manufacturers, powder coaters, and industrial finishers is:
“How long does it take to strip powder coating or e-coat using Greensolv solutions?”
The short answer:
Anywhere from 30 minutes to several hours, depending on coating thickness, layers, temperature, and bath cleanliness.
Here’s a clear breakdown to help you plan production cycles more efficiently.
Standard Powder Coatings & E-Coats: 30–60 Minutes
Using Greensolv’s three precision-formulated immersion stripping solutions—
-
SteelStrip
-
AlumiStrip
-
AeroStrip
standard powder coatings and typical e-coats are fully removed in:
⏱ 30 to 60 minutes at 185°F (85°C)
This timing applies to most common industrial coatings, making Greensolv’s solutions an ideal choice for fast turnaround and consistent results.
Multi-Layer Coating Systems: Up to 2 Hours
If your parts have a layered system consisting of:
-
Primer
-
Top coat
-
Clear coat
…expect a longer dwell time.
⏱ Up to 2 hours for a full clean removal
Multi-layer systems take more time because each layer has different hardness characteristics and chemical resistance levels.
Stubborn or High-Performance Coatings: 4–8 Hours
Some coatings simply take more time, such as:
-
High-durability architectural coatings
-
Industrial primers designed to resist chemical attack
-
Thick automotive layers
-
Burned-on or aged coatings
For these tough systems:
⏱ Plan 4–8 hours for complete stripping
These long cycles are typically done overnight to optimize workflow.
How Many Batches Can You Strip Per Day?
When planning your production schedule, here’s a helpful benchmark:
2-hour cycle = 5 batches per day
During a standard 8-hour shift, you can typically run:
-
4 batches during the workday
-
+1 overnight batch for maximum efficiency
This keeps your workflow predictable and helps you plan throughput with confidence.
Temperature: Your Most Important Efficiency Lever
Stripping speed is highly temperature-dependent.
A simple rule of thumb:
A 20°F (≈11°C) temperature increase cuts stripping time in half.
Example:
-
165°F = 2-hour strip time
-
185°F = 1-hour strip time
Maintaining the recommended temperature is one of the easiest ways to improve productivity without changing chemistry.
Solution Cleanliness Matters
Hot-bath immersion stripping is extremely reliable, but only if your solution is well maintained.
A clean, well-filtered bath ensures:
-
Faster and more predictable stripping times
-
Less sludge buildup
-
Longer solution life
-
Consistent batch-to-batch performance
Regular maintenance maximizes chemical efficiency and keeps your production running smoothly.
Reliable, Predictable, and Efficient Paint Stripping
Whether you’re removing powder coating, e-coat, or multilayer systems, Greensolv’s chemical stripping solutions deliver:
-
Fast cycle times
-
Consistent results
-
Predictable scheduling
-
Lower labor requirements compared to blasting or sanding
If you’re aiming to increase throughput or streamline your stripping process, Greensolv can help.
