Frequently Asked Questions
Powder Coating, Plastic Coating, Shot Blasting & Coating Removal
At GT Coatings, we’re often asked about our processes, finishes, and preparation methods. Below are answers to the most common questions about powder coating, plastic coating, shot blasting, and pyrolysis coating removal.
🔧 General Coating Questions
What is powder coating?
Powder coating is a dry finishing process where a fine powder is electrostatically applied to metal and then cured under heat. It creates a durable, high-quality finish that is resistant to chips, scratches, and corrosion.
What is plastic coating?
Plastic coating involves applying a protective plastic layer to metal components. It is often used for:
- Protection against corrosion
- Electrical insulation
- Improved grip and durability
Plastic coating is ideal for items exposed to harsh environments or frequent handling.
What industries do you work with?
We work with a wide range of industries across Newton Aycliffe and the North East, including:
- Manufacturing
- Fabrication
- Automotive
- Construction
🔥 Powder Coating FAQs
How long does powder coating last?
With proper surface preparation, powder coating can last many years, even in demanding environments.
Is powder coating better than paint?
Yes, in most cases. Powder coating offers:
- Greater durability
- Better resistance to wear and corrosion
- A more consistent finish
- Lower environmental impact
What materials can be powder coated?
Powder coating is typically applied to metals such as:
- Steel
- Aluminium
- Iron
🧱 Shot Blasting FAQs
What is shot blasting?
Shot blasting is a surface preparation process that uses abrasive materials to clean and prepare metal surfaces.
It removes:
- Rust
- Old coatings
- Contaminants
Why is shot blasting important before coating?
Shot blasting ensures the surface is clean and properly profiled, allowing coatings to adhere correctly and last longer.
Do all parts need shot blasting?
Most metal components benefit from shot blasting before coating, especially if they have rust, old paint, or surface contamination.
🔥 Pyrolysis (Coating Removal) FAQs
What is pyrolysis?
Pyrolysis is a coating removal process that uses high heat in an oxygen-free environment to break down paint, powder coating, and other materials.
When is pyrolysis used instead of shot blasting?
Pyrolysis is ideal for:
- Complex or intricate parts
- Thick or multiple coating layers
- Hooks, jigs, and fixtures
It can reach areas that blasting may not fully clean.
Does pyrolysis damage the metal?
No — when carried out correctly, pyrolysis safely removes coatings without damaging the base material.
🛡 Plastic Coating FAQs
What are the benefits of plastic coating?
Plastic coating provides:
- Strong corrosion protection
- Impact resistance
- Electrical insulation
- Improved grip
When should I choose plastic coating over powder coating?
Plastic coating is better suited for applications requiring:
- Thicker protection
- Electrical insulation
- Softer or more flexible finishes
