Vetro Power METALGUARD 250
Vetro Power METALGUARD 250: Industrial Non-Stick, High-Temperature Coating for Metal
High-Temperature, Non-Stick & Scratch-Resistant Coating for Metal Surfaces Up to 9H Hardness.
Benefits
Vetro Power METALGUARD 250 is a solvent-based, heat-resistant non-stick coating for metallic surfaces. It bonds to pre-treated steel, sandblasted steel, and stainless steel, forming a thin, durable film that withstands continuous operating temperatures up to 250 degrees C.
- Non-stick surface performance: Prevents organic and process material from adhering to treated components, making cleaning faster and reducing production downtime.
- Heat resistance up to 250 degrees C: Maintains coating integrity under sustained thermal exposure. The curing process itself (215 degrees C for 60 minutes, or 250 degrees C for 15 minutes) sets the coating to handle real industrial heat conditions.
- Surface hardness up to 9H: Scratch resistance of 4-5 Mohs before curing develops to up to 9H hardness on the finished surface, based on internal testing.
- Thin, precise film thickness: Applied by spraying, the dry film is 10-15 microns thick. When applied by dipping or flooding, the film is 2-10 microns, which preserves component tolerances for precision parts.
- High coverage efficiency: Used undiluted, one litre covers 10-12 square metres. When diluted up to 1:5 with butyl acetate, coverage extends to up to 60 square metres per litre, making it cost-effective at scale.
- Suited to demanding industrial environments: Designed for machine components exposed to heat, food processing equipment where non-stick properties matter, and mechanical engineering applications where surfaces take repeated thermal and mechanical stress.
- Multiple application methods: Can be applied by spraying (recommended), dipping, or flooding, allowing it to work on both flat surfaces and complex geometry components.

Open or Close What level of surface hardness does Vetro Power METALGUARD 250 provide?
The coating increases metal surface hardness up to 9H pencil hardness, offering excellent scratch and abrasion resistance compared to untreated metal substrates.
Open or Close What is the maximum operating temperature of the coating?
Vetro Power METALGUARD 250 withstands continuous heat exposure up to 250 °C, making it suitable for high-temperature industrial applications.
Open or Close Does the coating offer non-stick and easy-clean properties?
Yes. The nano-ceramic surface delivers excellent non-stick behavior, reducing material build-up and enabling easy cleaning and lower maintenance.
Open or Close Which substrates are compatible with this coating?
It is ideal for stainless steel and other industrial metal substrates that have been properly surface-prepared, such as sandblasted or mechanically treated metals.
Open or Close What are the typical industrial applications?
Common applications include food processing equipment, heat-exposed machine components, rollers, molds and dies, tooling, and packaging machinery.
Open or Close How is Vetro Power METALGUARD 250 applied?
The coating is typically applied using a spray process (recommended), but dip or flood application methods are also possible.
Open or Close What is the recommended coating thickness?
The dry film thickness ranges from 2–10 µm for dip coating and 10–15 µm for spray application, preserving substrate dimensions.
