VP METALGUARD 250
VP METALGUARD 250
High-Temperature, Non-Stick & Scratch-Resistant Coating for Metal Surfaces Up to 9H Hardness.
Benefits
Vetro Power METALGUARD 250 is a high-performance nano-ceramic hybrid coating developed for industrial metal surfaces subject to heat, abrasion, and contamination. This sol-gel based coating enhances surface hardness to 9H, delivers excellent non-stick performance, and withstands temperatures up to 250 °C. Applied in micrometer-thin layers, it preserves the underlying substrate while offering long-lasting, easy-clean functionality. Suitable for food processing, machinery, tooling, and high-heat components, METALGUARD 250 is the ideal solution for OEMs, processors, and maintenance professionals seeking reliable protection. The applied layer ranges from approximately 4 to 9 microns and is applied using a spray process. It is important to note that this product requires subsequent thermal curing.

Open or Close What level of surface hardness does VP 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?
VP 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 VP 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.
Open or Close Is thermal curing required after application?
Yes. The coating requires heat curing to achieve full crosslinking and durability, either at 215 °C for 60 minutes or 250 °C for 15 minutes.
Open or Close Can the coating be diluted before application?
Yes. METALGUARD 250 may be diluted with butyl acetate up to a 1:5 ratio to adjust viscosity and improve sprayability.
Open or Close What is the coverage rate of the coating?
Coverage is approximately 10-12 m² per liter when undiluted, and up to 60 m² per liter when diluted 1:5.
