Description

Reliable Steel Protection

Würth Zinc Phosphate Primer is a hydrocarbon-based, high-build primer formulated to protect steel structures from corrosion while delivering a smooth, low-sheen finish. It is designed as a general-purpose primer suitable for a wide range of applications in industrial, fabrication, and maintenance environments.

Fast Drying and Efficient

With a drying time of just 20 minutes to touch-dry and 1 hour to fully dry, the primer allows for faster handling and recoating compared to traditional primers. This makes it highly effective in workshop and on-site environments where time is critical.

High Coverage Performance

The product provides a coverage rate of approximately 5.3 m² per litre at 75 µm thickness, ensuring excellent material efficiency. Its strong build and adhesion help create an ideal base for finishing coats.

Versatile Application

The primer can be applied by hand, spray, or airless spray equipment, allowing for flexible use across different projects. For spray applications, up to 10% thinners may be added to achieve optimum atomisation and flow.

Durable and Long-Lasting

With a shelf life of 12 months when stored correctly, Würth Zinc Phosphate Primer offers excellent storage stability. It provides dependable adhesion and anti-corrosive properties, making it suitable for general fabrication, structural steelwork, machinery, and repair jobs.
