Description

The PICA GEL Tube Marker is a high-permanence gel marking pen that writes on virtually all surfaces with exceptional adhesion — including metal (including rusty or oily steel), glass, ceramics, plastic, rubber, and wet surfaces. The gel formulation is particularly notable for its chloride-free composition, making it safe for use on stainless steel and other metals where chloride contamination can cause stress corrosion cracking — an important consideration in food processing and pharmaceutical electrical installations.
The PICA GEL withstands temperatures up to 1000°C, making it appropriate for marking pipes, heating elements, and equipment that will be operated at elevated temperatures after marking. This high-temperature resistance significantly extends the range of surfaces on which a permanent mark can be achieved compared to standard ink markers.
For electricians working in industrial, food processing, and specialist environments where standard markers fail — due to oily surfaces, extreme temperatures, or material compatibility requirements — the PICA GEL provides a marking solution that genuinely works across this challenging range of conditions.
