Tong has partnered with Internationally-renowned PPG Industries, allowing us to offer a specialist paint finish on all mild steel painted equipment. Giving the Bulker unrivalled corrosion resistance, excellent durability and outstanding appearance.
The innovative SPECTRACON® coating pairs a solvent-based epoxy primer with a high-performance finish layer. This ensures surface durability, and the resilient undercoat offers superior anti-corrosion protection should the top finished coating suffer chipping or damage. Giving an additional layer to prevent rust, oxidation or steel tarnishing. The eco-friendly acrylic polyurethane paint has been designed with challenging exterior conditions in mind. It can also withstand direct sunlight, preventing appearance fade and ensuring a long-lasting glossy appearance. Tong’s specialist painted finish can be supplied in any colour to match existing machinery, surroundings or site requirements.
