Longphos is a liquid iron phosphating solution designed to produce lightweight amorphous iron phosphate coatings on steel and aluminium alloys prior to painting and coating applications.
By creating a uniform phosphate layer, Longphos provides an excellent foundation for both wet paint and powder coating systems, improving coating adhesion while delivering enhanced under-paint corrosion protection.
Designed for manufacturing, fabrication, and industrial finishing environments, Longphos provides an effective pre-treatment solution for steel and aluminium components before painting or coating.
The phosphate coating helps improve coating performance and extends the service life of treated components by delaying the formation of oxidation and corrosion. Longphos is also ideal as a post-treatment rinse following acid or alkaline pickling and stripping operations, helping prepare surfaces for subsequent finishing processes.
It can also be applied to blasted steel to provide temporary corrosion protection and extend the time available before coating, making it an ideal solution for production environments where components may not be painted immediately.
Longphos is trusted by professionals across industries including:
From fabrication workshops to high-volume production facilities, Longphos provides a reliable and effective solution for preparing metal surfaces for long-lasting, high-performance coatings.
