Products for treating galvanised parts with microcrystalline process that provide the highest possible pre-treatment quality before painting, due to the extreme fineness and special composition of the microcrystals (less than 10μm) that form the phosphate layer. This technology makes it possible to achieve and exceed 1,000 hours of salt fog chamber on hot or cold galvanised parts together with paint, and is particularly suitable for outdoor applications that must withstand harsh weather conditions where the process can work at ambient temperatures or at 60 ºc
