DST-CHEMICALS has various water-based agents under the brand name DST-PAS. The products give corrosion protection to metal substrates. The products differ as they should be used for specific metal types, finishing and passivation requirements. The durability of the corrosion protection always depends on • The metal items’ purity before passivation • The quality of raw water used for the passivation bath • The concentration of any salts which have accumulated in the bath • Metal alloy • Humidity and temperature at subsequent storage • the air's content of chloride, sulphuric dioxide and nitric oxides during storage
