PHOSPHATING PLANT OR PRETREATMENT

Why use pre-treatment?
The performance of all paint and powder coated finishes depends on the correct preparation of the metal substrate. Failure of coatings in service with problems such as corrosion and blistering are nearly always caused by inadequate pretreatment.
The pre-treatment is often more important than the final finish. As well as providing corrosion protection pre-treatment can offer improvements in wear resistance and other valuable properties. The most widely used pretreatment is known as “Phosphating”.
