Application of coatings is one of the most widely utilized methods of corrosion protection, as it is economical and can be applied easily. Water-borne anti-corrosion coatings have gained a lot of attention for the protection of metals as they keep the emission of VOCs to a minimum.

PU coatings are preferred in metals to control corrosion as they are highly flexible and have suitable adhesion properties. When used for metal coatings, PUs form a glossy, thin film which has good performance towards weathering. These durable coatings are highly resistant to corrosion, chemicals and abrasions.
