Abstract


Alkyd paints possessing anti – corrosive property on mild steel were prepared using Isiala Oparanadim clay as an extender. The clay which consisted mostly of inert oxides (SiO2 and Al2O3) was calcined at 850oC, sieved to 75 µm particle size, treated with 3M, and 1M HCl and incorporated into alkyd paints at 0 to 80 wt.% extender contents. The surface -, and through – dry time of the formulated paint samples were satisfactory and followed the order:  3M HCl treated clay > 1M HCl treated clay > calcined clay. The paint samples exhibited good adhesion, paint dry film thickness and impact strength, and which contributed to the anti – corrosive property of the paints. While the performances of the formulated paint dry films in 2 % NaCl were good and which attested to their anti – corrosive property, the performances in 2% H2SO4 and 2% NH3 varied depending on clay treatment. This study has highlighted the utility of treated Isiala Oparanadim clay in formulating anti – corrosive alkyd paints for the protection of steel in salty environment, a property which should justify the use of the clay in the surface coatings industry.
