Abstract

PurposeThe purpose of this paper is to study the corrosion protective properties of modified urea and/or thiourea formaldehyde resins for steel surface.Design/methodology/approachThree butyl alcohol modified amino resins were laboratory prepared. The three modified resins were characterized using thermal gravimetric analysis and infrared; the solid content and refractive index of each were also measured.FindingsThe resins that contain both nitrogen and sulphur have excellent corrosion inhibitive activity compared with that containing nitrogen only.Research limitations/implicationsThe modified resins were based on urea formaldehyde resin, mixed urea and thiourea formaldehyde resin and thiourea formaldehyde resin, respectively.Practical implicationsThe prepared resins were introduced in different coating formulations based on short‐oil alkyd resin, medium‐oil alkyd resin and plasticized chlorinated rubber. They were then tested and evaluated for corrosion protection of steel surfaces.Originality/valueAll the prepared resins show promising results for corrosion protection of steel surfaces.
