Modified amino resins for corrosion prevention in organic coatings

Modified amino resins for corrosion prevention in organic coatings Purpose – The purpose of this paper is to study the corrosion protective properties of modified urea and/or thiourea formaldehyde resins for steel surface. Design/methodology/approach – Three 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. Findings – The resins that contain both nitrogen and sulphur have excellent corrosion inhibitive activity compared with that containing nitrogen only. Research limitations/implications – The modified resins were based on urea formaldehyde resin, mixed urea and thiourea formaldehyde resin and thiourea formaldehyde resin, respectively. Practical implications – The 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/value – All the prepared resins show promising results for corrosion protection of steel surfaces. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Pigment & Resin Technology Emerald Publishing
