Ambient cured tartaric acid modified oil fatty amide anticorrosive coatings

A novel tartaric acid modified fatty amide diol (TAFA) was synthesized through the condensation polymerization of N,N-bis(2-hydroxy ethyl) linseed oil fatty amide and tartaric acid (TA). The structural elucidation of the TAFA resin was carried out by FT-IR, H-1-NMR, and C-13-NMR spectroscopic techniques. The physico-mechanical and physico-chemical characterization of the resin were done by standard methods. TAFA, when further reacted with butylated melamine formaldehyde (BMF) in different phr (part per hundred part of resin) (TAFA-BMF) was found to cure at room temperature. The TAFA-BMF cured system was subjected to spectroscopic analysis to ascertain the structure and curing scheme of the same. The thermal studies of these resins were carried out by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The physico-mechanical properties and anticorrosive performance of TAFA-BMF coatings were evaluated by standard methods. The effect of TA and BMF on thermal stability, physico-mechanical and anticorrosive properties of resins was also investigated.
