Abstract
Piperazine-modified fatty amide (PMF) was prepared from N,N-bis(2 hydroxy ethyl) linseed oil fatty amide and piperazine through condensation polymerization. It was further cured with butylated melamine formaldehyde in different phr (parts per hundred part of resin) (PMF-BMF). PMF and PMF-BMF systems were subjected to spectroscopic analysis to ascertain their structure and curing scheme. Thermal studies and curing behavior of these resins were carried out by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The physico-mechanical performance and chemical resistance of PMF-BMF coatings were evaluated by standard methods. The effect of BMF content and curing temperature (ambient and elevated) on aforementioned coating properties was also investigated. It was found that PMF resin with 80 phr BMF cured at 120°C showed the best performance among all compositions.
