Environmental friendly poly(ether-fattyamide) resin composition

摘要

An environmental friendly poly(ether-fattyamide) coating composition for mild steel plates or the like comprises and/or consists of a condensation polymerization product of a fatty diol and an aromatic/cyclic diol and wherein the fattyamide diol is synthesized using rapeseed oil and further cured with an aminoplast resin and a catalyst. The rapeseed oil is combined with a crosslinker such as hexa methoxy melamine formaldehyde, butylated melamine formaldehyde, urea formaldehyde of hydroxyl values of 220-240 mg KOH/gm of resin and curing catalysts. The curing catalyst may be para toluene sulphonic acids, dodecyl sulphonic acids, orthro phosphoric acid in a solvent such as xylene, ethyl methyl ketone, ethylene glycol mono methyl ether and aromatic hydrocarbons. Additional agents such as surfactants, stabilizers, wetting agents, flow modifiers, dispersing agents, adhesion promoters and UV absorbers may be added.

1. An environmental friendly poly(ether-fattyamide) resin composition, said composition comprising a condensation polymerization product of fattyamide diol and an aromatic/cyclic diol and wherein said fattyamide-diol is synthesized using rapeseed oil and further cured with aminoplast resin and an acid catalyst in which said acid catalyst is selected from the group consisting of para toluene sulphonic acid, dodecyl sulphonic acid, orthophosphoric acid and mixtures thereof and wherein said rapeseed oil is combined with a crosslinker selected from the group consisting of hexa methoxy melamine formaldehyde, butalated melamine formaldehyde, urea formaldehyde and mixtures thereof, and wherein said curing catalyst is in a solvent selected from the group consisting of xylene, ethyl methyl ketone, ethylene glycol mono methyl ether, aromatic hydrocarbons and mixtures thereof and which includes additional agents selected from the group consisting of surfactants, stabilizers, wetting agents, flow modifiers, dispersing agents, adhesion promoters, UV absorbers and mixtures thereof.
