Paint formulation based on deodorizer distillate based alkyd resin and metallophthalocyanines

Abstract

A novel study was carried on paint formulation based on alkyd resin and metallopthalocyanines. Alkyd Resin was synthesised using deodorizer distillate, which is a source of fatty acids that are included in the resin formulation. The distillate is generally cheaper as compared to soya bean oil that is being used at the moment. It is a by-product produced during the deodorization process of edible oil refineries. The resin reaction was stopped at an acid value of 9.6 mg of potassium hydroxide per gram of alkyd resin. Metallopthalocyanes, Copper(II)Phthalocyanine and Cobalt(II)Phthalocyanine were synthesised as pigments in paint formulation. All the synthesised products were characterised using Fourier Transform Infrared spectroscopy (FT-IR), Ultraviolet visible spectroscopy (UV- Vis) and thermal gravimetric analysis (TGA). The synthesised alkyd resin was linked covalently with cobalt(II)tetraamino phthalocyanine and non-covalently with copper(II) phthalocyanine. The pigments were dispersed in the resin with the aid of a solvent xylene in order to produce two paints based on the two different metallophthalocyanines. The formulated paint products were exposed to sunlight in solution form for photo degradation studies. The wavelength of highest absorbance was found to be 680 nm and no new bands were observed signifying the stability of the formulated paints.
