Artistic Variation in Relative Density Characteristics of an Agro-Organic Based Paint Thickness

Abstract

This research involved determining the thickness of an organic paint in relation to its relative density as caused by variation in clay content in the paint. The paint being a product from agro-organic material bases: Gmelina (Gmelina arborea) seed extract and Teak (Tectona grandis) leaves extract, upon experimentation, the extracts solution was found to have the same density as water but variation set in while modifying its thickness through clay additives. The resultant weight of the solution was found to increase with increase in clay content additive. The paint thickness was determined by testing thirteen paint samples of different relative densities using a test plate of 20 cm x 20 cm cross section area. It was discovered that paint samples with relative density range of 1.040 – 1.05 having thickness range of 0.039 mm – 0.043 mm were in conformity with the standard paint thickness range of 38 microns to 43 microns. It was generalized that the relationship between paint relative density and thickness was “y = 1.3766x + 0.9902” where “y” is paint relative density and “x” is paint thickness. The general equation was found to have R² of 0.9784 which signifies a relatively precise paint thickness prediction.
