Application of Factorial Design to the production of Texcoat paint

Abstract

This research paper s centered on the application of factorial design in the production of texcoat paint. Three varying factors Calcium Carbonate (x1), polyvinyl acetate(x2) and Titanium dioxide(x3) was chosen from the raw materials and the rest (raw materials) remain constant in standard quantity. Eight different experimental runs with varying factors of 20% each, in quantities of Polyvinylacetate. Titanium dioxide and Calcium carbonate were formulated and carried out. The products obtained were analyzed for weight, viscosity and specific-gravity tests. The results obtained shows number 5 run to be the best as its specific-gravity fall is within the standard values of1.42 to 1.52, while its viscosity equals to the standard value of 38 poises. Therefore, improved quality without defect can be formulated when 20% increase in polyvinyl-acetate and 20%decrease, each in Titanium dioxide and Calcium carbonate besides the normal formulation used for this research. Finally, model equations were derived from the result of the factorial design experiment can be used in the production of standard texcote paint.
