Abstract:

The requirements of coatings are increasing day by day for protecting different substrates from various types of stresses. Today, the decorative paints specifically water based paints are in liquid form resulting in increased handling cost. The purpose of this paper is to develop a single component powder putty and powder paint using easily available nonconventional materials. This paper deals with studies in effect of concentration and mode of addition of various components on properties of paint for decorative applications. These powder putty and powder paint formulations have been evaluated and compared with conventional decorative paints. The powder paint formulations have also been evaluated for exterior applications viz. mechanical, thermally insulating and chemical performance properties. The effects of concentration of glass microspheres on properties of powder paints have also been studied. It has been seen that powder putty and powder paint show satisfactory performance as compared to conventional putty paste and liquid paint. The new Paint formulations, added with glass microspheres are found to give very good heat insulation, where temperature difference is 6 to 8% with respect to surrounding temperature and the coating. These products are based on simple and easily available raw materials. The existing equipment /machinery can be used for preparation of these products. Also this new coating is applicator friendly and easy to apply.
