SMART MATERIALS 1. Introduction The primary characteristic of a ‘‘smart material’’ is that it has the ability to respond to external stimuli in a technically useful and technically controlled way. The words ‘‘technically useful’’ and ‘‘technically controlled’’ are emphasized since all materials respond to external stimuli of some sort or other (as a simple example‚ all materials respond to temperature by changing their volume)‚ however‚ to be considered a ‘‘smart material’’ the response must

RAW MATERIAL AND SOURCES OF AVAIBILITY The paint industry is raw material intensive. Paint involves the mixing of various raw materials in various proportions. The raw materials are of a wide variety. On an average‚ raw materials account for 60% of net sales (industry average). In case of small-scale units it forms up to 70% of the net sales. Raw materials are divided into three major groups‚ namely‚ pigments (titanium dioxide‚ zinc oxide etc.)‚ solvents (mineral turpentine) and resins and
