Starch is one of nature's major renewable resources and a mainstay of our food and industrial economy. Basic consumer necessities such as paper and textiles are major uses for corn starch in sizing, surface coating and adhesive applications. Corn starches, and their cousins dextrins (a roasted starch), are used in hundreds of adhesive applications. Special types of starches are used in the search for oil as part of the "drilling mud" which cools down superheated oil drilling bits. Other key uses of starch in American industry are as flocculating agents, anticaking agents, mold-release agents, dusting powder and thickening agents.
