Abstract

Natural adhesives are appealing to our present industrial society because they conjure up thoughts of products derived from completely renewable resources, thus offering solutions to the price vulnerability and diminishing availability of the petroleum resource. Sometimes, however, our thought processes are inhibited by the rapid scientific and industrial changes which have occurred over the last few centuries. Going back in history, we soon realize that natural materials have been used as adhesives since at least the time of the Pharaohs. Only in the last hundred years have synthetic-based materials made a significant impact. In fact, it should be remembered that these so-called synthetic materials, which are produced from petroleum or coal feedstocks, in themselves originate from plants and animals. Under the influence of pressure, time and an anaerobic environment, they decomposed to these hydrocarbon sources. This process required tens of thousands of years. Our current energy problems arise because this resource is being depleted in the relative short time period of a few hundred years. By using plant products, the growing cycle can be matched to the time of man’s utilization. If planned carefully, these products then become renewable (in our lifetimes) chemical and energy resources.
