2 For almost three-quarters of a century, Turco Products has been recognized around the world as the market leader in bringing innovative, cost-effective chemical technologies to bear on difficult processing problems in the aircraft/aerospace manufacturing, maintenance and refurbishment industries. Now, as the world moves into the twenty-first century, the focus of those industries is narrowing inexorably to those chemistries that will offer not only those same advantages of performance and efficiency, but, at the same time, will protect worker health and safety, will minimize environmental impact, and will allow industry to operate as a good neighbor, whether in a rural or urban area. Turco Products is proud to have been a leader in promoting that narrow focus and in discovering and developing new technologies to stand up to that focus. This brochure describes some of the results of that continuing commitment. Each of the products described represents the fruit of a concentrated dedication of research effort, capital resources and proprietary knowledge: the solution of a vexing processing issue. This may have resulted in the elimination of a chlorinated solvent, a HAP or a VOC; or a replacement of a toxic or carcinogenic chemical with one more benign; or the incorporation of ingredients easily removed or destroyed for ready disposal; or a significant reduction in volatility; or a significant increase in flash point; or any number of innovative developments to make the process Environmentally Advantaged. We are happy that we have been able to lead for part of the way on this journey to a more Environmentally Aware future.
