Performance Test Results

DuPont Multi-Coat Systems Offer Better Value than the Competition Over the years, DuPont has developed many coating technologies for the consumer segment that prove to be very successful for industrial applications.  The old versions of SilverStone*, SilverStone Supra*, and 857-line have been replaced by a new generation of superior coatings from DuPont.  These products continue to demonstrate exceptional levels of durability, release, and thermal resistance in a number of industries such as food processing, packaging, office automation, and molding.                                                  Series 1 (459N-11xxx line) and Series 4 (459N-411xx) DuPont recently tested their Series 1 and Series 4 coating lines against a well established competitive three coat system.  The results confirmed our feelings that the DuPont products are an excellent choice for applications that require high levels of durability, release, and thermal resistance.  More importantly, we learned that the Series 1 products offer exceptional performance at a considerably lower price than its competitive alternative.  If you have not utilized these products, we encourage you to evaluate them on your next project.  Below is a summary of the relative test results.  Please contact Chris Dohl at Intech Services for a copy of this data in .pdf format.  Chris can also provide you with more specific test results on these excellent Dupont Coatings.    Performance Tests In addition to tests that determine the quality of coating application, DuPont uses a set of performance tests. These tests show coating performance, and are therefore useful benchmarks for comparison with existing coatings, as well as in the development of new ones.

Results dependent on coating application and substrate preparation. Sample Preparation: Cold rolled steel panels were prepared and coated according to fact sheet recommendations. DFTs were approximately 1.5 mil. Taber Abrasion The Taber Abrasion test method determines the resistance of coatings to abrasion. This test method is normally used to rank coatings rather than placing significance on the numerical values themselves. The coating is subjected to a set number of cycles per ASTM D 4060-95 and the weight loss is measured and normalized to remove variability due to film thickness differences. Coefficient of Friction Coefficient of Friction testing determines how “slippery” a coating is. A weight is pulled across a coating’s surface at a specified speed. The force required to move the weight from a standstill (static) as well as to continue motion (kinetic) is measured, resulting in coefficient of friction values for the two cases. The lower the value determined, the more “slippery” the coating surface.
