 New Product from DuPont - 958-406

958-406 is a PTFE low-bake, solvent-based one coat, which was designed for easy and flexible application combined with a balance of  excellent properties. It offers excellent adhesion, a low friction surface and good corrosion resistance while providing a hard and wear resistant coating for general industrial use. 

958-406 is called "low bake" because it has a bake time of 30 min at 356* F providing full adhesion and excellent performance.  The low-bake capability may allow this product to  be used on substrates such as some plastics and thin gauge metals that cannot typically be coated with high temperature curing coatings.

The material can be applied at a thickness up to 40-50μm per coat, but can be applied thinner if needed, by means of dilution. The material can also be applied in 2 coats to reach a final thickness of ~ 80μm. 

Adhesion on steel and aluminum has been tested by Cross Hatch (ASTM D-3359-92A) and found to be perfect. It was also tested after a Pressure Cooker Test where the cross hatched panel was exposed to a steam at 302° F for 50 hours, and had excellent adhesion. 

Corrosion resistance was tested in Soaking Test under severe conditions of 10% NaCl at 176° F for 100 hours. No blisters, creep, or adhesion loss were observed even when applied on smooth, cold rolled steel. 

Wear resistance was measured by Thrust Abrasion Tester.  The coating reached a typical PV ratio of 18,500 kgf/cm2*cm/s when tested under a speed of 1000mm/sec. The weight loss measured on the Taber Abrasion Tester was 0.0305 g with wheel CS17 loaded with 1000gr and after 1000 cycles.
