“Introducing the PSX 700 factor 3, PPG’s innovative technology proves that you do not need a three-coat system to obtain the optimum corrosion resistance of a zinc primer and an epoxy mid-coat, along with the long-term gloss and colour retention of conventional aliphatic polyurethane.

Now, with only one coat of zinc primer, plus one coat of our breakthrough PSX 700 you get performance equalling, or surpassing, the finest three-coat systems available today.

Our unique system uses patented engineered siloxane components delivering the excellent adhesion, toughness, corrosion and chemical resistances of epoxy siloxane.

In addition, PSX 700 removes the need to use the traditional mid-coat epoxy to achieve excellent resistance to weathering, exterior gloss and colour retention.

PSX 700 offers unsurpassed benefits in three critical performance areas, the benefits of PSX 700 are more than just a reduction in coats.
