PSX® Polysiloxane Technology

PSX 700 used as a hangar floor finish coat system by KTM Coatings, San Diego, CA

PSX 700 is a special epoxy siloxane coating that is self-priming or can be used with a suitable primer. It offers a combination of outstanding corrosion resistance, abrasion resistancem and unparalleled long-term gloss and color retention in one product. Whether applied to structural steel, concrete floors or non-ferrous substrates, PSX 700 delivers longterm performance.

Why PSX provides you longer lifecycle service and cuts your coating costs...

  1. The Si-O bond is very stable and resistant to attack by atmospheric oxygen even at very high temperatures. Organic polymers will oxidize and degrade under these conditions.
  2. The Si-O bond is unaffected by Ultraviolet radiation resulting in excellent weatherability exceeding any organic polymer.
  3. Siloxanes have very low viscosities so they can be formulated to very high solids and low VOCs.
  4. Siloxanes are hydrophobic, do not require isocyanates for curing, and have excellent compatibility with inorganic substrates.

PSX 700 Less than 100 grams per Liter VOC Product Data Sheet & Application Instructions

PSX 700 is available in a broad ranging palette of colors from whites to pastels to deep colors of bright reds, yellows, oranges and deep blues and greens. In the PSX product line deep colors are referred to as "Group 3" colors due to their strength and resistance to ultra-violet damage. Safety colors such as "Safety Yellow" and "Safety Red" are Deep Colors.

We recommend you consider purchasing Amercoat 911 thinner or PPG 97-739 which are blended to improve the application of PSX 700 in varying environmental conditions. Most of our customers purchase Amercoat 911 thinner outside of California and PPG 97-739 VOC exempt thinner for applications in VOC regulated California so they can thin the PSX 700 up to 10%.
