ARC S7 is a low VOC, epoxy novolac vinyl ester based coating intended for high temperature exposures in chemically aggressive applications where the risk for thermal cycling may be present. It is highly resistant to a wide range of inorganic as well as organic acids and hydrocarbon based chemical compounds. The product utilizes a unique reinforcement design allowing it to be highly resistant to thermal cycling exposures up to 180°C (355°F) while maintaining its adhesion and resisting cracking, delamination and permeation.

ARC S7 is able to be spray applied via conventional airless spray systems at a wet film thickness of 0,25 - 0,5 mm (10 - 20 mils) per coat. ARC S7 may also be applied by brush and roller, though with reduced film build. It is recommended to be applied in two coats for elimination of holidays and pinholes.

Composition - Polymer/Nano Particle Composite
Matrix - An epoxy novolac vinyl ester resin reacted with a cumene hydrogen peroxide catalyst.

Reinforcement - A proprietary blend of nano-silicone particles for thermal cycling resistance, coupled with a high density reinforcement package for ultimate resistance to immersion exposures where "cold wall" permeation and chemical resistance is required.

Packaging
Material is comprised of two containers of Part A (14 liters each) and one 500 ml bottle of catalyst.

Chemical Resistance
Recommended for aggressive exposures in a wide range of acid, alkali and hydrocarbon based exposures. Please refer to ARC Technical Services for chemical resistance.

Suggested Uses

  • Flue gas ducts
  • Quench zones
  • Process tanks
  • Storage tanks
  • Steel structures
  • Bag filters
  • Reactor domes

Benefits

  • Resistant to thermal cycling.
  • Resistant to cold wall induced blistering.
  • ARC S7 is well suited for aggressive chemical exposures at elevated exposures and is easily sprayed with conventional spray equipment.
  • ARC S7 does not require a primer and is capable of in-situ curing.
