ARC S4+ Datasheet

Source: A.W. Chesterton Company

An advanced polymer composite formulated to protect equipment from extreme chemical attack and corrosion. It is typically applied by spray, roller or brush at a nominal thickness of 375 microns (15 mils) per coat in a 2 coat system. Non-shrinking, 100% solids. Colors are Gray and Red.

ARC S4+ is an advanced multi-functional composite lining system formulated for ambient and elevated temperature service. It is designed to be spray applied but may also be applied by roller or brush. ARC S4+ yields excellent barrier properties for long-term corrosion and chemical resistance in immersion exposures when used in a multicoat application. Cured ARC S4+ provides a high gloss surface with unrivaled adhesion and corrosion protection.

Composition - Polymer/Surface Modified
Mineral Composite
Matrix - A two component, multi-functional, modified epoxy resin, reacted with a modified cycloaliphatic amine curing agent.

Reinforcement - A proprietary blend of surface modified mineral reinforcements designed to provide resistance to permeation, chemical attack and corrosion.

Packaging Material is available in two sizes: 4 and 16 liter kits. Each package contains two pre-measured containers (Part A and Part B). A mixing tool, brush and instructions for use are enclosed with the 4 liter kit. The 16 liter kit contains only application instructions.

Based on a 375 microns (15 mils) thickness in a single coat:

4 liters will cover 10.7 sq. meters (113 sq. ft.)
16 liters will cover 42.7 sq. meters (452 sq. ft.)

Chemical Resistance
Recommended for exposure to a wide variety of concentrated chemicals such as hydrochloric acid, phosphoric acid, sulfuric acid, potassium hydroxide, and sodium hydroxide and other chemicals. Please refer to the ARC Chemical Resistance Charts for a comprehensive list of chemicals and associated exposure ratings at ambient temperature. Post curing will improve chemical resistance; contact ARC Technical Services for elevated temperature exposure.
