TUFCHEM® SILICATE GUNITE

DESCRIPTION

TUFCHEM Silicate Gunite is an inorganic, two component, 100% potassium silicate bonded gunite applied

lining. Properly installed, TUFCHEM Silicate Gunite yields a strong, dense, acid-resistant lining which protects

concrete and steel substrates from most oils, solvents, and a wide range or corrosive acids. It is not resistant

to acid fluorides, hydrofluoric acid, or alkaline environments.

TUFCHEM Silicate Gunite is usually installed with an anchoring system. Consult Corrosion Engineering

specification CES-329 for complete anchor details, and specification CES-336 for complete

installation details.

AREAS OF USE

TUFCHEM Silicate Gunite can be used as a monolithic lining for new equipment or as a maintenance material

for patching and restoring existing linings. It is recommended for use in acidic environments found in

chimneys, breeching ducts, stacks, process vessels, sulfuric acid towers, pollution control equipment, and

corrosive ash hopper linings.

OUTSTANDING FEATURES

100% potassium silicate-bonded, free of any hydraulic cements, thus providing resistance to sulfationhydration reactions.

Non-exothermic chemical setting and curing allows installation of thick sections.

Easy of use – low rebound.

An acid-resistant gunite utilizing liquid silicate binder allows greater tolerance than single component

compositions to which water alone is added, thus providing greater versatility in placement. Outstanding resistance to most acids including sulfuric, hydrochloric, and nitric.

Provides high strength with good abrasion resistance. Where necessary, it may be applied over chemical-resistant membranes, such as

PENNCOAT7 101 System, TUFCHEM® II Membrane, and PACMASTIC® 325 Coating.
