Thermo-Shield® Tank Shield is a highly efficient, energy-saving, flexible coating, designed
to protect and lower the external surface temperature of storage vessels. It is non-toxic and
friendly to the environment. It is completely washable and resists many harsh chemicals
and dirt pick-up. This water-based coating is made from an acrylic resin system filled with
vacuumed ceramic micro spheres that acts as a thermally efficient blanket. Thermo-
Shield® Tank Shield has superb fire resistance - it is grade Class A by UL Standards. It can
be obtained in a variety of architectural colors for signs and logo making. It leaves a
beautiful matt finish but can be made glossy when coated with Thermo-Shield® Clear Coat.
For the exterior of steel petroleum storage tanks and pipelines where the reduction of
surface temperature is desired. Used also for the exterior of steel or polymer water tanks,
grain storage silos and the exterior of most chemical storage tanks. This coating is
resistant to 26 different harsh chemicals including 20% hydrochloric and 25% sulfuric acids.
Use alkyd or epoxy quality primers where required and/or rust inhibitors to make sure rust
will not be present during the application of the coating.
All surfaces must be clean and free from rust, dust, dirt, oil or grease. Minimally, surfaces
must be cleaned to remove any loose or chipped paint or any other foreign material prior to
the application of Tank Shield. Rust should be controlled with the use of rust inhibitors.

NUMBER OF COATS
Two to three coat application (minimum dry film-build of 380 microns with a minimum of 300
microns at any location) will give the best long term protection at minimum cost.
None required. Clean water in small amounts of up to 0.24 Liter (1 cup) per gallon may be
added to replace evaporation losses or to adjust for spray equipment configuration.
Caution: excessive thinning will cause the coating to lose adhesion and elasticity.
Roller or airless spray application is recommended. Very small areas may be brushed.
When Thermo-Shield® Tank Shield is applied by brush, three (3) coats are required for
Airless Sprayer: Apply all coats in the same direction. Do not cross spray. Cross spraying
may reveal surface imperfections such as small undulations, etc.
