THERMO-SHIELD ®  TANK SHIELD

TANK SHIELD

DESCRIPTION
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.

















TYPICAL USES
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.

PRIMER
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.

SURFACE PREPARATION
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.

COLORS
White and any custom color available. Darker colors will give a correspondingly lower
Reflectivity.

V.O.C.
0.33 lbs / gallon
39.5 grams / liter

THEORETICAL COVERAGE (2 to 3 Coats)
7 m² per gallon at 380 microns DFT (75 sf/gallon at 12 mills DFT) with no loss

DRYING TIME
To set: 45 minutes / To re-coat: 12 hours / To through: 12 hours
At 24 Deg C (75 Deg F) and 50% relative humidity
INSULATION
Reflectance 89%, Emittance 94%, Conductance 0.05 W/mK

FLEXIBILITY
Coatings remain flexible at -50 Deg F (-45.6 Deg C). Eliminate thermal-shock damage.
Maintain their strength at 400 Deg F (204.44 Deg C).

ADHESION
Excellent adhesion to steel and a wide variety of substrates: wood, urethane foam,
galvanized steel, aluminum, concrete, asbestos and many others.

SPREADING RATE PER COAT (1 millimeter = 1000 microns)
m²/gallon WFT(microns) DFT(microns)
Suggested 6.7 556 (22 mills) 330 (13 mills)
Maximum 8.7 445 (18 mills) 254 (10 mills)
Minimum 5.8 635 (25 mills) 394 (16 mills)
This rate allows for 10% loss

MIXING
Stir each container thoroughly using low speed mechanical agitation to avoid air
Entrapment.

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.

THINNING
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.

EQUIPMENT
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
adequate protection.
Airless Sprayer: Apply all coats in the same direction. Do not cross spray. Cross spraying
may reveal surface imperfections such as small undulations, etc.
Tip Orifice: .031 inches
Atomizing Pressure: 2200 - 2500 psi
Fan Spread: 60 Degrees
Pump: Minimum 1 gallon per minute at 2500 psi
Filter: Remove filters and screens
Prime pump with water before attempting to spray Thermo-Shield® Tank Shield.
Acceptable equipment includes: Binks Super Hornet, Graco 433 or larger, and many
Others.
CLEAN UP
Clean tools and equipment with warm soapy water. Rinse with clean water; flush mineral
spirits through spray equipment to prevent rusting and to lubricate packing and gaskets.
