TANK SHIELD
DESCRIPTION
Thermo-Shield® Tank Shield is a highly efficient, energy-saving, flexible coatings, 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 resist 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 to shine when coated with Thermo-Shield® Clear Coat.
TYPICAL USES
For the exterior of steel petrol storage tanks and pipelines where reduction of surface temperature is desired. Exterior of steel or polymer water tanks or grain storage silos. 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 coating. Rust should be controlled with the use of rust inhibitors.
COLOR
Tinting may be achieved with Thermo-Shield® Tank Shield by the addition of universal colorants. Darker colors will give a correspondingly lower reflectivity.
PERCEN NON-VOLATILE
51.67% by volume
51.14% by weight
THEORETICAL COVERAGE
7 sm per gallon at 300 microns DFT (75 sf/gl at 12 mils DFT) with no loss (To be applied in 2 to 3 coats)
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 82% Emittance 94% Endothermic Effect® Conductance 0.05 W/mK
FLEXIBILITY
Coating maintains its properties at -50 Deg F (-45.6 Deg C) - Eliminates thermal-shock damage - Maintains its strength at 400 Deg F (204.44 Deg C).
ADHESION
Excellent adhesion to steel and other substrates such as galvanized steel, aluminum, concrete, wood, urethane foam, asbestos and others.
SPREADING RATE PER COAT (1 millimeter = 1000 microns)
Suggested 6.7sm/gl - 556 microns WFT (22 mills) - 330 microns DFT (13 mills)
Maximum 8.7sm/gl - 445 microns WFT (18 mills) - 254 microns DFT (10 mills)
Minimum 5.8sm/gl - 635 microns WFT (25 mills) - 394 microns DFT (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 300 microns) will give the best long-term protection at minimum cost.
THINNING
None required. Clean water in small amounts of up to 0.24 Liter per gallon (1/2 pint) may be added to replace evaporation losses or to adjust for spray equipment configuration. Caution: excessive thinning will cause the coating to loose adhesion and elasticity.
EQUIPMENT
Roller or airless spray application is recommended. Very small areas may be brushed. When Tank Shield is applied by brush, three (3) coats are required for adequate protection. Airless Spray: 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: 1 gallon per minute at 2500 psi. Filter: Remove filters and screens. Prime pump with water before attempting to spray 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.
PACKAGING
One and five-gallon pails. Lined 55-gallon drums.
