- MIXING & THINNING
Thoroughly agitate the “B” components of this product priorto application. Use a SPI folding blade mixer, or equivalent equipment approved by SPI. Install mixer through the extra air specific 2” bung hole provided on all “B” drums. Care must be taken not to cross contaminate the individual components with the mixing equipment; for the best mixing results, supply theSPI mixer with 25 cfm of air at 100 psi. Thinning is not required. Using any thinner may adversely affect product performance.
- GENERAL APPLICATION INSTRUCTIONS
Apply POLYSHIELD HT™ SL only to clean, dry, soundsurfaces free of loose particles or other foreign matter. POLYSHIELD HT™ SL can be sprayed over a broad range ofambient and substrate temperatures. It is recommended that POLYSHIELD HT™ SL be sprayed in multi-directional(north/south-east/west) passes to ensure uniform thickness.
OTHER COMMON SUBSTRATES:
STEEL: 4-5 mil anchor profile is best for maximum adhesion and varies per application and conditions; adhere to proper SSPC standards.
NON-FERROUS METALS: Prepare surface in accordance to SSPC-SP16 (Brush-off Blast Cleaning of Non-Ferrous Metals), It is imparative that the user perform their own adhesion tests.
WOOD: Apply polyurea onto a clean, dry, and sanded surface;free from burrs, splinters and loose debris. (It is recommendedto prime wood and other porous surfaces before application ofheated, fast-set polyureas to reduce pin holing).
CONCRETE: Prepare concrete in accordance with SPI Concrete Prep Guide and SSPC/NACE Standards.
PREVIOUSLY APPLIED COATINGS: SPI recommends UB™(ULTRA BOND™) products over existing coatings that are past the recoat window and/or application over other coatings.The use of SPI Prep Wipe™ solution will tack up the existing polyurea coating and can help promote bonding of the FULLMETAL JACKET™ PLUS. Contact SPI for additional information.
On all above listed substrates and others, please contact SPISales or Technical Support for more information specific toyour application, including industry standards such as SSPC and NACE. Adhesion tests are always recommended priorto application.

Tack Free ± 12 sec. Post Cure*** 24 hours
Recoat 0- 12 hours * All cured film properties are approximate since processing parameters, ad-mixture types, and quantities change physical properties of the cured elastomer. Elevated temperatures will accelerate the curing process and shorten the re-coat window.
** Test performed in a dry, static environment.
*** Complete polymerization to achieve final strength can take up to several days or weeks, depending on a variety of conditions or product type. All samples for above tests were force cured 48 hours or aged for more than three weeks. It is recommended that the user perform their own independent testing.
The samples for tests were sprayed with Graco HXP3 @ 2500 psi dynamic (17 mpa). Primaries/Hose Heat 170°F (77°C,) MP Fusion gun with 29/29 mixing chamber with .040 ceramtip. Test results from SPI.- PARAMETERS & LIMITATIONS

EQUIP & MFGBoss - Standard 1:1 ratio, heated, plural-component equipment developing a minimum of 2000 psi (10.4 MPa) dynamic pressure at the gun with heating capabilities to 170°F(77°C) will adequately spray POLYSHIELD HT™ SL.
- Machines capable of producing a higher dynamic psimay be required depending on the service environment the POLYSHIELD HT™ SL will be exposed to.
- Proportioning machine primary heater temperature 160-170°F (71-77°C).
- Hose temperature 160-170°F (71-76°C). A hose thermometer inserted under the insulation near the gun should read a minimum of 145-155°F (63-68°C).
- Physical properties will be enhanced when sprayed at higher pressure (3000 psi or more); and utilizing an impingement mix gun such as MP Fusion or GX7-DI gun.
- Do not use mixing chambers with output greater than 1.5 gallons per minute.
Packaging & Availability
- Packaging Type
- COLORS
POLYSHIELD HT™ SL is available in SPI standard colors(Sand, Medium Gray, and Black).
Note: POLYSHIELD HT™ SL is an aromaticpolyurea. Therefore, with all aromatics, color changeand superficial oxidation will occur. Aliphatic urethane, polyaspartics, and other suitable topcoats can be usedwhere long-term color stability and increased longevity infull sun exposure are of critical importance.
- PACKAGING
