Environmental - Groundwater Protection, Waste- MIXING & THINNING
Thoroughly agitate the “B” components of this product prior to application. Use a SPI folding blade mixer, or equivalent equipment approved by SPI. Install mixer through the extra2” bung hole provided on all “B” drums. Care must be taken not to cross contaminate the individual components with the mixing equipment. Thinning is not required. Using anythinner may adversely affect product performance.
- GENERAL APPLICATION INSTRUCTIONS
Apply POLYSHIELD HT™ TRAFFIC COAT to only clean, dry, sound surfaces free of loose particles or other foreign matter. A primer may be required; subject to type and condition ofthe substrate. POLYSHIELD HT™ TRAFFIC COAT can be sprayedover a broad range of ambient temperatures. It is recommended that POLYSHIELD HT™ TRAFFIC COAT be sprayed in multi-directional (north-south/east-west) passes to ensure uniform thickness.
COMMON SUBSTRATES:
STEEL: 4-5 mil anchor profile is best for maximum adhesion andvaries 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 recommended to prime wood and other porous surfaces before application of heated, fast-set polyureas to reduce pin holing).
CONCRETE: Prepare concrete in accordance with SSPC/NACE Standards and SPI Concrete Prep Guide.
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 POLYSHIELD HT™ SL. Contact SPI for additional information.

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™ TRAFFIC COAT.
- Machines capable of producing a higher dynamic psimay be required depending on the service environment the POLYSHIELD HT™ TRAFFIC COAT 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.
- PARAMETERS & LIMITATIONS
- POLYSHIELD HT™ TRAFFIC COAT is for professional use only. User must be proficient in the application of POLYSHIELD HT™ TRAFFIC COAT and the use of the high pressure heated plural component equipment used to apply it.
- POLYSHIELD HT™ TRAFFIC COAT must be stored at temperatures between 60—90°F (15—32°C).
- Liquid temperature in containers/drums during application 70—100°F (21—38°C).
- Apply POLYSHIELD HT™ TRAFFIC COAT when surface and air temperatures are above 40°F (5°C) and the surface temperature is at least 5°F (3°C) above dew point and rising.
- Avoid moisture contamination in containers. Containers should not be resealed if contamination is suspected.CO2 created pressure can develop. Do not attempt to use contaminated material.
- Undried air exposed to liquid components will reduce physical properties of the cured coating.
Note: The material supplied is a two component system(component “A”/component “B”, which is used to formulatethis product. The quality and characteristics of the finished polymer is determined by the mixture and application of thetwo components by the person applying the polymers.
