- GENERAL APPLICATION INSTRUCTIONS
Apply POLYSHIELD HT™ SLOW FC 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™ SLOW FC can be sprayedover a broad range of ambient temperatures. It is recommended that POLYSHIELD HT™ SLOW FC be sprayed in multi-directional (north-south/east-west) passes to ensure uniform thickness. The polyol “B” component must be thoroughly power mixed each day, prior to use.
- MIXING & THINNING
- The polyol “B” component must be thoroughly power mixed each day, prior to use. Thinning is not required.
- Using any thinner may adversely affect product performance.

Technical Details & Test Data
- PROCESSING EQUIPMENT & SETTINGS
- 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 HARD CAP™ 100.
- Machines capable of producing a higher dynamic psimay be required depending on the service environment the HARD CAP™ 100 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.
- LIMITATIONS
- POLYSHIELD HT™ SLOW FC is for professional use only.
- User must be proficient in the application of POLYSHIELD HT™ SLOW FC and the use of the high pressure heated plural component equipment used to apply it.
- POLYSHIELD HT™ SLOW FC 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™ SLOW FC 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.

- COLORS
POLYSHIELD HT™ SLOW FC is available in SPI standard colors (Sand, Medium Gray, and Black).
Note: POLYSHIELD HT™ SLOWFC is an aromatic polyurea; therefore, as with all aromaticscolor change and superficial oxidation will occur. Aliphaticurethane and other suitable topcoats can be used wherelong-term color stability and increased longevity in full sunexposure are of critical importance.
- PACKAGING
