Certification

Product certified for Low chemical emissions UlCOM/GC Ul 2818.

Storage Stability
Part A
One year at 65°F to 90°F
Part B
Six Months at 65°F to 90°F
Packaged Product Data

Part B contains polymeric diisocyanate. High concentrations can occur in inadequately ventilated environments when this is sprayed, aerosolized or heated. In such cases, respiratory protection must be worn.; The coating will set in 30 seconds when applied to an insulated surface. A complete cure can take several hours depending on the ambient temperature.; Spray equipment may be cleaned with T-5112 thinner.

Regulatory Compliance

GacoFlex U-8782 meets LEED Solar Reflectance Index (SRI) requirements and qualifies for LEED certification points under the Sustainable Sites Category, Credit 7.2: Reduction of Heat Island Effect. U-8782 Ivory also meets the 3 year aged testing requirements for the California Energy Commission, Energy Efficiency Standards for Residential and Nonresidential Buildings Title 24, for Solar Reflectance and Thermal Emittance.
