Product Name: GREAT STUFF(TM) Gaps & Cracks Insulating
Foam Sealant 12oz HC ES

Page 8 of 13
Data for Component: Paraffin waxes and Hydrocarbon waxes, chlorinated
Movement & Partitioning
Expected to be relatively immobile in soil (Koc > 5000). Given its very low Henry's constant,
volatilization from natural bodies of water or moist soil is not expected to be an important fate
process.
Henry's Law Constant (H): < 1.0E-07 atm*m3/mole; 25 °C Estimated
Partition coefficient, n-octanol/water (log Pow): > 6 Estimated
Persistence and Degradability
Expected to degrade only slowly in the environment.
Data for Component: Isobutane
Movement & Partitioning
Bioconcentration potential is low (BCF less than 100 or log Pow less than 3). Potential for
mobility in soil is very high (Koc between 0 and 50).
Henry's Law Constant (H): 1.19E+00 atm*m3/mole; 25 °C Measured
Partition coefficient, n-octanol/water (log Pow): 2.76 Measured
Partition coefficient, soil organic carbon/water (Koc): 35 Estimated

Biodegradation may occur under aerobic conditions (in the presence of oxygen).
Indirect Photodegradation with OH Radicals
Rate Constant Atmospheric Half-life Method
2.44E-12 cm3/s 4.4 d Estimated
Theoretical Oxygen Demand: 3.58 mg/mg
Data for Component: Isocyanic acid, polymethylenepolyphenylene ester, polymer with
.alpha.,.alpha.',.alpha.''-1,2,3-propanetriyltris[.omega.-hydroxypoly
Movement & Partitioning
In the aquatic and terrestrial environment, movement is expected to be limited by its reaction
with water forming predominantly insoluble polyureas.
Persistence and Degradability
In the aquatic and terrestrial environment, material reacts with water forming predominantly
insoluble polyureas which appear to be stable. In the atmospheric environment, material is
expected to have a short tropospheric half-life, based on calculations and by analogy with
related diisocyanates.
