TOXICITY CHARACTERISTICS OF CURED FILM OF PROTECTO 401

Cured Films of Protecto 401TM have been independently tested using the Environmental Protection Agency Method 1311 Toxicity Characteristic Leaching Procedure. This procedure is a determination of leachable characteristics of the sample for the following chemicals.

Arsenic

Barium

Cadmium

Chromium

Lead

Mercury

Selenium

Silver

Benzene

Carbon tetrachloride

Chlorobenzene

Chloroform

1,2-Dichloroethane

1,1-Dichloroethane

Methyl ethyl ketone

Tetrachloroethylene

Trichloroethylene

Vinyl Chloride

Toluene

o-Cresol

m & p Cresol

Cresol (o+m+p)

1,4-Dichlorobenzene

2,4-Dinitrotoluene

Hexachlorobenzene

Hexachlorobutadiene

Hexachloroethane

Nitrobenzene

Pentachlorophenol

Pyridine

2,4,5-Trichlorophenol

2,4,6-Trichlorophenol

Fully cured films of Protecto 401TM do not leach any of these chemicals in an amount which exceeds that allowed by EPA Test Method 1311.

Based on the above testing and a literature search, Protecto 401TM, when used to protect sewer lines against corrosion, does not present a health hazard to humans or any risks to the environment.
