I know nothing about that, but I looked up the ingreditents...following are some of what it says...I personally would not use this stuff based on what I read about it.

HARDENER:
Toxicity: Skin and eye irritant. Possible respiratory irritant. The aminophenol can cause severe irritation and may be corrosive on prolonged contact. It may be a sensitizer. It can also be corrosive to eye tissue leading to permanent injury including blindness. It may irritate the respiratory tract and may cause delayed lung damage upon overexposure to fumes or vapors. It can also cause fatigue, muscular weakness, labored breathing, or gastrointestinal irritation
if swallowed. The relatively low concentration of the aminophenol in the product may minimize some or all of these effects.
