Toxic at eye contact

Have you ever heard of a substance that can kill through eye contact? I
didn't.

Our company is currently developing a waterbased 2-component coating, in
which one of the two component contains "Epilink 700"; an emulsion of an
amino-functional adduct having a high molecular weight. (The other
component contains an epoxy-functional polymer. If both components are
mixed they react, and form a high-performance coating.)

We recently received information from the Epilink-supplier that this
substance is lethal to both rabbits and rats if applied to their eyes, in a
standard eye irritation test, even in a 10% dillution. Animals all die
within the hour, even if eyes are washed out after 1 minut of exposure. The
substance appears not to be toxic through the more general routes of enty
into the body (skin,ingestion,inhalation), and is not even classified as a
skin irritant.

What could be the mechanism? Are there any substances with similar
behaviour? Would it be lethal to humans? Is someone doing research on this
allready?

Kind regards,
