Manganesed Phospholene #7

I am examining and treating a group of archaeological metals treated
in the 1960's with the rust remover and corrosion inhibitor
Manganesed Phospholene #7 (Western Reserve Laboratories, Cleveland
OH), a proprietary product that saw some use in the past and is
still manufactured and used today. Some of the artifacts in the
group have remained stable, however others are corroding. With the
awareness that there are many factors at work such as surface
coatings, changing environmental conditions, etc., it would still be
helpful to know more about the mechanisms of this product to better
understand its effects. Has anyone researched or used this product,
or encountered collections on which it was used?
