Does anyone have any experience or thoughts on the following
chemicals used for air handling HVAC system with water treatment
programs? Are they ok for museums?

    Nalco 2897: an aqueous solution of acrylamide copolymer,
    carboxylate, sodium phosphonate, sodium molybdate, sodium
    hydroxide and a substituted triazole

and

    Nalco 2838: an aqueous solution of glutaraldehyde based
    microbiocide.
