    Ok so not the same chemical. That is good news.
    Our fountain solution has 1 OCTYL-2-PYRROIDONE Cas#2687-94-7 at less than 2%

    Even if a fountain solution did have pyrroidone in it at a very low % , once the fount is mixed with water at its correct % the actual amount of pyrroidone in the system/press would be very minimal.

    Although if it is in roller washes that could be cause of concern

    Al there will not be any responses to this. It is a catch 22 for both the wash supplier and the roller manufacturer. Since they both already know what it does they cannot comment.
    Now lets look at it in a different way maybe they honestly don't know. If this is the case then they are ignorant of their product and cannot recommend a wash and roller compound that is compatible. Either way the printer ends up paying for wash that can eat up his rollers or buy rollers that will be eaten up by the wash.

    Lukew is this a Fogra approved fountain solution?

    Octyl or Methyl they are equally nasty and both exhibit the same reproductive troubles.

    I have not been told if it is fogra approved but I think highly likely not. They do state though that "all products are formulated to meet or exceed all European Approval agencies AND all current press manufacturers specifications."

    Lukew these links
    Regulatory agencies and compliance requirements - Elo TouchSystems - Tyco Electronics http://europa.eu/legislation_summari.../l21282_en.htm

    will assist you with researching the European Approval Agencies.
    As for the current press manufacturers specifications I would ask for the list of manufacturers and their specifications. It is good procedure to double check on specifications. Some press manufacutrers require that chemistry is within spec for warranty issues.

    Where can you find the current press manufacturers specifications for chemistry?

    Contacting each press manufacturer one by one with that question seems like a logical place to start.

    When will the suppliers ever stop playing games. Many times I am ashamed to even be associated with this industry. Just about when you see hope for cleaner chemistry another item appears. There are a few bright spots in chemical suppliers and when i say a few I mean 2.

    There are just way way too many associations and groups that worry about their own well being and ability to collect fees and member dues. This covers all aspects from green power, forrest management, carbon offsets, consumables, green labeling and the list is almost endless. Now some of these groups are worth their salt but they also are far and few between.
    We are all human beings and if a governing body or regulatory group banded or severely limited the use of a chemical wouldn't it behove us to think that this would be beneficial to all mankind and not just the particular local or country where the restrictions are enforced.

    What do you think can be done to unify many of these certifying entities into a central body that can have meaning and recognition world wide.
