Is this for the same thing? CF929/CF246 are lower end products whilst it seems they are using (at keast in some portion) BYK 024/018 which are a completely differnt chemistry (and a lot more costly). How is your contact at TOA - we shouldn't just throw samples at them without an idea of what they are looking for. Do you know all the defoamers they use or if not can you find out alongside the volumes?
