Ethylene carbonate (EC), 2,4-pentanedione, ethyl 3-ethoxypropionate (EEP), dibutyltin diacetate (DBTDAc), tin(II) 2-ethylhexanoate, methylene iodide (MI), benzyltrimethylammonium hydroxide (40% solution in methanol), methyl isobutyl ketone (MIBK), and HPLC grade water were purchased from Aldrich.
To all formulations, 10% by solids 2,4-pentanedione was added as a pot life extender.
Formaldehyde was measured continuously, using the automated Dasgupta-diffusion-tube sampler to obtain aqueous formaldehyde, which is then mixed with buffered 2,4-pentanedione and measured with fluorescence (Dasgupta et al, 1988).
The concentration of CoNap, Trigonox and 2,4-Pentanedione was systematically varied.
Catalyst savings: Formulations are simpler because no 2,4-pentanedione retarder is needed, and amine accelerators can be eliminated, except perhaps in very thin layers or in cold weather.
