* This formulation is
just a guide and it includes the main ingredients of pigmented
coatings. The drying time for the formulations prepared using
Mordry 410 remained
constant after 2 months from the preparation while those
prepared using Cobalt
Octoate suffered from sever "loss of dry", which
was reflected on prolonged drying
time. This phenomenon for cobalt driers is believed to be
because of the adsorption of
the metal on the pigment surface and/or coordination of
cobalt carboxylate to form
macro-molecules, thus leading to the loss of drying
efficiency with time.
* In addition to that,
coating films based on Mordry 410 tend to have decreased
yellowing over time (and especially if not exposed to light)
compared to those based
on Cobalt driers.
