This is the "replacement" for the widely used ERL 4206, a component of the
widely used SPI-Chem™ Ultra-Low
Viscosity Kit but which is no longer produced and to our knowledge is
not available anywhere in the world (so far as we know). If you should be
aware of an actual manufacturer of the equivalent to ERL 4206, we would be
greatly appreciative of knowing who is doing such manufacturing. However,
our testing of ERL 4221, as a plug-in replacement for ERL 4206 would
indicate that on a blind test, most users could not tell a difference
so long as the recipe is suitably altered to account for differences in
properties that do exist. For example, for the use of ERL 4221 as part
of a Spurr formulation low viscosity kit, see the
Spurr formulation low viscosity kit Use Instructions.
