Re: [BKARTS] Soluble Nylon

Frank, I've never worked with soluble nylon nor seen the problematic results
of its use, but there are a number of negative comments about it at the
following website: palimsest.stanford.edu    Scroll down and do a CoOL search for
the term soluble nylon, if you'd like to read more on it than the excerpt below.

Soluble Nylon Reevaluated

. . .Experience with a large number of objects made of widely differing
materials that were treated with soluble nylon as long ago as the late 1950s and
early 1960s has shown that, without exception, all of them exhibited the same
problems: 1) the film had attracted dirt and dust, badly discoloring the objects
and obscuring painted decoration; 2) the film was not matt; 3) the film had
exerted strong contractile forces, peeling off the surface of the object with
it; 4) the film was no longer flexible; and 5) the film was insoluble. Of the
desirable properties originally claimed for it, permeability to water is the
only one that seems to be maintained over time. . .
