Dave,
There's no practical way to make any NC-based glue "non-shrinking". The solvent is a LARGE portion of the package, and it occupies volume. When the solvent evaporates, that volume is reduce.

It's a sort-of 'rule of life' that solvent-based adhesives (even water-based, like "while glue") shrink as they dry.

ok, I'm not gonna worry about the "non" shrinking side of things, probably not critical for what I have in mind
