1. A dialkyl tin oxide composition comprising:
about 85% by weight of dibutyl tin oxide, wherein the dibutyl tin oxide has a particle-average diameter of about 300 microns, as measured before being added to the dialkyl tin oxide composition; and
about 15% by weight of a mixture that is
about half by weight methyl acrylate; and
about half by weight dimethylaminoethanol;
the percentages by weight of dibutyl tin oxide and mixture being relative to the weight of the dialkyl tin oxide composition.
