Abstract

The present disclosure is generally directed to solvent mixtures for swelling and bonding polymeric substances for use in facilitating the connection of polymeric substances to other parts. A swelling solvent solution according to the present disclosure may comprise between 5 % and 95 % by volume n-Octane and between 5 % and 95 % by volume of either a heptane isomer (such as n-Heptane) or a nonane isomer (such as n-Nonane). The swelling solvent solution may be used to swell polymeric parts to enable the parts to be attached to other parts. A bonding solvent solution according to the present disclosure may comprise between 2 % and 98 % by volume of at least one of: acetone, MEK, heptane, octane, nonane, isohexane, and THF, and between 2 % and 98 % by volume cyclohexanone. The bonding solvent solution may be used to bond polymeric parts to other parts.
