DMSO can be used as a polymer solvent in selected PAN processes and as a solvent in selected electronics-cleaning systems. The molecule is the same, but its role and acceptance criteria differ.
PAN processing
For PAN spinning, begin with polymer dissolution, dope behavior and the exchange between solvent and coagulation bath. Read DMSO in PAN Spinning Solutions for the full discussion.
Electronics cleaning
For photoresist removal, begin with the resist, exposed materials and complete cleaning formulation. Read DMSO in Photoresist-Removal Formulations for the full discussion.
An application name or grade label does not replace the analytical and process requirements established for the selected use.
