Mineral Spirits

There are four general types of mineral spirits, classified according to boiling point range (BPR):
  • Type I (Stoddard solvent), BPR 149–182 °C
  • Type II (high flash point), BPR 177–196 °C
  • Type III (odorless), BPR 149–196 °C
  • Type IV (low dry point), BPR 149–174 °C

    This standard is manufactured using the Type 1 mineral spirit.

    Note: Cat.#s 31260 and 31261 are produced with CAS# 64475-85-0, a Type 1 Mineral Spirit containing the proper ratio of n-alkanes (higher proportion) and isoparaffins/cycloalkanes (lower proportion). Lots produced prior to March 2017 contained CAS# 8030-30-6, a C10-C13 isoparaffins odorless Mineral Spirit with >98% isoparaffins (branched alkanes/aromatics) and minimal n-alkanes.
