Description
VM&P naphtha, pure grade. The product is a defined-boiling-range aliphatic hydrocarbon cut rather than a single compound, which is why the SDS records no single CAS number for the finished product. The synonym given is varnish maker and painters naphtha and the identified use is as a solvent.

- Octane – CAS 111-65-9 – 5-10%
- Heptane – CAS 142-82-5 – 5-10%

Frequently asked questions
Is VM&P naphtha a single compound?+
No. It is a defined-boiling-range petroleum distillate cut, so the SDS records no single CAS number for the finished product. The declared components are hydrotreated light naphtha / light aliphatic solvent naphtha (CAS 64742-49-0, 68410-97-9, 64742-89-8) at 90-100%, plus octane (CAS 111-65-9) and heptane (CAS 142-82-5) at 5-10% each.
What is the boiling range and evaporation rate?+
The SDS gives a boiling range of 118-150 °C (244-302 °F), a melting point below -60 °C, and an evaporation rate below 1 relative to butyl acetate. Kinematic viscosity is below 0.01 mm2/s at 40 °C.
What is the density?+
0.7601 g/cm3 at 15.6 °C (60.1 °F) per the SDS. Vapour density is above 4 at 20-25 °C, so vapour will accumulate in low or confined spaces.
What are the flammability data and handling requirements?+
Flammable Liquid Category 2, with explosive limits of 0.9 vol% lower and 7.6 vol% upper and autoignition between 246 °C and 470 °C. The SDS calls for containers to be grounded and bonded, non-sparking tools, explosion-proof electrical, ventilating and lighting equipment, and notes that vapours may form an explosive mixture with air.
What health hazards are declared?+
Flammable Liquids Category 2, Skin Irritation Category 2, Reproductive Toxicity Category 2, single-exposure STOT Category 3 targeting the central nervous system, and Aspiration Hazard Category 1 - the SDS states it may be fatal if swallowed and enters airways. Signal word Danger.
What container sizes are available?+
500 mL, 1 litre, 4 litres, 1 gallon, 5 gallons and 55 gallons.
