Refined aliphatic distillate of petroleum.

Product Application

Flashpoint

75oC (167oF)

Permissible Exposure Level

300 parts per million parts.

To be used as a diluent when used in small quantities with oil colours.

Langridge Solvent 75 may be added to oil colours, drying oils and oil mediums in small quantities, used to clean dried paint films and  to clean brushes and painting equipment.

Solvent 75 can be added to artists’ drying oils to add extra fluidity. Extreme care should be taken, however, in diluting purely with solvent as its over-use, like all artist’s solvents, can easily underbind paint and lead to a dull, dry lifeless film with potential for dusting or flaking off.

Artists wishing to create very fluid working qualities should refer to painting mediums constructed for that purpose.

Solvent 75 has a low solvent action (KB value) making it a highly useful for gentle removal of surface dirt from paint films (Langridge does not recommend thorough cleaning, including varnish removal, of artworks except by a trained conservator.).

Because of its construction, Langridge Solvent 75 cannot be used for the home manufacture of artists’ varnishes (natural or synthetic). Damar resin cannot be dissolved in Langridge Solvent 75 or any petroleum distillate.

For cleaning brushes Langridge recommends the use of brush cleaning units or containers which have an airtight lid.

Reducing exposure to solvent fumes is to advised at all times as well as preventing evaporation of solvent in the container.

Additional Product Information

A Low Toxic Alternative

Because Langridge Solvent 75 has a Permissible Exposure Level (PEL) of 300 parts per million parts of air, far higher than other 

artist’s solvents, opportunity to exposure of harmful fumes, in comparison to traditional solvents, are dramatically reduced.

Associated issues with prolonged contact with traditional artists’ solvents such as dermatitis, skin and respiratory organ irritation, headaches, etc. can be dramatically reduced or removed by the use of Langridge Solvent 75.

Langridge still recommends the use of good studio ventilation (e.g. open windows) to increase airflow with preferably a properly installed exhaust system.

Travelling with Solvent 75

Because Langridge Solvent 75 has a Flash Point of 75oC (167oF) it is deemed as NON-Dangerous Goods and may be transported by air, road and rail transport as set out by regulations of the International Air Transport Association (IATA).

Using solvents to matte paint 

Artists wishing to have a painting with a matte reflective quality should use a matte medium added to their paints or apply a matte picture varnish once the painting is finished.

The use of solvents to matte paint is not recommended because the matte effect seen is due to the partial destruction of the paint film, leaving an unstable, underbound paint surface liable to crack or dust/flake.

Working Properties

Appearance

Langridge Solvent 75 is a clear and transparent liquid with no odour.

Clean Up

For further washing apply a small quantity of Marseille or other pure olive oil soap and massage the bristles of the brush to release any remaining Solvent 75. Wash thoroughly in warm water. Leave to fully dry before using for oil colours.

Evaporation Times

10ml in 55mm wide open cup at 20o centigrade ambient temperature full evaporation after 3 hours.

Any airflow over the surface will evaporate the solvent more rapidly.
