Spectraflow Medium is a free flowing, slightly thixotropic alkyd medium designed to mix with oil colours. The word thixotropic means sometimes fluid and sometimes gel - this medium becomes fluid when stirred and returns to a gel state when allowed to stand.
Quick drying and will not increase gloss when added to oil colours.
Its liquid state makes it particularly suitable for fine details or large thin areas.
It is a clear medium based on a synthetic resin that dries to a weather resitant and strong, resilient surface.
Available in 250ml, 1L and 2.5L tins.
