Spectragel Medium is a clear thixotropic alkyd medium designed to mix with oil colours, retaining the body of the paint.
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.
Matt Spectragel has a matt finish.
It is a clear medium based on a synthetic resin that accelerates drying of oil colours and improves their weather resistance.
Ideal for glazing and extending colours while retaining gloss and structure of paint.
