Alkyd resin

Alkyd resins are synthetic resins that are made in combination with oil, for example linseed oil or soya bean oil. The oil makes the alkyd resin susceptible to yellowing under the effect of light. As a binder for paint the resin is dissolved in white spirit. Due to the presence of both oil and white spirit the drying is chemical as well as physical. As a result of the evaporation of the white spirit the brushstroke will partly disappear.
