Advantages :
10 to 90 poise at 20°C
Due to the very high α-eleostearic acid content of Chinese wood oil (+/- 80%), the resulting stand oil has excellent reactivity.

Best expresses the characteristics of each stand oil, namely:
Baked oils are exclusively pre-oxidised linseed oils with added cocktails of driers. This oxygen-catalyst combination makes the baked linseed oil more reactive. Depending on the application and the target markets, baked linseed oils can be diluted with petroleum solvents.
The range of baked linseed oil is mainly based on 3 parameters: colour, acid number and drying time :
The main applications are :
Oxidised oils, known as « blown oils », are obtained by incorporating oxygen at moderate temperatures.
Oxidised linseed oil
Applications :
Oxidised soybean oil
Applications :
Oxidised rapeseed oil

This product, from the VEOLISOL range, is the result of our know-how in terms of developing tailor-made products for our customers.
It combines the characteristic performances of several vegetable oils and thus makes it possible to obtain a product which is very easy to use or to apply (because of its solvent power) while having a drying time of only a few hours.
Reactive thinners are very popular in the wood treatment and protection industry.
Made from vegetable oil methyl esters (VOME) such as flax, soya, rapeseed or palm – these esters retain the same fatty acid profile as the original oils but have a viscosity up to ten times lower.
The VEOMUL range is the result of the combination of Vandeputte’s oleochemicals, soap and detergents divisions and the use of new renewable raw materials to replace traditional petro-sourced substances.
The range is available according to performance, field of application and bio-sourced carbon content.
Chinese wood oil or tung oil is obtained by mechanically pressing the dried and crushed nuts of the Aleurites Fordii tree. These nuts contain nearly 50% of a crude oil composed of more than 70% α-eleostearic acid, a fatty acid with 3 conjugated double bonds that makes the oil highly reactive.
Applications :
Advantages :
Castor oil N°1 or FSG (First Special Grade) is obtained from the seeds of Ricinus communis. From these seeds is extracted an oil composed of more than 90% ricinoleic acid characterised by its hydroxyl function (-OH). This function gives it specific properties used in many fields of application.
Applications :
Advantages :
Safflower oil is extracted from the seeds of the dyer’s thistle (Carthamus tinctorius). From these seeds an oil is extracted which consists of more than 70% linoleic acids (CLA) characterised by two conjugated double bonds. This fatty acid gives the oil a very high reactivity.

Advantages :
Refined soybean oil
Crude and refined rapeseed oil
Refined sunflower oil
