LINSEED STANDOIL
The polymerisation of refined linseedoil at high temperatures under vacuum results in linseed standoils of various viscosities.
Linseed standoils have excellent pigment wetting and dispersing capabilities and they are a preferred and very effective intermediate between modern short to medium long resins and different types of pigments.
Because of the combination of their bodied aspect and their drying capacities, they are a functional ingredient in various coatings related
products:
●
Linseed standoils find general use in traditional wood and floor sealing
varnishes, in enamels and in house paints to improve the flow, gloss and
durability
●
Lower viscosity standoils can partially replace refined oils as starting
material in the production of alkyd resins and varnishes to reduce the process
time
●
Higher viscosity standoils can be used as sole binder in flat paints and
primers, and can be used as an addititive in heatset printing inks to improve
the drying and adhesion
●
High acidity standoils are often used in the production of calcicoaters
(or limed oils) which are especially useful in primers and flat and semigloss
paints where the non-penetrating character of the Ca-soaps is important in
maintaining the pigment/binder ratio in the film at a similar level to that of
the applied paint, even on a surface of variable porosity
