Frequently Asked Questions
What is another name for linseed oil?
Linseed oil (CAS 8001-26-1) is also known as flaxseed oil, since it is pressed from flax seed. In industrial coatings contexts the unrefined material is commonly sold as raw linseed oil, distinct from boiled linseed oil that has been treated with driers.
What is linseed oil used for?
Linseed oil is a polyunsaturated drying oil used as a binder in oil paints, varnishes, and printing inks, as a penetrating wood finish and preservative, as the base for glazing putty and caulks, and as a feedstock (oxidized) for linoleum flooring.
What are the disadvantages of using linseed oil on wood?
As an air-oxidation drying oil it cures slowly, can take days to weeks to fully harden, and may darken or yellow over time. It also offers limited resistance compared with film-forming finishes and requires reapplication. Note that rags soaked in linseed oil can self-heat during oxidation; consult the SDS for handling guidance.
What is the difference between raw and boiled linseed oil?
Raw linseed oil is the unmodified pressed oil that cures purely by slow air oxidation. Boiled linseed oil has metallic drier additives that greatly accelerate curing; despite the name it is not necessarily heated. Specify which form you require when ordering.
Does RawSource supply linseed oil in bulk, and at what price?
RawSource distributes linseed oil in bulk drums, totes, and larger volumes. Pricing depends on grade (raw vs. boiled), refinement, and order size, so we quote per requirement; request a bulk quote with your target volume and form for current pricing.
