General description

Linseed oil is a natural triglyceride and a well known drying oil. Drying of the triglyceride mainly leads to the oxidation of the unsaturated fatty acid segments and polymerization. Oxidative degradation studies of linseed oil show hardening and oxidation of alkylic sections followed by partial fragmentation of the triglyceride structure.[1]

Application

Linseed oil filled urea–formaldehyde resin microcapsules may be used to fix cracks in paints/coatings.[2][3][4] This linseed oil is processed to create a product that is more suited for many uses (such as paint, to name one), in terms of ″drying time.″
