Product Description

Dimer acids, or dimerized fatty acids, are dicarboxylic acids prepared by dimerizing unsaturated fatty acids obtained from tall oil, usually on clay catalysts. Dimer acids are used primarily for synthesis of polyamide resins and polyamide hot melt adhesives. They are also used in alkyd resins, adhesives, surfactants, as fuel oil additives, lubricants, etc.
It is a light yellow or yellow viscous transparent liquid and non-toxic.

Dimer acid usually contains predominantly a dimer of stearic ac
