Description

General description

Dimer acid, hydrogenated is a fatty acid with 36 carbon atoms. It consists of a cyclohexene ring which can be synthesized by clay-catalyzed dimerization at 230-250°C.

Improves flexibility, toughness, impact resistance, dyeability and hydrolytic stability of polymers.

Application

Comonomer in polyesters, polyamides and polyurethanes.

Dimer acid, hydrogenated can be used as a corrosion inhibitor for the protection of lead metal substrates. It can also be used in polyamide based hot melting adhesives as a thermoplastic polymer for electronic boards, textiles and packaging systems.

Packaging

250 mL

1 L in poly bottle
