Priamine™ is a low-viscous, bio-based* (calculated), dimer diamine product range, which improves flexibility, water barrier properties, and adhesion in a variety of applications, including polyamides, epoxy, polyimides and elastomers.

Priamine™ 1074 dimer diamine is a low viscosity, dimer diamine building block designed for use in polyamides. This building block offers high flexibility, moisture repellency and improved adhesion to plastic.

Nov 30, 2017 · In this work we report the effect of the aromatic dianhydride structure on the thermal, optical, and mechanical properties and relaxation behavior of a set of polyimides based on a biobased aliphatic dimer diamine (DD1).

Jun 24, 2017 · In this work, the effect of the high molecular weight bio-based diamine on the chemical structure and selected properties of poly (ether-urethane-urea)s has been investigated. The ether-urethane prepolymer was cured using 1,4-butanediol and/or bio-based diamine.

The dimer diamines are derivatives of fatty acids obtained from a dimerization process (Diels-Alder reaction). As their corresponding dimer fatty acids, they can be used as building...

Sep 28, 2020 · A series of diamine derivatives of dimerized fatty acids produce by Croda company have been used successfully in the synthesis of NIPUs via the proposed method.

Nov 5, 2021 · The branched-structured dimer diamine efficiently suppressed the crystallinity of the polyamide elastomer system and induced chain entanglement networks for enhancing melt strength.

Sep 15, 2023 · Dimer fatty acids (DFAs) have recently received much attention due to their numerous benefits: being environment-friendly, biodegradable, inexpensive, widely accessible, soluble in hydrocarbons, and low reactivity, and offering an excellent platform for polymeric materials (Petrovic, 2008).

Preparation and Free Radical Cure of Dimner Diamnine Bismaleimide. Approved for public release; distribution unlimited. A new thermally stable polymer is described and methods for syn-thesis and free radical cure of its "monomer" are presented.

Priamine™ 1073 dimer diamine is a low viscous, dimer diamine building block designed for use in polyamides, polyurea and epoxy coatings and adhesives. As a curing agent for epoxy or modifier for polyurea it offers reduced brittleness, enhanced moisture protection and good flow.
