Description

Fatty Acids/Sebacic-Stearic Acid/Ethylenediamine Polyamide is a polyamide resin derived from the condensation of ethylenediamine with a blend of sebacic and stearic acids. This specialized polymer offers a unique balance of flexibility, chemical resistance, and adhesion properties, making it a valuable component in high-performance formulations. It is primarily sought by manufacturers in the coatings, adhesives, and ink industries for its role as a versatile rheology modifier and binder.

Application

• As a thixotropic agent and rheology modifier in solvent-based industrial and protective coatings.
• Key component in the formulation of high-strength, flexible hot-melt and reactive adhesives.
• Used as a binder and grinding resin to improve pigment wetting and dispersion in printing inks and specialty paints.
• Employed in the production of corrosion-resistant primers and anti-corrosive coatings for metal substrates.
• Serves as a flexibilizing agent and curing component in epoxy-based systems and composite materials.
• Acts as a processing aid and compatibilizer in select polymer compounds and elastomeric formulations.

Quality Control

Our Fatty Acids/Sebacic-Stearic Acid/Ethylenediamine Polyamide is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assessment of amine value, viscosity, and softening point. Certificates of Analysis (COA) documenting full specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product properties.
