Description

Polyamid-2,2 (Molekulargewicht 700 - 800 G/Mol) is a specific, low molecular weight polyamide resin, also known as a dimer acid-based polyamide, with the CAS registry number 34872-59-8. This material is valued for its excellent adhesion, flexibility, and chemical resistance, making it a crucial component in high-performance formulations. It is primarily sought by manufacturers in the coatings, adhesives, and ink industries seeking to enhance the durability and functional properties of their products.

Application

• Reactive Modifier for Epoxy Resins: Used as a flexibilizer and toughening agent in epoxy coatings, adhesives, and composites.
• Corrosion-Resistant Coatings: A key binder in high-performance industrial and marine protective coatings.
• Hot-Melt Adhesives: Provides strong bonding, thermal stability, and water resistance in packaging and assembly applications.
• Printing Inks: Imparts gloss, adhesion, and rub resistance to inks for flexible packaging and overprint varnishes.
• Can and Coil Coatings: Enhances formability and chemical resistance in metal decorating and protection.
• Sealants and Caulks: Acts as a non-reactive plasticizer and adhesion promoter.

Quality Control

Our Polyamid-2,2 is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure consistent properties such as amine value, viscosity, and molecular weight distribution. A Certificate of Analysis (COA) documenting these parameters is provided with each shipment to guarantee compliance with your technical requirements.

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 performance.
