Description

Fatty acids,C18-unsatd.,dimers,polymers with polyalkylenepolyamines and tall-oil fatty acids,reaction products with bisphenol A-epichlorohydrin polymer and diethylenetriamine is a high-performance polymeric resin derived from modified fatty acids and epoxy-amine chemistry. This specialized compound is engineered to provide exceptional adhesion, flexibility, and chemical resistance, making it a critical component in demanding industrial formulations. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance the durability and performance of their products.

Application

• Epoxy Curing Agent & Modifier: Acts as a reactive flexibilizer and toughening agent in epoxy resin systems for coatings and composites.
• Industrial & Marine Coatings: Imparts superior corrosion resistance, adhesion to difficult substrates, and hydrolytic stability in protective coatings.
• High-Performance Adhesives: Used in structural and assembly adhesives requiring strong bonding under thermal and mechanical stress.
• Sealants and Caulks: Provides long-term elasticity, weather resistance, and adhesion in construction and automotive sealants.
• Composite Materials: Serves as a matrix resin or modifier in fiber-reinforced plastics (FRP) to improve impact resistance.
• Electrical Encapsulation: Employed in potting and encapsulation compounds for electronic components due to its insulating and protective properties.

Quality Control

Our production of this advanced polyamide-epoxy adduct follows a strict quality management system. Each batch is characterized for critical parameters including amine value, viscosity, and epoxy equivalent weight to ensure consistent performance as a curing agent or modifier. Certificates of Analysis (COA) documenting these specifications are provided with every shipment to guarantee compliance with your formulation requirements and support your own 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). Keep container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect reactivity and performance.
