Description

Fatty Acids, C18-Unsatd., Dimers, Reaction Products With Bisphenol A-Bisphenol A Diglycidyl Ether Polymer And Polyethylenepolyamines is a high-performance polymeric amine adduct derived from dimerized unsaturated fatty acids and epoxy resins. This specialized chemical serves as a versatile curing agent and property modifier, offering enhanced flexibility, adhesion, and chemical resistance to polymer systems. It is primarily utilized by formulators in the coatings, adhesives, sealants, and composites industries seeking to improve the durability and performance characteristics of their epoxy-based products.

Application

• Epoxy Curing Agent & Modifier: Acts as a reactive polyamide-type hardener for epoxy resins, imparting improved impact resistance and flexibility to cured networks.
• Industrial & Protective Coatings: Used in high-performance coatings for marine, industrial maintenance, and floor applications where toughness and corrosion resistance are critical.
• Adhesives & Sealants: Serves as a key component in structural adhesives and elastic sealants, enhancing bond strength and substrate wetting.
• Composite Materials: Employed in the production of fiber-reinforced plastics (FRP) and laminates to modify matrix properties and reduce brittleness.
• Electrical Encapsulation: Utilized in potting and encapsulation compounds for electronic components, providing excellent moisture resistance and mechanical protection.
• Construction Chemicals: Incorporated into grouts, mortars, and concrete modifiers to improve durability and chemical resistance.

Quality Control

Our production of this polymeric amine adduct follows strict batch-to-batch consistency protocols. Quality is monitored through key parameters including amine value, viscosity, and color to ensure reliable performance as a curing agent. Certificates of Analysis (COA) detailing assay, physical properties, and functional group content are provided with each shipment to support your formulation and quality assurance processes.

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 performance. Keep away from heat sources and open flame.
