Description

Phenol, 4,4-(1-methylethylidene)bis-, reaction products with diethylenetriamine, epichlorohydrin, polyethylene-polypropylene glycol 2-aminopropyl Me ether and polypropylene glycol monoglycidyl ether ether with pentaerythritol (4:1) is a specialized, multi-functional polymeric amine derivative designed for advanced material formulations. This compound is engineered to provide enhanced compatibility, reactivity, and performance in demanding industrial applications where standard additives fall short. It is a critical component for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producers of advanced composites and functional polymers seeking to improve material properties and processing characteristics.

Application

• Curing Agent & Crosslinker: Functions as a reactive hardener and crosslinking agent in epoxy resin systems for high-performance coatings, adhesives, and composite materials.
• Polymer Modification: Used to modify and toughen thermoset and thermoplastic polymers, improving impact resistance, flexibility, and adhesion to various substrates.
• Surface Active Agent: Acts as a surfactant and dispersing aid in pigment pastes, inks, and coating formulations to enhance stability and application properties.
• Reactive Diluent: Serves as a viscosity modifier and reactive diluent in epoxy systems, reducing volatile organic compound (VOC) content while maintaining mechanical performance.
• Adhesion Promoter: Improves the bond strength and durability of adhesives and sealants on challenging surfaces such as metals, plastics, and treated glass.
• Composite Matrix Component: Incorporated into the matrix of fiber-reinforced plastics (FRP) and composites to tailor cure profiles and final material properties.

Quality Control

Our production of this advanced polymeric amine adduct follows a rigorous quality management system to ensure batch-to-batch consistency and performance reliability. Key parameters such as amine value, equivalent weight, viscosity, and color are strictly monitored. Certificates of Analysis (COA) documenting these specifications are provided with each shipment. While not a pharmaceutical ingredient, our manufacturing controls align with principles of ISO 9001 quality standards to meet the exacting requirements of industrial material formulators.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C / 59-77°F). This product is easily oxidized; for long-term storage, consider keeping under an inert atmosphere (e.g., nitrogen blanket) to preserve reactivity. Keep away from heat, sparks, open flames, and strong oxidizing agents. Ensure containers are kept tightly sealed when not in use to prevent moisture absorption and contamination.
