Description

1,3-Propanediamine, N,n-Dimethyl-, Reaction Products With Polyethylene Glycol Mono-Me Ether, Polypropylene Glycol Mono-Bu Ether And Poly-Tdi is a specialized polyurethane prepolymer or surfactant intermediate, synthesized from a complex reaction of modified diamines and polyisocyanates with polyether chains. This compound is engineered to provide unique surface-active properties and reactivity, making it a valuable component in advanced material formulations. It is primarily utilized by manufacturers in the polyurethane, coatings, and specialty chemical industries seeking to modify surface characteristics, enhance compatibility, or introduce specific functional groups into their products.

Application

• Polyurethane Dispersions (PUDs): Acts as a key internal emulsifier or chain extender for producing stable, water-based polyurethane dispersions used in eco-friendly coatings and adhesives.
• Surface Modifiers & Wetting Agents: Imparts improved wetting, leveling, and substrate adhesion in high-performance coatings, inks, and paint formulations.
• Reactive Surfactant: Serves as a polymerizable surfactant in emulsion polymerization processes for acrylics, styrenics, and other latex systems.
• Crosslinking Agent: Used to introduce controlled crosslinking and improve mechanical properties like toughness and chemical resistance in cured polymer films.
• Textile & Leather Auxiliaries: Functions as a softening agent, antistatic agent, or finishing chemical to enhance fabric handle and performance.
• Adhesive & Sealant Formulations: Modifies rheology and improves the bonding strength and flexibility of polyurethane-based adhesives and sealants.

Quality Control

Our production of this advanced chemical intermediate adheres to strict batch-to-batch consistency protocols. Quality is verified through a suite of analytical methods including determination of NCO content, amine value, hydroxyl value, viscosity, and solids content. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with each shipment to ensure it meets your formulation 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 / 59-77°F). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent moisture absorption, which can affect product performance. Keep away from heat, sparks, and open flame.
