Description

2,2-Dimethyl-1,3-Propanediol, Ethoxylated is a versatile polyol ether derivative, valued for its unique combination of a rigid neopentyl glycol core and flexible polyether side chains. This structure makes it an excellent building block and performance additive, offering enhanced solubility, hydrophilicity, and reactivity control. It is primarily sought after by formulators in the polymer, coatings, and specialty chemical industries for synthesizing high-performance resins, surfactants, and plasticizers.

Application

• Polymer Synthesis: A key monomer for producing modified polyester and alkyd resins with improved flexibility and weatherability.
• Coatings & Inks: Used as a reactive diluent and modifier in polyurethane and epoxy systems to adjust viscosity, enhance adhesion, and reduce volatility.
• Surfactants & Emulsifiers: Serves as a hydrophilic intermediate for the synthesis of non-ionic surfactants used in detergents and agrochemical formulations.
• Plasticizers: Imparts low-temperature flexibility and permanence in PVC and other polymer compounds.
• Personal Care: Functions as a humectant and solvent in cosmetic and personal care products due to its moisture-binding properties.
• Lubricants & Functional Fluids: Acts as a base fluid or additive in synthetic lubricants, offering thermal stability and low pour points.

Quality Control

Our 2,2-Dimethyl-1,3-Propanediol, Ethoxylated is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, hydroxyl value, and molecular weight distribution. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality.
