Description

2,2'-[[2,2-Dimethyl-1-(1-Methylethyl)Propane-1,3-Diyl]Bis(Oxy)]Bisethanol is a specialized branched-chain polyether diol, a versatile chemical intermediate prized for its unique sterically hindered structure. This compound matters for its ability to impart flexibility, hydrophilicity, and tailored reactivity into polymer backbones, enhancing performance in demanding formulations. It is primarily needed by manufacturers in the polyurethane, coatings, and specialty polymer industries seeking to develop advanced materials with specific physical properties.

Application

• Polyurethane Synthesis: A key monomer for producing flexible and specialty polyols, used in elastomers, coatings, and adhesives.
• Polymer Modification: Acts as a chain extender or cross-linking agent to modify the flexibility, hydrophilicity, and thermal properties of polyesters and polyethers.
• Surface Coatings & Resins: Incorporated into alkyd and other resin formulations to improve film flexibility, adhesion, and chemical resistance.
• Lubricant & Fuel Additives: Serves as a precursor for synthesizing additives that improve viscosity index, detergency, and anti-wear properties.
• Pharmaceutical & Cosmetic Intermediates: Used in the synthesis of non-ionic surfactants and emulsifiers for personal care products.
• Plasticizer Production: A building block for creating polymeric plasticizers that offer low volatility and good compatibility with PVC and other polymers.

Quality Control

Our 2,2'-[[2,2-Dimethyl-1-(1-Methylethyl)Propane-1,3-Diyl]Bis(Oxy)]Bisethanol is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity and performance. Certificates of Analysis (COA) documenting key parameters such as assay, hydroxyl value, and moisture content are provided and available upon request to support your 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); containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
