Description

n-Ethylaminoisobutyl Terminated Polydimethylsiloxane, 8-12Cs is a specialized amino-functional silicone fluid, distinguished by its reactive terminal groups on a polydimethylsiloxane (PDMS) backbone. This unique structure provides exceptional compatibility and reactivity, making it a crucial intermediate for creating high-performance, durable materials. It is primarily sought after by formulators in the personal care, textile, and industrial coatings sectors who require advanced surface modification, adhesion promotion, and durable conditioning effects.

Application

• Hair Care Formulations: Acts as a substantive conditioning agent, providing long-lasting softness, shine, and manageability with improved resistance to wash-out.
• Textile Finishing: Used as a softener and modifier to impart durable, luxurious softness and improved handle to natural and synthetic fibers.
• Industrial & Protective Coatings: Enhances adhesion, flexibility, and surface slip properties in coatings, sealants, and release agents.
• Personal Care Products: Functions as an emulsifier and stabilizer in creams and lotions, improving texture and skin feel.
• Fiberglass Sizing: Serves as a coupling agent and lubricant to protect fibers and improve resin compatibility in composite materials.
• Polymers & Resins: Utilized as a reactive modifier to enhance the impact resistance and processing characteristics of various polymer systems.

Quality Control

Our n-Ethylaminoisobutyl Terminated Polydimethylsiloxane is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including verification of amine value, viscosity, and purity. A comprehensive Certificate of Analysis (COA) documenting all key parameters is provided with every shipment to guarantee compliance with your specifications.

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 hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
