Description

Siloxanes And Silicones, Di-Me, Polymers With 3-(2-Aminoethyl)Aminopropyl Ph Silsesquioxanes, Methoxy-Terminated is a specialized functionalized silicone polymer that combines the flexibility and thermal stability of polydimethylsiloxane (PDMS) with the reactive amino and silsesquioxane groups. This unique hybrid structure is engineered to provide superior adhesion, compatibility, and crosslinking capabilities in demanding formulations. It is a critical performance additive for industries requiring enhanced material properties, such as improved surface wetting, mechanical reinforcement, and chemical resistance. This product is supplied under CAS No. 477725-72-7.

Application

• Advanced Adhesives & Sealants: Acts as a coupling agent and adhesion promoter, particularly for bonding silicone materials to difficult substrates like metals, glass, and plastics.
• High-Performance Coatings: Used to improve surface wetting, scratch resistance, and durability in protective and release coatings.
• Reinforced Composites & Resins: Serves as a compatibilizer and surface modifier for fillers (e.g., silica, carbon fibers) in epoxy, polyimide, or other thermoset matrices to enhance mechanical properties.
• Specialty Elastomers: Incorporated into silicone rubber formulations to modify crosslink density and improve tear strength and heat resistance.
• Electronics Encapsulation: Utilized in potting compounds and conformal coatings for electronic components due to its potential for thermal stability and moisture resistance.
• Personal Care & Cosmetic Ingredients: Functions as a film-forming agent and conditioner in hair care and skincare products, providing a smooth, non-greasy feel.

Quality Control

Our production of this advanced silicone hybrid adheres to strict quality management protocols. Each batch is characterized using analytical techniques such as NMR, FT-IR, and GPC to confirm structure, functional group content, and molecular weight distribution. Certificates of Analysis (COA) detailing key parameters like amine value, viscosity, and non-volatile content are provided to ensure batch-to-batch consistency and performance reliability for your formulation needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) when not in use to prevent moisture absorption and premature reaction.
