Description

Ethanol, 2,2-Oxybis-, Reaction Products With 3-(Triethoxysilyl)-1-Propanamine is a specialized organosilane coupling agent, identified by CAS number 152261-43-3. This compound is engineered to provide superior adhesion promotion and surface modification by creating a strong chemical bridge between inorganic substrates and organic polymers. It is essential for manufacturers requiring enhanced material performance, durability, and interfacial bonding strength. Key industries that rely on this advanced silane include advanced composites, high-performance coatings, and specialty adhesives.

Application

• As a coupling agent and adhesion promoter in fiberglass-reinforced plastics and composite materials.
• For surface pretreatment and priming of glass, metals, and minerals to improve coating adhesion and corrosion resistance.
• As a key additive in high-performance sealants, adhesives, and encapsulants to enhance bond strength and environmental durability.
• In the formulation of specialty paints and industrial coatings to ensure excellent substrate wetting and long-term performance.
• For modifying fillers and pigments (e.g., silica, clay) to improve their dispersion and compatibility within polymer matrices.
• In the production of moisture-curable systems where it acts as a crosslinker and stabilizer.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and should be stored in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed under a dry, inert atmosphere (e.g., nitrogen) when not in use to prevent degradation from moisture absorption. Keep away from strong bases and incompatible materials.
