Description

Silanetriol, Propyl-, Homopolymer is a specialized organosilicon compound, a homopolymer of propylsilanetriol. This product is valued for its ability to function as a reactive silanol source and coupling agent, offering enhanced compatibility and adhesion promotion in composite systems. It is primarily utilized by manufacturers in the coatings, sealants, and advanced materials industries seeking to improve the interfacial properties between organic polymers and inorganic substrates. The compound is identified by CAS No. 36088-62-7.

Application

• Adhesion Promoter: Enhances bonding between organic resins (e.g., epoxies, polyurethanes) and inorganic surfaces like glass, metals, and minerals.
• Surface Modification: Used to treat fillers (silica, talc) and pigments to improve dispersion and reduce viscosity in polymer composites and masterbatches.
• Crosslinking Agent: Serves as a co-reactant in silicone resin formulations and room-temperature vulcanizing (RTV) systems to modify network structure and properties.
• Water Repellency: Imparts hydrophobic characteristics to construction materials, textiles, and stone.
• Primer Formulation: A key component in primers for coatings and adhesives where superior wet adhesion and corrosion resistance are required.
• Release Coatings: Used in the formulation of non-stick and release coatings for industrial applications.
• Composite Materials: Improves the mechanical properties and durability of fiber-reinforced plastics (FRP) and nanocomposites.

Quality Control

Our Silanetriol, Propyl-, Homopolymer is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as silanol content, molecular weight distribution, and purity. Certificates of Analysis (COA) documenting these specifications are available upon request. We adhere to relevant industry standards and can support compliance needs for various industrial applications.

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