Description

Silane, (3-Chloropropyl)dimethyl(2-propen-1-yloxy)- is a highly reactive organosilicon compound featuring both a chloropropyl and an allyloxy functional group. This dual functionality makes it a valuable versatile coupling agent and intermediate for creating hybrid organic-inorganic materials. It is primarily needed by manufacturers in the silicone polymers, advanced adhesives, and surface modification sectors seeking to enhance material compatibility and performance.

Application

• Surface Modification Agent: Used to functionalize inorganic surfaces like glass, silica, and metals to improve adhesion with organic polymers.
• Silicone Crosslinker & Modifier: Acts as a reactive site in silicone elastomers and resins, introducing chloropropyl and allyl functionalities for property tailoring.
• Adhesive & Sealant Formulation: Enhances the bonding strength and durability of high-performance adhesives, particularly for difficult-to-bond substrates.
• Polymer Synthesis Intermediate: Serves as a key building block for synthesizing specialty silane-modified polymers and copolymers.
• Filler Treatment: Improves the dispersion and interfacial bonding of mineral fillers (e.g., silica, clay) in composite materials.
• Release Coating Precursor: Used in the formulation of controlled-release coatings for industrial applications.

Quality Control

Our organosilane products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing key parameters such as purity, identity, and specific impurities. We adhere to a strict quality management system to guarantee the reliability required for your advanced material synthesis and manufacturing processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation.
