Description

1-Propanaminium, N,n-Dimethyl-n-[3-(Trimethoxysilyl)Propyl]-3-[[(2,4,6-Trimethylphenyl)Sulfonyl]Amino]-, Chloride (1:1) is a sophisticated, multi-functional silane quaternary ammonium compound designed for advanced surface modification and adhesion promotion. This specialty chemical is engineered to deliver superior performance by combining cationic activity with hydrolyzable silane functionality in a single molecule. It is a critical component for formulators and manufacturers in the coatings, adhesives, and advanced materials sectors seeking to enhance substrate compatibility, durability, and interfacial bonding.

Application

• Adhesion Promoter for Coatings: Significantly improves the adhesion of paints, inks, and polymer coatings to challenging substrates like metals, glass, and plastics.
• Surface Modifier for Fillers & Pigments: Used to treat inorganic fillers (e.g., silica, glass fibers) and pigments to improve dispersion in organic matrices and enhance composite mechanical properties.
• Antistatic & Antimicrobial Agent: Imparts durable antistatic properties to synthetic fibers and plastics; the quaternary ammonium group provides potential for antimicrobial surface treatments.
• Coupling Agent in Sealants & Adhesives: Enhances bond strength and moisture resistance in silicone, polyurethane, and epoxy-based formulations.
• Fiber Sizing for Composites: Acts as a key component in sizing formulations for glass and carbon fibers to optimize the fiber-matrix interface in reinforced composites.
• Primer Formulations: Serves as an active ingredient in surface primers to prepare substrates for subsequent coating or bonding applications.

Quality Control

Every batch of our specialty silane is produced under strict quality management protocols to ensure consistency and performance. We employ advanced analytical techniques including NMR, HPLC, and FTIR for precise identification and purity verification. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and key physical parameters is provided with each shipment, ensuring full traceability and compliance with your technical requirements.

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 product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from strong acids and bases.
