Bis(3-Triethoxysilylpropyl)Amine Bulk Procurement Specs
Defining Critical Physical Constants for Bis(3-triethoxysilylpropyl)amine Bulk Procurement Specs
Procurement of Bis(3-triethoxysilylpropyl)amine requires strict adherence to physical constants that dictate performance in polymer matrices and adhesive formulations. This amino silane functions primarily as an adhesion promoter and cross-linker, where deviations in purity or viscosity can compromise bond strength and cure rates. Industrial buyers must verify the molecular formula C18H43NO6Si2 and a molecular weight of 425.71 g/mol to ensure stoichiometric accuracy in reaction calculations.
The appearance should be a clear liquid, ranging from colorless to light yellow. Darkening often indicates oxidation or contamination, which affects the reactivity of the amino group. For high-performance applications, the purity must meet or exceed 95%. Lower purity grades introduce impurities that can act as plasticizers or inhibit curing in epoxy and polyurethane systems. The refractive index at 20°C is typically 1.4265, serving as a rapid identity check during incoming quality control.
Viscosity is a critical parameter for automated dispensing systems. At 25°C, the viscosity should measure approximately 5.5 cSt. Deviations here impact flow characteristics in coating lines and mixing efficiency in bulk compounding. The density stands at 0.97 g/mL, which is essential for converting volume-based orders to mass-based inventory records. Below is a comparison of standard industry parameters against high-purity specifications required for critical manufacturing:
| Parameter | Standard Industry Range | High-Purity Specification | Test Method |
|---|---|---|---|
| Purity | 90% - 95% | ≥ 95% | GC-MS |
| Viscosity (25°C) | 5.0 - 7.0 cSt | 5.5 cSt | Brookfield |
| Density (25°C) | 0.96 - 0.98 g/mL | 0.97 g/mL | ASTM D4052 |
| Refractive Index (20°C) | 1.420 - 1.430 | 1.4265 | ASTM D1218 |
| Boiling Point | 155 - 165°C @ 0.6 mmHg | 160°C @ 0.6 mmHg | Distillation |
When evaluating suppliers, request a Certificate of Analysis (COA) that explicitly lists GC-MS chromatograms. This ensures the absence of mono-substituted byproducts or hydrolysis products that degrade shelf life. For detailed specifications on this Bis[(3-Triethoxysilyl)Propyl]amine Silane Coupling Agent, technical datasheets should be reviewed prior to trial batches.
Validating Regulatory Compliance Including TSCA Status and EINECS Number 236-818-1
Regulatory validation is a non-negotiable step in the procurement of specialty chemicals for import into North American and European markets. The substance is listed under the Toxic Substances Control Act (TSCA) inventory, confirming its eligibility for commercial use in the United States. Procurement teams must verify the TSCA status on the COA to prevent customs delays at US ports. Inventory status indicates the chemical is not subject to Pre-Manufacture Notice (PMN) requirements for standard industrial applications.
In European markets, identification relies on the EINECS Number 236-818-1. This identifier is used for safety data sheet (SDS) compilation and inventory tracking within supply chain management systems. While regulatory landscapes shift, maintaining accurate chemical identification numbers ensures continuity in compliance documentation. NINGBO INNO PHARMCHEM CO.,LTD. maintains rigorous documentation standards to support these regulatory requirements without compromising shipment velocity.
It is critical to distinguish between inventory listing and specific regulatory certifications. Buyers should focus on the chemical identity confirmation via CAS and EINECS rather than assuming broad compliance certifications that may not apply to specific downstream uses. Always cross-reference the CAS 13497-18-2 with your internal restricted substance lists (RSL) to ensure alignment with corporate sustainability goals.
Assessing Hazardous Material Risks Using HMIS 3-1-1-X and Flash Point Data
Safety management during storage and handling depends on accurate hazard classification. The Hazardous Materials Identification System (HMIS) rating for this amino silane is typically 3-1-1-X. This indicates a health hazard rating of 3, requiring proper ventilation and personal protective equipment (PPE) such as chemical-resistant gloves and eye protection. The flammability rating of 1 suggests the material is combustible but not highly flammable under standard ambient conditions.
The Flash Point is 162 °C, classifying the material as a combustible liquid rather than a flammable liquid under many transport regulations (e.g., DOT Class 3 thresholds often start lower). However, storage areas must still be equipped with fire suppression systems suitable for chemical fires. The reactivity rating of 1 indicates stability under normal conditions, but the material should be kept away from strong oxidizing agents and acids to prevent violent reactions or premature hydrolysis.
Moisture sensitivity is a key handling consideration. As an alkoxysilane, exposure to atmospheric humidity can initiate hydrolysis, leading to polymerization and viscosity increases over time. Containers must be tightly sealed and stored in a cool, dry environment. Nitrogen blanketing is recommended for bulk storage tanks to exclude moisture and oxygen, preserving the integrity of the amino functionality. Safety data sheets must be accessible to all personnel handling the material, emphasizing the irritant nature of the amine group.
Aligning CAS 13497-18-2 Supply with Automotive and Alternative Energy Manufacturing Needs
The application profile for Bis(3-triethoxysilylpropyl)amine extends across high-growth sectors including automotive, alternative energy, and medical devices. In automotive manufacturing, this silane is utilized in primer formulations for glass bonding and structural adhesives. The dual amino functionality provides superior adhesion to substrates such as steel, aluminum, and glass, enhancing durability against humidity and thermal cycling.
Alternative energy sectors, including photovoltaic modules and wind turbines, rely on this chemistry for encapsulant adhesion and composite resin modification. The ability to form covalent bonds with inorganic surfaces improves the longevity of solar panels exposed to harsh environmental conditions. For manufacturers seeking a Bis[(3-Triethoxysilyl)Propyl]amine Dynasylan 1122 Equivalent For Spur Adhesives, consistency in supply chain logistics is as vital as chemical performance.
Medical and healthcare applications, such as surgical devices and dental implants, require ultra-high purity grades to meet biocompatibility standards. The chemical acts as a coupling agent in composite resins used for restorative materials. Supply chain resilience is critical here; any interruption can halt production lines for critical devices. Manufacturers should qualify multiple sources and maintain safety stock based on lead times and consumption rates. The versatility of this amino silane allows it to serve as a drop-in replacement in existing formulations where adhesion promotion is the primary failure mode.
Optimizing Logistics Through Custom Bulk Packaging and Quality Assurance Documentation
Logistics optimization for bulk chemical procurement involves selecting packaging that preserves product integrity while minimizing handling costs. Standard packaging options include 200kg drums and ISO tanks for large-volume requirements. For NINGBO INNO PHARMCHEM CO.,LTD. clients, custom packaging solutions are available to align with specific dispensing equipment and warehouse constraints. Proper labeling must include the CAS number, hazard symbols, and batch numbers for traceability.
Quality assurance documentation is the backbone of bulk procurement. Every shipment must be accompanied by a batch-specific COA detailing the actual test results for purity, density, and refractive index. Retain samples should be kept for every batch received to facilitate root cause analysis in the event of downstream processing issues. GC-MS data within the COA provides transparency regarding impurity profiles, allowing formulators to adjust catalyst levels if necessary.
Shipping classification should be verified prior to booking freight. While the flash point suggests combustible liquid status, regional variations in transport regulations may apply. Ensure the SDS provided matches the destination country's regulatory language requirements. Efficient logistics also involve coordinating delivery schedules with production runs to minimize on-site storage time, reducing the risk of container compromise. By integrating quality data with logistics planning, manufacturers can ensure a steady supply of critical raw materials without compromising safety or compliance.
