Di-Tert-Butoxy-Diacetoxysilane Bulk Price Specs & Data
Essential Di-tert-butoxy-diacetoxysilane Specs for Industrial Quality Control
Di-tert-butoxy-diacetoxysilane (CAS: 13170-23-5) functions as a critical Acetoxysilane crosslinker in high-performance silicone formulations. Procurement teams must verify physical constants against certified COAs to ensure batch consistency. The material typically presents as a colorless to light yellow transparent liquid with a characteristic acetic odor, indicative of its hydrolytic potential. Key quality control parameters include density, refractive index, and active content, which directly influence curing kinetics in RTV-1 systems.
At NINGBO INNO PHARMCHEM CO.,LTD., quality assurance protocols focus on GC-MS purity profiles and hydrolysis stability rather than generic regulatory claims. Variations in active content significantly impact the stoichiometry of the curing reaction. Lower purity grades may contain residual alcohols or hydrolysis byproducts that interfere with adhesion promotion on metal substrates. The following table outlines the critical specification ranges observed in industrial supply chains, distinguishing between standard and high-purity grades.
| Parameter | Standard Industrial Grade | High Purity Grade | Test Method |
|---|---|---|---|
| Appearance | Colorless to Yellow Liquid | Colorless Transparent Liquid | Visual / APHA |
| Active Content | ≥ 85% | ≥ 95% | GC-MS |
| Density (25°C) | 1.015 - 1.025 g/ml | 1.020 g/ml | ASTM D4052 |
| Refractive Index (25°C) | 1.4030 - 1.4050 | 1.4040 | ASTM D1218 |
| Boiling Point | 102°C @ 5mmHg | 102°C @ 5mmHg | Distillation |
| Flash Point | 95°C | 95°C | PMCC |
Maintaining a refractive index near 1.4040 and density at 1.02 g/ml confirms the structural integrity of the silane backbone. Deviations often signal contamination or partial hydrolysis during storage.

Understanding Di-tert-butoxy-diacetoxysilane Bulk Price Structures and MOQ
Bulk pricing for this specialty chemical is driven by raw material volatility, specifically silicon metal and acetic acid derivatives, alongside purification costs. Market rates fluctuate based on the required active content; achieving ≥95% purity demands additional distillation steps compared to standard ≥85% grades. Procurement contracts typically tier pricing based on volume commitments, with significant discounts applied to full container load (FCL) orders versus less than container load (LCL) shipments.
Minimum Order Quantities (MOQ) are structured around standard packaging units to optimize logistics. Suppliers generally enforce MOQs aligned with 200kg drum multiples or IBC containers. Price structures also account for hazard classification during transport, as the material is flammable and moisture-sensitive. Long-term supply agreements often lock in pricing to mitigate exposure to upstream chemical feedstock swings. Buyers should request quotes specifying the desired purity grade, as the cost differential between industrial grade and high-purity variants reflects the additional processing required to remove hydrolysis byproducts.
Safe Storage and Bulk Packaging Options for Di-tert-butoxy-diacetoxysilane
Proper storage is critical due to the compound’s strong hydrolytic activity. Di-tert-butoxy-diacetoxysilane reacts readily with atmospheric moisture without catalysts, releasing acetic acid. Consequently, containers must remain tightly sealed in a dry, ventilated environment away from direct sunlight. The recommended shelf life is 12 months when stored under these conditions. Once opened, containers require careful resealing and should be kept upright to prevent leakage and minimize headspace exposure to humid air.
Standard bulk packaging includes 200kg lined steel drums or 1000kg IBC containers. For extended storage or sensitive climates, nitrogen blanketing is advised to displace moisture within the container headspace. Warehouse facilities must maintain temperature stability to prevent condensation inside drums during thermal cycling. Compliance with local fire codes is necessary given the 95°C flash point. Improper storage leads to polymerization or gelation within the container, rendering the Adhesion Promoter ineffective for downstream formulation.
Optimizing Di-tert-butoxy-diacetoxysilane Dosage for RTV Adhesion Promoters
In RTV-1 silicone sealant formulations, this silane serves as a primary Crosslinker and adhesion promoter. The typical dosage ranges from 0.3% to 0.5% by weight relative to the total polymer mass. This concentration is sufficient to promote caking properties on aluminum and other metal base materials without compromising the physical properties of the cured elastomer. Excessive dosage can lead to accelerated surface curing, resulting in skinning issues or reduced working time.
The hydrolysis activity sits between alkoxysilanes and chlorosilanes, allowing for room temperature curing without additional catalysts. Formulators must balance the acetic acid release rate with the desired cure profile. For comprehensive technical details on integrating this chemical into specific polymer matrices, refer to the Di-tert-butoxy-diacetoxysilane RTV Silicone Formulation Guide. Precision in dosing ensures optimal bond strength while maintaining the elasticity required for structural glazing and sealing applications.
How to Request Di-tert-butoxy-diacetoxysilane Samples for Specification Testing
Sample acquisition is a technical validation step rather than an administrative process. Procurement teams utilize samples to verify GC-MS purity limits, density, and refractive index against internal quality standards. When evaluating a new supply source, the focus must remain on the chemical data within the COA rather than the logistics of delivery. Samples are typically shipped via international express in compliant hazardous material packaging to ensure integrity upon arrival.
Testing protocols should include hydrolysis stability checks and compatibility trials with existing base polymers. This data confirms whether the material acts as a viable drop-in replacement for current supply chains. Engineers often compare performance benchmarks against established equivalents to validate consistency. For further analysis on substituting existing materials without reformulating the entire system, consult the Di-tert-butoxy-diacetoxysilane Equivalent For Rtv technical brief. Validation ensures that the Industrial Grade material meets the rigorous demands of high-volume manufacturing.
Supply chain reliability for Di-tert-butoxy-diacetoxysilane depends on verified specifications and consistent manufacturing processes.
