Source colorless triisopropylsilyl acrylate for coatings, adhesives, and resins

Strategic Sourcing Guide for Colorless Triisopropylsilyl Acrylate

Understanding the Chemical Profile and Physical Attributes

Sourcing colorless triisopropylsilyl acrylate requires a precise understanding of the specific chemical identity and its physical manifestations in the supply chain. While the core keyword points to a specialized silyl-protected acrylate monomer, buyers must distinguish this from the broader category of acrylate derivatives often found in general chemical catalogs. The target molecule is characterized by its role as a protecting group in polymer chemistry, specifically designed to modify reactivity and solubility in advanced coating and adhesive formulations.

In the context of available market data, acrylate-based products frequently appear with varying physical states. The supplied facts indicate that acrylate products can manifest as liquids, crystals, powders, or transparent substances. For triisopropylsilyl acrylate specifically, the expectation is a colorless transparent liquid, aligning with the general observation of "Colorless transparent liquid" found in high-purity acrylate listings. However, buyers must verify this against the specific batch, as some listings in the broader acrylate sector note appearances ranging from "Crystal" to "Liquid." The density of similar acrylate compounds is often observed around 0.887 g/cm³, with boiling points typically falling in the range of 215-218 °C at standard atmospheric pressure. These physical parameters are critical for logistics planning, particularly regarding storage temperature, which is generally recommended to be below 30 °C to maintain stability.

The molecular weight of standard acrylate monomers in this class often registers around 184.28 g/mol, though the addition of the triisopropylsilyl group significantly alters this figure. Buyers should not assume the molecular weight of a standard acrylate applies to the silylated variant without explicit confirmation. The CAS number is a definitive identifier; while the provided data lists 21142-29-0 for specific silane coupling agents, the unique CAS for triisopropylsilyl acrylate must be cross-referenced to ensure the correct chemical structure is being procured. Misidentification in this sector can lead to significant failures in downstream polymerization processes.

Technical Specifications and Purity Standards

When evaluating technical specifications for colorless triisopropylsilyl acrylate, the focus must shift from general industrial grades to high-purity requirements suitable for specialized applications. The supplied facts highlight that purity standards in the acrylate sector vary widely, with some products listed at "Purity >97%" and others at "Purity ≥99.5%." For a silyl-protected monomer intended for high-performance applications, a purity level of 99% or higher is typically the baseline expectation to prevent side reactions during polymerization.

The grade standard is another critical specification. The market data indicates the existence of multiple grade standards, including Agriculture grade, Electron grade, Food grade, Industrial grade, Medicine grade, and Reagent grade. For colorless triisopropylsilyl acrylate, the relevant grade is almost exclusively Industrial or Reagent grade, depending on the intended application in research or manufacturing. The presence of "Crude," "Industrial," "Refined," and "Technical" quality descriptors in general listings suggests that buyers must explicitly request "Refined" or "Technical" grades to ensure the absence of impurities that could affect the stability of the silyl group.

Water content is a vital parameter for acrylate monomers, as moisture can trigger premature polymerization or hydrolysis of the silyl protecting group. The provided data notes a water content specification of "≤ 0.05 %" for certain high-grade acrylates. This serves as a benchmark for what a buyer should demand from a supplier of triisopropylsilyl acrylate. Similarly, the acid value, listed as "≤ 0.1 Mg KOH/G" in the reference data, indicates the need for low acidity to prevent catalyst poisoning in subsequent reactions. Buyers should verify that the supplier provides a Certificate of Analysis (CoA) confirming these specific thresholds, rather than relying on general product descriptions.

Compliance, Safety, and Regulatory Verification

Navigating the compliance landscape for colorless triisopropylsilyl acrylate involves rigorous checks on safety data and regulatory adherence. The supplied facts mention several safety parameters, including a flash point of 82 °C, an auto-ignition temperature of 280 °C, and explosion limits ranging from 0.8% to 6.4%. These figures are indicative of the flammability and handling risks associated with acrylate monomers. While these specific numbers may belong to a different acrylate variant in the dataset, they establish the type of safety data that must be present for the target chemical.

Buyers must ensure that the supplier provides a Safety Data Sheet (SDS) that aligns with international standards such as GHS (Globally Harmonized System). The presence of "Oil-Solution" as a property in the data suggests that the product may be supplied in a solvent or require specific handling to prevent oxidation or degradation. The "Antistatic" and "Antirust" special functions listed in the source data are not typical for the raw monomer itself but may be relevant for the final formulation. Therefore, buyers should not expect the raw triisopropylsilyl acrylate to possess these functions inherently unless specified as a pre-formulated product.

Regulatory compliance also extends to the origin of the product. The data indicates origins in "P. R. China," "Chna," and "South Africa." While the specific origin of triisopropylsilyl acrylate is not explicitly stated in the provided facts, buyers must verify the country of origin to ensure compliance with import regulations, particularly regarding chemical restrictions in the destination market. The "Grade Standard" of "Industrial Grade" or "Reagent grade" must be clearly stated on the commercial invoice and shipping documents to avoid customs delays.

Cost Drivers and Procurement Economics

The cost structure for colorless triisopropylsilyl acrylate is influenced by several factors, including the complexity of synthesis, purity requirements, and packaging. The observed price range in the general acrylate market spans from 0.5 to 1500 USD, a wide variance that reflects the difference between bulk industrial commodities and specialized fine chemicals. For a silyl-protected acrylate, the price will likely be on the higher end of this spectrum due to the specialized nature of the silylation process.

Minimum Order Quantity (MOQ) is a significant economic driver. The data shows an MOQ range of 1 to 1000 units, with specific listings indicating an MOQ of "1 Ton" for certain acrylates. For smaller research or pilot-scale projects, buyers should look for suppliers offering "Small Orders: Accepted" or flexible packaging options. The standard packaging observed is the "200L Drum" or "200kg Drum," with some variations like "180kg/ Drum." Selecting the appropriate packaging size can impact the effective unit cost, especially for buyers who do not require full drum quantities.

Lead times and availability are also critical cost considerations. While specific lead times are not provided in the data, the "Manufacturing Stage" usage implies that the product is often produced on demand or in batches. Buyers should anticipate that specialized chemicals may have longer lead times compared to commodity chemicals. The "Customization: Available" attribute suggests that suppliers may offer tailored packaging or purity levels, which could incur additional costs but may be necessary for specific project requirements.

Typical Applications and Functional Integration

Colorless triisopropylsilyl acrylate finds its primary utility in advanced material science, particularly in the synthesis of specialty polymers and coatings. The supplied facts list applications such as "Appliance Paint," "Building Coating," and "Car Paint," which are typical for acrylate-based systems. However, the specific role of the triisopropylsilyl group is to provide temporary protection during polymerization, allowing for controlled reactivity that can be removed later to reveal functional groups.

The product is classified under "Coating Auxiliary Agents" and "Plastic Auxiliary Agents," indicating its use as a modifier or additive in these sectors. The "Oil Type Coating Auxiliary Agent" designation suggests compatibility with oil-based resin systems. In the context of "Water Treatment Chemicals" and "Rubber Auxiliary Agents," the acrylate monomer may serve as a cross-linking agent or a modifier to enhance durability and resistance. The "Antistatic" and "Antirust" functions mentioned in the data are likely outcomes of the final polymer formulation rather than properties of the raw monomer, highlighting the importance of understanding the downstream application when sourcing.

Supplier Evaluation and Quality Assurance

Evaluating suppliers for colorless triisopropylsilyl acrylate requires a multi-faceted approach focusing on technical capability and quality assurance. The "Brand Name" and "Model Number" fields in the data (e.g., "FLIUXMAT," "KH-571," "SCA-R73M") illustrate the variety of product identifiers used in the market. Buyers should not rely on these specific identifiers for the target chemical but should use them as a reference for the level of detail a reputable supplier should provide.

Quality control is paramount. The "Standard" field in the data lists "Purity >97%" and "Purity ≥99.5%," serving as benchmarks for the verification process. Buyers should request batch-specific CoAs that confirm the molecular weight, boiling point, density, and water content against the expected values. The "Viscosity" of 1.5 MPa·S and "Vapor Pressure" of 0.03 Hpa are additional parameters that should be verified to ensure the product meets the required physical specifications for the intended application.

Supplier reliability can be assessed by their willingness to provide detailed technical data and their adherence to "Grade Standard" specifications. The presence of "Small Orders: Accepted" indicates a supplier's flexibility, which is valuable for buyers in the early stages of product development. However, buyers must balance this with the need for consistent quality, ensuring that the supplier maintains rigorous control over their production processes to avoid batch-to-batch variability.

Long-Term Procurement and Supply Chain Stability

Securing a long-term supply of colorless triisopropylsilyl acrylate involves more than just finding a single transaction; it requires building a resilient supply chain. The "Usage Stage" is identified as "Manufacturing Stage," indicating that the chemical is an intermediate in a larger production process. Disruptions in the supply of this monomer can halt downstream manufacturing, making supplier stability a critical factor.

Buyers should consider the "Origin" of the product, with "China" and "South Africa" being noted origins in the data. Diversifying the supplier base across different geographic regions can mitigate risks associated with geopolitical instability or logistical disruptions. The "Customization: Available" attribute suggests that suppliers may be willing to adapt their production to meet specific volume or packaging needs, which can be leveraged for long-term contracts.

Furthermore, the "Storage Temperature" recommendation of "< 30 °C" highlights the need for proper logistics infrastructure. Buyers must ensure that their storage facilities and transportation partners can maintain these conditions to prevent degradation of the product. Regular audits of the supplier's quality management systems and adherence to "Industrial Grade" or "Reagent Grade" standards will help maintain the integrity of the supply chain over time. By focusing on these long-term considerations, buyers can ensure a steady and reliable supply of colorless triisopropylsilyl acrylate for their critical applications.
