UV-400 Liquid Bulk Price Specification & Tech Data
Differentiating UV-400 Liquid Chemical Additives from Automotive Window Films
Procurement teams often encounter confusion between UV-400 liquid chemical additives and consumer automotive window films due to overlapping terminology in search results. The target material for industrial sourcing is CAS 153519-44-9, a Hydroxyphenyltriazine derivative designed as a liquid automotive paint additive. In contrast, window films are laminated PET structures applied to glass surfaces. This distinction is critical for formulation engineers specifying raw materials for coating systems versus facility managers purchasing installed glazing solutions.
The chemical additive functions as a HPT UV stabilizer incorporated directly into resin matrices, such as polyurethane, acrylic, or epoxy systems. It operates at a molecular level to absorb high-energy ultraviolet radiation before it can degrade the polymer backbone. Window films, conversely, act as a physical barrier post-manufacturing. When sourcing for coating production, the focus must remain on liquid bulk specifications, including viscosity, density, and spectral transmittance, rather than the optical properties of finished films. Misidentifying these categories leads to significant supply chain errors, as the handling requirements and integration methods differ fundamentally.
UV-400 Liquid Bulk Price Structure and Volume Discount Tiers
Bulk pricing for UV-400 liquid is determined by purity grades, packaging configurations, and order volume. Standard commercial grades typically maintain a purity threshold of ≥85% via HPLC analysis. Pricing tiers generally shift at volume breakpoints, such as 200kg, 1000kg, and full isotank quantities. Higher purity batches, often required for optical coatings or high-clarity automotive finishes, may command a premium due to additional distillation or filtration steps during synthesis.
At NINGBO INNO PHARMCHEM CO.,LTD., cost structures are aligned with long-term supply agreements rather than spot market fluctuations. Procurement managers should anticipate volume discounts when committing to quarterly or annual contracts. It is essential to clarify Incoterms early in the negotiation process, as freight costs for hazardous liquids can significantly impact the landed cost per kilogram. Additionally, custom synthesis requests for modified alkyl chain lengths to improve compatibility with specific solvent systems will affect the unit price based on reactor time and raw material availability.
Detailed Technical Specifications and Purity Metrics for UV-400 Sourcing
Technical due diligence for this light stabilizer requires verification of physical constants and performance benchmarks. The material appears as a yellow viscous liquid with low volatility, ensuring it remains within the coating matrix during curing and service life. Key quality indicators include ash content, density at standard temperature, and spectral transmittance in the visible range to prevent yellowing.
The following table outlines the critical parameters for qualifying UV-400 liquid batches against industry standards for a reliable drop-in replacement:
| Parameter | Specification Standard | Typical Test Method |
|---|---|---|
| CAS Number | 153519-44-9 | Verified |
| Appearance | Yellow Viscous Liquid | Visual / ASTM D1209 |
| Purity (HPLC) | ≥ 85% | High-Performance Liquid Chromatography |
| Density (20°C) | 1.07 g/cm³ ± 0.02 | ASTM D4052 |
| Ash Content | ≤ 0.1% | Gravimetric Analysis |
| Transmittance (460 nm) | ≥ 95% | UV-Vis Spectrophotometry |
| Transmittance (500 nm) | ≥ 97% | UV-Vis Spectrophotometry |
| Thermal Stability | Stable up to 300°C | TGA Analysis |

Consistency in these metrics ensures that the additive performs effectively in high bake system environments without decomposing or migrating to the surface.
Procurement Essentials: MOQ, Packaging, and Supply Chain Stability for UV-400
Standard packaging for UV-400 liquid typically involves 20kg plastic drums, though bulk containers such as IBCs are available for high-volume manufacturing lines. Minimum Order Quantities (MOQ) vary based on whether the stock is ex-warehouse or made-to-order. For ex-warehouse shipments, MOQs may be as low as one drum, whereas custom production runs usually require a minimum of 200kg to justify reactor setup.
Supply chain stability is maintained through diversified raw material sourcing and buffered inventory levels. Procurement teams should request lead time estimates based on their specific destination port. For formulators optimizing cure cycles, referencing the UV Absorber UV-400 Liquid Formulation Guide High Bake 2026 provides critical data on integration temperatures and solvent compatibility. Proper storage conditions require keeping containers sealed in a cool, dry environment to prevent moisture absorption, which can affect viscosity and handling characteristics during dispensing.
Regulatory Compliance and Safety Data Requirements for UV-400 Liquid Imports
Importing chemical additives requires strict adherence to safety documentation and quality assurance protocols. Every shipment must be accompanied by a Certificate of Analysis (COA) verifying the batch-specific purity and physical properties against the specifications listed above. Additionally, a Safety Data Sheet (SDS) compliant with GHS standards is mandatory for logistics and handling safety.
While regulatory frameworks vary by region, the focus for procurement should be on the chemical data within the COA, such as GC-MS purity limits and heavy metal content. For teams evaluating this material against existing legacy stabilizers, the UV Absorber UV-400 equivalent for automotive paint data offers comparative performance metrics. NINGBO INNO PHARMCHEM CO.,LTD. ensures all documentation supports smooth customs clearance and internal quality audits without relying on unverified regulatory claims.
Ensuring the supply chain provides consistent GC-MS profiles prevents batch-to-batch variation that could compromise coating durability. Procurement specifications should explicitly mandate the submission of these analytical reports prior to shipment release.
