UV-5151 Bulk Price And Specs: Industrial Grade Data
UV-5151 Technical Specifications, Solubility, and Chemical Properties
UV Absorber UV-5151 (CAS: 104810-48-2) is a synergistic blend of hindered amine light stabilizers (HALS) and liquid UV absorbers designed for high-performance coating systems. The material presents as a pale yellow liquid with low volatility, ensuring minimal loss during high-temperature curing processes. Technical procurement requires verification of physical constants against standard certificates of analysis (COA) to ensure batch-to-batch consistency in formulation viscosity and color stability.
The specific gravity of 1.11 g/mL at 25℃ indicates a dense liquid phase compatible with standard solvent-based resin systems. Viscosity measures approximately 960 cps at 25°C, facilitating easy pumping and metering in industrial mixing vessels without requiring significant heating. Color stability is critical for clear coats; UV-5151 maintains a Gardner color value of 4.1, minimizing yellowing in light-colored finishes. The vapor pressure remains below 1 mmHg at 20℃, confirming low evaporation rates during application and film formation.
Solubility profiles dictate compatibility with various resin backbones. UV-5151 exhibits high solubility in common organic solvents used in industrial paints and wood coatings. The following table details solubility limits at 20°C:
| Solvent | Solubility (g in 100 ml) |
|---|---|
| Butanol | >50 |
| Butyl Acetate | >50 |
| Ethyl Glycol | >50 |
| MEK (Methyl Ethyl Ketone) | >50 |
| Styrene | >50 |
| TMPTA | >50 |
| Water | <0.5 |
As indicated, the product is hydrophobic with water solubility below 0.5g/100ml, making it unsuitable for pure water-based emulsions without specific emulsification protocols. However, it integrates seamlessly into solvent-borne systems, UV-curable acrylates (TMPTA, Styrene), and hybrid formulations. Procurement teams should verify GC-MS purity data to confirm the absence of residual starting materials that could affect final film clarity.
UV-5151 Bulk Price Analysis and Volume-Based Discount Tiers
Bulk pricing for UV-5151 is driven by raw material synthesis costs, purification levels, and logistics volumes. Industrial buyers typically secure lower unit costs through tonnage commitments rather than drum-level purchases. Price fluctuations often correlate with the availability of precursor amines and triazine derivatives used in the synergistic blend. Manufacturers offering direct factory pricing eliminate distributor markups, providing a more stable cost structure for long-term contracts.
Volume-based discount tiers generally activate at Intermediate Bulk Container (IBC) levels, typically 1,000 kg units. Full tank load orders further reduce freight costs per kilogram. When evaluating quotes, procurement managers must compare net purity specifications. Lower-priced alternatives may contain higher levels of isomers or diluents that reduce effective active content, requiring higher dosage rates to achieve equivalent UV protection. Therefore, the cost-per-performance metric is more relevant than the raw price-per-kilogram.
Supply chain stability also influences pricing. Manufacturers with consistent production schedules can lock in rates for 6 to 12-month periods, shielding formulators from spot market volatility. Requesting a detailed cost breakdown including packaging (drum vs. IBC) and Incoterms is standard practice for accurate budget forecasting.
UV-5151 vs. Tinuvin 5151: Performance Equivalence and Cost Savings
In the industrial coatings sector, UV-5151 is frequently evaluated as a drop-in replacement for established market benchmarks. The formulation chemistry targets identical performance parameters regarding thermal stability and lightfastness. Comparative testing indicates that UV-5151 matches the spectral absorption profile and HALS synergy of equivalent grades, providing comparable protection against photo-oxidative degradation.
Key performance indicators include retention of gloss and color fidelity after accelerated weathering exposure (QUV testing). Formulations utilizing UV-5151 demonstrate similar resistance to chalking and cracking as other leading liquid stabilizer blends. The primary advantage lies in supply chain diversification and cost efficiency. By qualifying a secondary source with matching technical specifications, manufacturers mitigate risk associated with single-source dependency.
Cost savings are realized not only through competitive unit pricing but also through reduced logistics lead times. Domestic or regional manufacturing hubs can offer faster delivery windows compared to imported alternatives. Technical service support for formulation adjustments ensures that the transition between stabilizer sources does not compromise final product quality. Procurement teams should request side-by-side weathering data to validate equivalence before full-scale production switching.
Recommended Application Areas and Dosage Levels for UV-5151 in Industrial Coatings
UV-5151 is specifically engineered for wood coatings and general industrial paints where long-term exterior durability is required. The liquid form factor allows for homogeneous distribution within the resin matrix without the need for high-shear dispersion equipment required for powder additives. This ensures consistent protection throughout the cured film thickness.
Recommended dosage levels typically range between 1% and 4% of the total formulation weight, depending on the substrate and performance requirements. For clear wood varnishes, lower dosage rates (1-2%) are often sufficient to maintain transparency while preventing lignin degradation. For pigmented industrial enamels exposed to harsh UV environments, dosage may increase to 3-4% to maximize service life. Over-dosing should be avoided as it can lead to surface blooming or compatibility issues with cross-linkers.
For formulators developing specific systems, detailed technical data is essential. You can review the UV Absorber UV-5151 formulation guide wood coatings 2026 to understand upcoming regulatory shifts and performance expectations. Additionally, those seeking direct performance comparisons should consult the UV Absorber UV-5151 Tinuvin 5151 equivalent for wood coatings analysis for synthesis and specification details. Proper integration during the let-down phase of production ensures optimal stability without interfering with catalyst systems.
UV-5151 Procurement Guide: Supply Stability and Regulatory Compliance
Securing a reliable supply of UV-5151 requires vetting manufacturers based on quality assurance protocols rather than regulatory claims alone. Procurement teams should prioritize suppliers who provide comprehensive documentation, including Certificates of Analysis (COA), Material Safety Data Sheets (MSDS), and GC-MS chromatograms. These documents verify purity, identity, and safety handling requirements without relying on unverified compliance assertions.
NINGBO INNO PHARMCHEM CO.,LTD. maintains strict quality control measures to ensure every batch meets industrial purity standards. Supply stability is supported by robust inventory management and production planning, ensuring consistent availability for bulk orders. When evaluating potential partners, request sample batches for internal testing to confirm compatibility with your specific resin systems before committing to large volumes.
