Powder coatings, with their environmentally friendly and efficient advantages, are increasingly becoming the preferred surface treatment solution in high-end manufacturing. As market demands for coating effects and product surface performance continue to rise—whether it's addressing long-term protection in extreme corrosive environments or meeting durability challenges in demanding operating conditions—each technological breakthrough is rooted in a precise understanding of the material's molecular structure and thermal behavior.

Today, we sincerely invite you to visit Qianjiang High-tech Powder Coating R&D Center to experience the technological charm of three internationally advanced analytical instruments - FT-IR infrared spectrometer, TGA thermogravimetric analyzer, and DSC differential scanning calorimeter, and witness how they inject strong kinetic energy into green coating solutions!

Thermo Fisher Scientific FT-IR Spectrometer: Molecular-level "Fingerprint Recognition" Accurately Analyzes the Nature of Materials

Accurate analysis of raw material composition is the cornerstone of powder coating quality control and the primary prerequisite for optimizing formulations and improving performance.

Thermo Fisher Scientific's FT-IR spectrometer, with its high resolution and sensitivity, has become the "gold standard" for R&D teams to analyze the molecular structure of materials. By detecting the infrared spectrum absorbed or emitted by a sample, the instrument can rapidly identify unknown materials, confirm the purity of raw materials, and even detect changes in the molecular structure of trace additives.

Application Scenario：

• Raw material verification:

In powder coating production, minute compositional variations in raw materials like resins, curing agents, and pigments can directly impact the coating's weather resistance, adhesion, and other properties. FT-IR can detect variations in raw material batches in real time, ensuring that each batch of coating meets stringent standards.

• Failure analysis:

When coatings corrode or age in extreme environments, FT-IR can locate the cause of failure through spectral comparison.

• Innovation and R&D:

When developing new functional coatings (such as self-cleaning and antibacterial coatings), FT-IR can track how functional molecules bind to the substrate, providing data support for formulation optimization.

Switzerland/Mettler Toledo TGA Thermogravimetric Analyzer: Unveiling the "Quality Detective" of Material Thermal Stability

The thermal stability of powder coatings has a crucial impact on their processing performance and service life. This is especially true in high-temperature applications such as power batteries and energy storage devices, where high-temperature resistance is directly related to the coating's reliability and durability. With its sub-microgram resolution, the Mettler Toledo TGA thermogravimetric analyzer can monitor sample mass changes in real time during heating, cooling, or constant temperature processes, comprehensively analyzing the material's thermal decomposition behavior, oxidative stability, and adsorption properties, providing critical data support for the design of coatings' thermal stability and weatherability.

Application Scenario：

• Thermal stability authoritative report:

Accurately measuring the decomposition temperature of each component in powder coatings provides core data support for our development of special functional coatings such as high temperature resistant, insulating and flame retardant.

• Corrosion protection studies:

To address the corrosion challenges of energy storage containers in the heavy salt and humidity environment at the seaside, TGA analyzed the mass loss curve of the coating under salt spray and humid heat conditions, optimized the anti-corrosion formula, and extended the equipment service life to 30 years.

• Process optimization:

In the development of low-temperature curing powder coatings, TGA can measure the volatile content of the coating under a 160°C/10-minute curing process, helping to adjust the resin-to-curing agent ratio and achieve a 30% reduction in energy consumption while maintaining stable performance.

Switzerland/Mettler Toledo DSC Differential Scanning Calorimeter: A "microscope" for energy changes, quantifying material thermal effects

‍

Thermal parameters of powder coatings, such as the glass transition temperature and crystallization behavior, are crucial for determining their processing performance and final application results. Mettler Toledo's DSC differential scanning calorimeter accurately quantifies thermal effects such as melting, crystallization, and glass transition by measuring the difference in heat flow between a sample and a reference material during temperature changes.

DSC Differential Scanning Calorimeter

Application Scenario：

• Recipe design:

When developing high-performance powder coatings for various harsh application scenarios, DSC can measure the glass transition temperature of the coating from -30°C to 500°C, ensuring that the coating does not crack in cold areas and does not soften in high temperature environments.

• Process control:

During the curing process of powder coatings, DSC determines the optimal curing temperature and time by monitoring the heat flow curve, avoiding the loss of adhesion due to insufficient curing or the embrittlement of the coating caused by over-curing.

• Failure prevention:

For the insulating coating of energy storage battery PACK components, DSC can analyze the thermal aging behavior of the coating during long-term use, predict its service life, and provide a scientific basis for product quality assurance.
