Exhibition Review | Q-Lab Debuts at Powder Coatings and Coating Industry Exhibition with Zhanlin Instrument

On November 3rd, the 2025 Powder Coatings and Coating Industry Exhibition was grandly opened in Wuhan, Hubei. The exhibition covers an area of approximately 10500 square meters, with nearly 200 domestic and foreign powder coating raw material and equipment companies showcasing on site. On the first day, it attracted over 8000 professional visitors to attend and exchange ideas.

This time, Zhanlin Instrument, as the agent of Q-Lab in the Chinese coating industry, participated in the conference with Q-Lab to share the application of accelerated aging and corrosion testing equipment in the durability evaluation of powder coatings, helping enterprises to support product research and quality control with more reliable data.

New benchmark for large capacity rotating xenon lamp aging platform

At this exhibition, almost all discussions about the "outdoor realistic reproduction" of powder coatings will point to the latest generation Q-SUN Xe-8 xenon lamp test chamber: many visitors stayed in front of our booth for the longest time and asked the most questions, which also revolved aroundFull spectrum xenon lamp, rotating large capacity, and temperature/humidity/spray linkage cycleThese three things.

What everyone is most concerned about is the three questions - can you press themASTM/Does ISO do it? How many can you run at once? Can it run continuously 24/7 and produce results as soon as possible? These are precisely the strengths of the Q-SUN Xe-8.

Efficient verification:

The Q-SUN Xe-8 uses a full spectrum xenon lamp, temperature/humidity, and front and rear spray control to reproduce service conditions such as "sun exposure rain dry wet cycle"; Supports three irradiance control points of 340nm/420nm/TUV (300-400nm) and multiple filter combinations, aligning with mainstream industry/vehicle standard methods (such as ASTM G155, ISO 16474-2, etc.).

Large capacity, low cost:

The rotating sample holder can hold 164 pieces (2 × 4 inches) or 96 pieces (2.6 × 5.7 inches), four 4200WXenon arc lamp24/7 continuous operation significantly shortens the verification cycle compared to outdoor exposure, while balancing operation and lamp cost.

Easy to use and robust:

Blackboard/black label and box temperature coordinated control, relative humidity closed-loop, programmable front/rear spray; AUTOCAL ®/ SOLAR EYE ® Convenient calibration and light control, daily maintenance can be completed from the front/top of the device, making it easier to get started and maintain.

Building facade/aluminum profile (outdoor exposure)

This type of scenario first focuses on the "visible persistence" - whether the color deviates, whether the gloss collapses, and whether the surface is powdery. Use Q-SUN Xe-8 to select a filter that is close to sunlight, set stable lighting and temperature and humidity, and then intersperse short-term spraying to simulate the rhythm of "sun exposure rain re exposure".

Home appliances/coil components (outdoor/semi exposed)

White battery casings, outdoor casings, and roll powder parts often balance appearance with mild environmental stress. The application method is very direct: first, the color, gloss, and pulverization are run through on the Q-SUN Xe-8, and then salt spray or cyclic corrosion is added to supplement the corrosion resistance verification of edges, cuts, and other positions according to the product risk, restoring the superposition effect of "sun+moisture" in real use.

Municipal/outdoor facilities (exposed to sunlight+repeated rain)

The biggest daily challenge for components such as guardrails, lamp posts, and seats is the repeated switching between "sun exposure and high temperature" and "sudden rainfall". The programmable front/rear spray of Xe-8, combined with relative humidity control, is precisely capable of bringing this kind of hot cold humidity conversion into the laboratory. It is recommended to observe color difference, gloss, and powdering simultaneously on the same batch of samples.

The success or failure of powder coating ultimately depends on the real working conditions of sun exposure, humidity, and rain. The Q-SUN Xe-8 uses a full spectrum xenon lamp combined with temperature/humidity/spray linkage and rotating large capacity to efficiently concentrate these scenarios into the laboratory - faster exposure failure, compression verification cycle, and smooth integration with international standards such as ASTM G155.
