In modern industry, coatings serve not only aesthetic purposes but also crucial functional roles, such as corrosion resistance, UV stability, temperature endurance, and waterproofing. To ensure these properties meet international standards and customer expectations, accelerated environmental testing is essential.
LIB has developed a comprehensive test chambers that simulate real-world conditions, enabling precise evaluation of coating durability and long-term performance.
Stable and Standardized Salt Spray Chambers for Corrosion Testing
1. Basic Salt Spray Test Chamber
LIB's Basic Salt Spray Test Chamber delivers reliable and efficient corrosion testing under controlled salt spray environments. In accordance with ASTM B117 and ISO 9227, the system sprays a 5% NaCl solution using a high-precision quartz nozzle at 83 kPa, supported by a 30L built-in salt tank with an automatic heating and stirring system. A saturated air barrel preheats air to ensure fog consistency at 35°C ±2°C, while salt deposition is monitored at 1–2 ml/80cm²·h. The inner chamber is made of FRP with an inverted lid design to prevent dripping, ideal for testing corrosion-resistant coatings on automotive, marine, and metal components.
2. Cyclic Salt Corrosion Test Chamber
LIB's Cyclic Salt Corrosion Test Chamber expands capabilities beyond static salt fog, adding alternating exposure to temperature (10°C~90°C), humidity (30%~98% RH), and dry conditions, complying with ASTM G85, ISO 7253, IEC 60068-2-52. The chamber features dual rear fans, a programmable PLC touchscreen, and multiple test modes including Salt Spray, Dry, and Wet Cycle. The external salt tank with continuous mixing, paired with a circulating water purification system, enables long-term, repeatable corrosion stress simulations for outdoor coating performance.
3. Salt Fog Spray and SO2 Gas Corrosion Test Chamber
To simulate industrial or urban environments, LIB's Salt Fog and SO₂ Gas Chamber introduces controlled SO₂ gas flow into the test space along with salt spray, creating a comprehensive acidic environment. The system includes SO₂ cylinders, flow regulation valves, and an NaOH neutralizing tank for safe gas management. This configuration replicates acid rain and exhaust gas exposure, making it ideal for evaluating coatings on infrastructure, electrical cabinets, and industrial equipment under corrosive gas conditions.
Accurate and Accelerated Weathering Tests for UV and Full-Spectrum Exposure
4. UV Weathering Test Chamber
LIB's UV Weathering Test Chamber utilizes 8 x 40W QUV lamps (UVA-340 or UVB-313) to simulate ultraviolet aging according to ISO 4892-3 and ASTM G154. The system supports up to 90°C chamber temperature and ≥95% RH humidity. Its 10-nozzle water spray system (0.3 L/min) replicates rain under UV radiation, while black panel temperature (BPT) sensors and UV radiometers (340nm, 313nm) ensure accurate irradiance control. With 52 adjustable sample holders (75mm x 150mm), it guarantees uniform UV exposure across multiple coating types.
Xenon Arc Test Chamber
LIB's Xenon Arc Test Chamber simulates full-spectrum sunlight from 280–800nm, powered by a 4500W water-cooled xenon lamp. It meets ISO 16474-2, ASTM G155, SAE J2527 for coating weathering. A rotating sample holder mounts 42 specimens to ensure even light exposure. PID controllers with up to 120 programmable profiles and full-spectrum radiometers (340nm, 420nm) enable traceable light and temperature conditions. Dual water spray systems simulate rain and humidity, with black panel temperature monitoring ensuring realistic thermal stress simulation. This test helps assess coating performance in terms of UV resistance, color stability, and surface cracking under prolonged outdoor exposure.
Comprehensive Temperature and Humidity Testing Chambers
Temperature Humidity Test Chamber
LIB's Temperature Humidity Test Chamber tests thermal expansion, adhesion loss, and moisture-induced degradation in coatings. It simulates harsh climate cycles from -70°C to +150°C and 10–98% RH, with ±0.001°C precision sensors and SUS304 stainless steel interior. Adjustable shelves support 50kg/sample layer. This helps evaluate the coating's flexibility, bond strength, and resistance to blistering under extreme temperature and humidity conditions.
Water Spray Chambers
IPX1, IPX2, IPX3, and IPX4
LIB's IP Water Spray Chambers test coating waterproof performance under IEC 60529. IPX1 and IPX2 simulate vertical dripping; IPX3 and IPX4 use oscillating spray tubes to reproduce rain or splashing from various angles.These tests help evaluate the coating's ability to prevent water penetration, maintain adhesion, and resist blistering or delamination under wet conditions.
From basic corrosion to advanced weathering, LIB test chambers deliver precise, programmable, and standard-compliant testing for all key coating performance indicators-corrosion resistance, UV aging, color stability, temperature durability, and water protection. Built for global standards and real-world needs, LIB ensures coatings are validated before they face the elements.
