Sealant is commonly used in construction, automotive, electronics and aerospace industries to fill and seal joints, waterproof, insulation and shock absorption. However, sealant may suffer from aging, degradation and performance degradation under long-term exposure to environmental factors such as ultraviolet light, temperature and humidity.

Ultraviolet aging test chamber can simulate the ultraviolet radiation and climate conditions in the real environment, by accelerating the aging process of sealant, performance evaluation.

Test procedure
The following is the specific process of UV aging test chamber in the application of sealant:

Select the sealant material that meets the requirements. According to different application requirements, choose the appropriate type of sealant, such as silicone sealant, acrylic sealant, etc.

According to the test requirements, determine the ultraviolet radiation source, temperature, humidity and radiation time parameters in the test chamber. These conditions should be able to simulate real UV radiation and climatic conditions such as sunlight exposure, high temperature, humidity, etc.

The sealant sample is coated on a specific sample substrate, or the sealant sample is filled in a sample simulating a joint. After ensuring that the sample is completely dry, place it on the sample table in the test chamber.

Start the UV aging chamber and expose the sample to simulated UV radiation. According to the set test conditions, radiation for a certain time. At the same time, the hot and humid cycle can be selectively carried out to simulate the real environmental conditions.

Periodically monitor and record the performance changes of sealant samples. You can use appropriate instruments and equipment, such as tensile testing machines, viscometers, etc., to measure and record the tensile strength, viscosity, hardness and other indicators of sealant.

According to the test data and evaluation index, the aging degree and performance changes of sealant samples were analyzed. Compare the differences between different test samples to evaluate the durability, stability and service life of the sealant.

Testing through the UV aging test chamber can provide a reliability assessment of sealant materials, guide manufacturers and users to select the appropriate sealant, and ensure its durability and performance requirements in various application fields. This helps to provide a high quality and reliable seal, ensuring the reliability and durability of joints and seals.

Industry standard
In the ultraviolet aging test of sealant, the following industry standards can be referred to:

ASTM C1442 is a standard published by the American Society for Materials and Testing (ASTM) for the testing of film protective coatings, including film coatings of sealants. This standard provides some guidance for coating performance tests which can be applied to the performance evaluation of sealants.

ISO 6927 is a standard published by the International Organization for Standardization (ISO) for determining the change in mass and volume of sealants after immersion in liquid chemicals. This standard can be used to assess the durability of sealants in different chemical environments.
