SONACME UV accelerated weathering tester uses fluorescent ultraviolet lamps as the light source, and appropriately controls the temperature and humidity to periodically produce condensation on the samples to fully obtain the results of the damage of sunlight, humidity and temperature on polymer materials (material aging) Including fading, loss of gloss, strength reduction, cracking, peeling, chalking and oxidation, etc. The fluorescent ultraviolet rays of the ultraviolet lamp can reproduce the influence of sunlight, and the condensation and water spray system can reproduce the influence of rain and dew. During the entire test cycle, the irradiation energy and temperature are controllable. Typical applications are paint coatings, automotive industry, plastic products, wood products, glue, etc. Standard Test • AATCC TM186: Weather Resistance: UV Light and Moisture Exposure • ASTM C1257: Standard Test Method for Accelerated Weathering of Solvent-Release-Type Sealants • ASTM C1442: Practice for Conducting Tests on Sealants Using Artificial Weathering Apparatus • ASTM C1501: Standard Test Method for Color Stability of Building Construction Sealants as Determined by Laboratory Accelerated Weathering Procedures • ASTM C1519: Standard Test Method for Evaluating Durability of Building Construction Sealants by Laboratory Accelerated Weathering Procedures • ASTM C732: Standard Test Method for Aging Effects of Artificial Weathering on Latex Sealants
