Tongli Technology’s TPU/TPH/TPE automotive paint protection film has successfully passed 1000-hour tests with a comprehensive rating of Grade 0 under four major standards:
- SAE (Society of Automotive Engineers) "Accelerated Exposure Test for Automotive Exterior Materials"
- GB/T 1865-2009 "Artificial Climate Aging Test"
- GB/T 1771-2007 "Test Method for Salt Spray Resistance of Coatings"
- GB/T 1740-2007 "Test Method for Damp Heat Resistance of Paint Films"
Originating in the United States, paint protection film was first applied to metal components of aircraft and wind turbine blades to protect coatings. Around 2008, it entered China as a new concept in automotive beauty, ushering in a decade of growth. However, due to immature materials and technologies, coupled with high industry barriers, the localization of paint protection film in China has encountered a series of problems, causing significant losses to distributors and consumers. The market is flooded with products of varying quality, lacking unified standards and featuring a mix of reputable and shoddy brands.
Current Key Issues of Paint Protection Films in the Market:
- Failure to meet aging test requirements, leading to product discoloration and yellowing.
- Non-compliance with salt spray, acid and alkali resistance tests, resulting in coating fogging, rain spots and loss of luster.
- Inadequate damp heat resistance, causing film blistering and cracking.
- Poor adhesive compatibility, leading to adhesive failure and residue.
Tongli Technology has dedicated extensive efforts to addressing these issues. With R&D centers in South Korea and production & testing facilities in China, the company has made breakthroughs by adhering to high-quality materials—including Japanese thermosetting polyurethane coatings and Henkel-series pressure-sensitive adhesives—to enhance product performance. Targeting the aforementioned problems, Tongli submitted its products for all relevant tests and passed them all in one go.
Product development requires continuous improvement and refinement. Tongli Technology will continue to invest human and material resources in paint protection film research, ensuring every vehicle can be equipped with high-quality, cost-effective protection. Our philosophy: Let car film return to its essence—an extra layer of transparent protection for the original paint. We are committed to creating durable products, focusing on substance over gimmicks, and staying true to product fundamentals.
