On October 23, CTC held a signing ceremony with German company Linseis for "Joint Development and Application of Coating Material Thermal Expansion Meter and Coating Residual Stress Tester." Qin Xianming, Deputy General Manager of CTC; Bao Yiwang, Chief Scientist; Wan Detian, Executive Deputy President of the Central Research Institute; Xie Jinli, Executive Deputy President of the Refractory Products Inspection and Certification Institute; Vincent Linseis, Chief Technology Officer of Linseis; Liu Zhong, General Manager of Linseis (Shanghai) Scientific Instruments Co., Ltd.; and Li Hang, Supervisor, attended the signing ceremony. Wan Detian chaired the signing ceremony.

The technical foundation of this cooperation originates from the international patent PCT/CN 2016/074483 applied for under the Patent Cooperation Treaty by Bao Yiwang's team at CTC, which has been granted by the United States Patent and Trademark Office (Patent No. US 10222343). At the same time, based on this technology, the international standard ISO DIS 23458 "Test method for determining thermal expansion coefficient and residual stress of CVD ceramic coatings" was formulated.

Qin Xianming introduced in detail CTC's advantages and strong comprehensive strength in the inspection and certification service field. Qin Xianming emphasized that this cooperation demonstrates the trust and recognition of CTC's professional technical capabilities by international partners such as Linseis, and is of great significance for advancing the Group's international business. Vincent Linseis introduced that Linseis is a world-renowned analytical instrument enterprise that has established a long-standing cooperative relationship with China. This time, it has obtained the exclusive international patent license for CTC's coating material thermal expansion meter and coating residual stress tester, and will jointly develop and globally promote them. The cooperation between the two sides can achieve complementary advantages, which is conducive to promoting the application of coating thermal expansion coefficient and residual stress testing technology worldwide, and can also increase the functional application scope of Linseis instruments and enhance competitiveness in the field of coating material thermophysical property testing.

Bao Yiwang and Vincent Linseis signed the cooperation agreement on "Joint Development and Application of Coating Material Thermal Expansion Meter and Coating Residual Stress Tester" on behalf of the Chinese and German sides, respectively. This signing marks the beginning of cooperation between the two sides. CTC will make full use of this cooperation to actively promote the application of its independently developed coating patented technology at home and abroad, and continuously enhance CTC's core competitiveness and international influence.

During the visit, Vincent Linseis and his delegation also visited the State Key Laboratory of Green Building Materials and delivered a thematic report titled "Testing of Thermophysical and Thermoelectric Properties of Bulk and Thin Film Materials," focusing on the development history of Linseis and the company's main testing instruments for thermophysical property testing.
