The inscription of Tan Zhuzhou, former president of the China Petroleum and Chemical Industry Association, for Shanghai Kailin Paint Factory is 'Pioneering Chinese Coatings, Establishing the Forest of World Coatings'.

Shanghai is the birthplace of Chinese coatings. Kailin Paint Factory (meaning the development of primitive forests) was founded in 1915 by Mr. Ruan Ainan and Mr. Zhou Yuantai in Baoshan Road, Shanghai, producing thick white paint and white lead powder. In the course of a hundred years of historical development, 'Huayi Refinement' has embraced all rivers, gathered essence and bred many excellent paint brands. 'Kwang Ming' is one of the bright pearls.

The birth of the 'Kwang Ming' card can be traced back to the 1950s. At that time, Kailin Factory had 12 small businesses merged, bringing together trademarks such as 'Double Axe', 'Great Wall', and 'Kwang Ming'. At a time when the country had not yet been liberated and the prospects of the motherland were bright, the paint used for object protection and decoration always gave people a fresh and beautiful feeling. Therefore, Kailin Factory decided to use the 'Kwang Ming' brand as the company's product trademark and officially submitted a registration application to the Shanghai Administration for Industry and Commerce, with the number '5587'. At that time, the entire pattern was a long torch, with the sun as the background. The torch handle had a flowing red ribbon, and symmetrical pentagrams and wheat ears on both sides. Starting from the Second Five Year Plan of our country, the state vigorously promoted the power of the working class, especially the industrial education of Daqing, which was the main theme of the times at that time. So, Kailin Factory made modifications to the 'Kwang Ming' trademark pattern, removing the background pattern and the five pointed star and wheat ear next to it, and adding an arm that tightly holds the torch, thick and powerful, giving people a feeling of 'we workers have strength' at first glance. This trademark is still in use today.

Nowadays, Kailin Factory has been celebrating its centenary, with over 1000 'Kwang Ming' brand products and a comprehensive range of products from high-end to mid to low-end, including fluorocarbon, polyurethane, epoxy, chlorinated rubber, alkyd, asphalt and other product series. At the same time, it has upgraded from a single product production to a supporting model of 'product+service' to meet the diverse needs of customers.

Over the years, 'Kwang Ming' brand products have won a series of titles such as the National Science and Technology Award and the Military Industry Award. They have developed supporting coatings for many major domestic projects, including the Xiangyanghong Scientific Research Ship, Qinshan Nuclear Power Plant, Three Gorges Project, Lupu Bridge, Pudong International Airport Phase I and II, Yangtze River Tunnel Bridge, National Convention and Exhibition Center, and Pudong Airport Satellite Hall, and have received high praise from users. The 'Kwang Ming' brand paint not only paints colors, but also witnesses the bright future of our country's prosperity.
