Aluminum silver paste is a kind of pigment. It has undergone special processing technology and surface treatment to make the surface of the aluminum sheet smooth and flat, with neat edges, regular shapes, concentrated particle size distribution, and excellent matching with the coating system. In industrially developed countries, aluminum-silver paste is the largest category of consumption. In the first half of 2012, the consumption of aluminum-silver paste has exceeded more than half of the total consumption of aluminum-silver paste. The main production countries of aluminum silver paste are the United States, Germany, Japan, the United Kingdom and China. The aluminum silver paste industry started in China in 1995. At that time, the first aluminum silver paste company to enter the market was the German company ECKART. Then TOYO and SILBERLINE also entered the Chinese market one after another. The German, American and Japanese aluminum-silver pastes represented by them are different: some aluminum-silver paste products are suitable for intermediate coating automotive coatings.

 At present, the domestic demand for medium and high-end aluminum paste market is 15,000 tons, of which about 2,500 tons are imported from abroad. The medium and low-end aluminum silver paste market is basically occupied by domestic manufacturers, especially the low-end aluminum silver paste market. In the high-end aluminum and silver paste market, Chinese companies and foreign companies are very different. With the development of the market, the quality and stability of domestic aluminum silver paste products continue to improve, which has gradually reduced the sales of some well-known manufacturers such as ECKART and SCHLENK in the Chinese market. The prices of their mainstream products in the Chinese market have also been forced to reduce year by year. Among them, from January to June 2012, the global demand for aluminum silver paste will increase at an average annual rate of 3.1%. The growth rate of industrialized countries with more mature markets is slower, and the demand for aluminum and silver paste in North America and Western Europe will increase by 2.1% each year. Will continue to account for more than half of global demand. Japan is even lower, with an average annual increase of 1.9%, but reversed the negative growth of 1.3% annually from 2011 to 2012. In addition, the growth of demand for aluminum and silver paste in developing countries will be higher than the world average. China will grow at a rate of 7.6% each year and is the largest aluminum silver paste market in Asia. The average annual growth rate in India will also be 7.5%.

 China's aluminum and silver paste production industry started in the early 1990s, and its production history is relatively short compared with foreign companies. Companies that started relatively early include Zhangqiu Metal Pigment Co., Ltd., Jinan Yasida Chemical Technology Development Co., Ltd., Danyang Guangyang Aluminum and Silver Powder Factory, Shenzhen Zuxing Industrial Co., Ltd. and so on. They all started with imitating Aika aluminum silver paste. After that, because of Zuxing's imitation technology, some skilled workers have flowed out of Zuxing. Many aluminum and silver paste manufacturers have been established by using Zuxing's technology, such as Shanghai Shanjing Aluminum Industry Development Co., Ltd., Dongliang Aluminum Industry Co., Ltd., etc. After several years of development, each enterprise has gradually developed and grown, forming a situation where each has its own characteristic products. At present, Zhangqiu’s production capacity is relatively large, with an annual output of about 8,000 tons; Zuxing’s annual production capacity can reach 3,000 tons; the annual production capacity of Yasida and Dongliang is about 2,000 tons each, and the production capacity of other manufacturers is relatively small. .

Through in-depth understanding of the status quo of domestic enterprises, domestic aluminum and silver paste enterprises have deficiencies in R&D, raw material selection, production process control, after-sales and technical support.

1. Domestic companies tend to focus on aluminum and silver paste production and sales. Very few dedicated teams study the market, competitors, and especially downstream applications. Most aluminum-silver paste plants basically have no knowledge of the specific application status of downstream customers.

2. The aluminum-silver paste industry is basically in a semi-closed state, with no inter-industry exchanges. Some large factories divide their technical personnel into several parts and each is responsible for only a certain part; they rarely use the power of scientific research institutions to systematically develop new products.

3. Regarding the selection of raw materials: Among the large aluminum and silver paste companies, the author only saw Zhangqiu starting from spray aluminu
