History of the development of color coating production lines and pre-coating processes

1. The origins of technology (1930s)

1935: The United States built a continuous pre-coated coil production line, using alkyd resin paint to paint steel strips, with a line speed of 12m/min. It took about 12 hours to produce 1 ton of steel coils.

Application: Used to make blind panels and windproof walls, replacing wooden products.

2. Technological development (1970s)

Background: With the development of the construction industry, color-coated steel plates have begun to be widely used in building envelope systems.

Features: Modern color coating technology has developed into a continuous production line integrating pretreatment, coating and baking.

3. Technological maturity (1980s)

Background: Pre-coating technology originated in the 1980s and has been widely used in Europe and the United States.

Features: Pre-coating film is a process in which plastic film is pre-coated with adhesive, rewound, and then hot-pressed and combined with paper printed products.

4. Technology enters Asia (1996)

Background: In 1996, pre-coating technology entered the Asian market.

Application: In 1999, Guangdong Yike New Materials Co., Ltd. began to enter the research and development field of composite pre-coated films.

5. Current technological situation (21st century)

Background: In 2021, the pre-coated film market size was approximately 1.468 billion yuan, a year-on-year increase of 26.55%.

Features: Pre-coating technology has been widely used and has become an important post-press coating technology.

6. Technological Future

Trend: With the advancement of environmental protection work, the market for pre-coated films in China continues to grow, and there will be more application areas and market space in the future
