Some misunderstandings about glue coating technology

The glue coating process represents a novel technique that has gained significant recognition in China following the widespread adoption of German Vitu Cabinets in recent years. Many businesses and individuals utilizing this process often hold misconceptions regarding its requirements and precautions. This article seeks to clarify several common misunderstandings, hopefully providing valuable insights for those employing this technology. One prevalent misunderstanding about the glue coating process is that it functions similarly to single-sided adhesive foam strips, which are believed to fall off over time. These foam strips are typically adhered via a physical bonding method, relying solely on the adhesive's initial viscosity. This type of bonding, known as physical bonding, can degrade due to environmental changes. For instance, colder temperatures may weaken the adhesive's hold, while heat can reduce its tackiness. Such fluctuations inevitably lead to detachment over time. Conversely, the glue strips produced through the glue coating process achieve chemical bonding. This involves a two-component reaction that results in an irreversible bond, unaffected by environmental conditions. Consequently, the adhesive remains secure regardless of external temperature or prolonged use. Dalian Huagong Innovation Technology Co., Ltd., an early adopter of glue coating technology in China, has extensive experience in this field. The article reflects Mr. Han's personal insights into the technology. He emphasizes pre- and post-sale support, ensuring clients perceive the company's professionalism and reliability. Currently, the company’s equipment has been exported globally, with continuous product innovation. We warmly invite interested parties to reach out for further discussion. Another misconception about the glue coating process is that it applies universally across all materials without consideration. The effectiveness of adhesion depends largely on the surface tension of the workpiece. Materials with high surface tension bond better with the adhesive, creating stronger strips. In contrast, low-tension surfaces, such as certain types of stainless steel or plastic coatings, may yield weaker bonds prone to detachment. To address these issues, two solutions are commonly employed: applying a primer to enhance adhesion or using flame activation techniques to improve bonding on specific surfaces like plastics and fluorocarbon-coated materials. A third misunderstanding concerns the environmental factors affecting the glue coating process. Given its chemical nature, temperature plays a crucial role. Higher temperatures accelerate the reaction, potentially leading to thicker glue strips with larger bubbles, reducing adhesion and causing uneven surfaces. Conversely, low temperatures might hinder the reaction entirely, resulting in brittle or less flexible strips. Similarly, low humidity could contribute to brittleness. Importantly, these outcomes depend on the equipment’s quality being optimal. Finally, there is a misunderstanding that the quality of glue strips depends solely on the equipment rather than the adhesive itself. In reality, both factors are critical. High-quality glue simplifies operations, ensures consistent application, and produces glossy, elastic strips that retain their properties over time. Additionally, it minimizes maintenance and material wastage. Thus, selecting reliable, high-performance glue is highly recommended. In conclusion, understanding the nuances of the glue coating process can significantly enhance its efficacy and reliability. By addressing these common misconceptions, users can optimize their processes and achieve superior results.
