Adhesives are more common in our life, and can not be ignored in life. What kinds of adhesives are there? Let’s take a look. Polyacrylic resin: Mainly used in the production of pressure-sensitive adhesives, but also used in textile and construction fields. In recent years, domestic enterprises from abroad introduced several pressure-sensitive adhesive product production […]
The weakness of ordinary water-based acrylate PSA is poor bonding strength and heat resistance, and it is difficult to firmly bond on low surface energy materials. The molecular structure of organosilicon contains Si-O-Si bond and side chain organic groups, and its molecular chain is highly curly, the intermolecular association is small and the intermolecular attraction […]
The adhesion of PSA is mainly due to the van der Waals force and hydrogen bond formed between PSA and the surface of the bonded substrate. The surface of the bonded substrate has a complete structure and partial electron rearrangement. Aqueous acrylate emulsion has good surface wettability, so the adhesion and initial adhesion of corresponding […]
Acrylate PSA mainly includes a solvent, water-based acrylate PSA two categories: solvent acrylate PSA VOC(volatile organic matter) content is larger, and its in the environment, resources, and safety. There are many drawbacks, so the scope of its use is limited. The water-based acrylate PSA uses water as a solvent, which has the characteristics of environmental […]
Green environmental protection is the theme of current industrial production, and countries all over the world pay more and more attention to the sustainable development of the environment and energy. Although the shortcomings of organic solvents, such as toxicity, inflammability, and pollution, lead to the development and application of solvent-based acrylate pressure-sensitive adhesives being limited, […]
