"Super glue" keeps the paint from peeling off

Coatings Raw Materials and Equipment Network:
Many of the products we use every day are glued together by adhesives, and researchers hope a newly developed "super glue" formula will make everything from protective clothing, medical implants and residential pipes stronger and more resistant to corrosion.“ Imagine that paint never peels off, waterproof paint never needs to be resealed... This is what many chemists and composite engineers seek. The researchers said.crosslinking: When the adhesive is exposed to high temperatures or long waves of ultraviolet light, this crosslink occurs, forming a strong connection that is both impact-resistant and corrosion-resistant. Even if the amount of crosslinking is small, these materials are still tightly integrated.Super Gluehas discovered ways to make new "super glues According to media reports, a team of chemists and synthetic materials researchers from the University of British Columbia's Okanagan campus and the University of Victoria have discovered a way to create a new "super glue" that connects plastics to synthetic fibers at the molecular level, creating strong connections that are both impact-resistant and corrosion-resistant. The study was recently published in the journal Science.the method of making this "super glue" is called crosslinking, and jeremy Wolfe, a professor of organic chemistry at the University of Victoria, led the design of the new crosslinking material. It is reported that when the adhesive is exposed to high temperature or long-wave ultraviolet light, this crosslink will act, thus forming a strong connection that is both impact-resistant and corrosion-resistant. Even if the amount of crosslinking is small, these materials are still tightly integrated.researchers report that they have "reasonablely" created a double-gin molecule that can be broken down into carbines (also known as carbonene) when exposed to heat or light. "Reasonable" means that the researchers balanced the risk of explosion or fire, providing the best results, i.e. a molecule can be inserted into a hydrocarbon polymer bond. The report states that this double gin molecule is capable of interlinking various polymer chains, including polyethylene and polypropylene, and that when used with polypropylene, the increase in molecular weight is directly in directly in direct association with the amount of crosslinkers used.crosslinkers provide additional material strength for fabrics the researchers also looked at the possibility of using crosslinkers in high-density polyethylene. "This adhesive has proven to be particularly effective in high-density polyethylene, an important plastic for bottles, pipes, earthfilms, plastic wood and many other applications." Professor Mirani, director of the Institute of Materials and Manufacturing at the University of British Columbia and lead researcher of the Composites Research Network, who was involved in the study, said: "The glue available on the market today doesn't work at all on these materials. Wolfe team worked with the Centre for Survival and Development Applied Research at the University of Victoria to explore the performance of the material in practical applications, one of which was a high-performance body jacket. "By using crosslinking technology, we are better able to combine different levels of fabric types to create the next generation of clothing for extreme environments." "At the same time, crosslinkers provide additional material strength for the fabric itself," Wolff said.is just the tip of the iceberg for the potential use of this adhesive technology, says Mr. Mirani, "imagine that the paint never peels off and the waterproof paint never needs to be resealed." We're even starting to think about it as a way to glue many different types of plastics together, which is a major difficulty in recycling plastics and their composites. Making some of our everyday items stronger and less prone to failure is what many chemists and composite engineers seek.
