Henkel has warned that new EU legislation on glymo could have a significant impact on the packaging industry, after the company developed a test method to detect epoxy silane and its degradation materials. The German company said it had developed a legislative framework to regulate the use of epoxy silanes based on their genotoxic potential, thereby increasing the demand for "suitable alternatives". FEICA, the European Association of adhesives and sealants industries, has recommended avoiding the use of epoxy silanes in food contact applications. The EU is expected to set new limits by September at the latest. Henkel said the company's new tests involved a combination of "several complex analytical techniques" to detect epoxicidal silanes such as glymo and glyeo and their degradation products. Last December, the company launched a series of composite adhesives without epoxy silane. Loctite lioflol La 2798 is a modular system designed for high temperature food contact and medical applications. In various applications, it was found that epoxy silane increased the adhesion between aluminum and polyolefin films, and maintained the adhesion even at high temperature. After studying the existing toxicology data, the European food safety agency concluded in 2017 that glymo must be considered to be potentially genotoxic. Dr. Andr é Weiss, manager of the instrument analysis department of Henkel food safety project management, said that in the future, as long as it can be proved that it will not harm human health, glymo as an adhesion promoter will still be allowed to be used. Weiss explained that products containing epoxy silane are not allowed to be used as fat fillers and that epoxy silane should not be detected in water-based fillers. He added: "however, the key point is that processors and packaging manufacturers need to provide evidence that there are no structurally similar chemicals such as glymo and glyeo. This means there are two factors - the right adhesive and the right test method to prove it. " Loctite lioflol La 2798 can be combined with a variety of hardeners to reduce the complexity of the processor. Henkel currently offers four hardeners. Two are aromatic curing agents for boiling and pasteurization, which are said to be suitable for animal food or hot filled products. The third one is aliphatic hardener for general distillation, which solidifies at room temperature. It is recommended to sterilize it for 45 minutes at 134 ℃ to make it suitable for infant food. The fourth hardener is specially used for liquid packaging and disinfection, especially for high-fat food and oily food with high fat content, such as cat food.
