澳客网必发指数 www.3l6n9.com.cn Due to the water-based character of many glues and adhesives and their specific composition they are a suitable media for microbial growth. Uncontrolled microbial growth leads to the destruction of materials that have a negative impact on the environment and may pose health risks for humans. The reduction or the complete elimination of the VOC content of glues and adhesives also increases the need for product preservation.
In industrial applications of glues and adhesives microbiological growth, in particular biofilm formation, can lead to blocking of pipes and nozzles during application. Microbes can also degrade many of the components of glues and adhesives; especially natural substances like starch, casein and natural gums but also synthetic raw materials like polyvinyl acetate are prone to degradation.
For the preservation of glues and adhesives a broad spectrum of activity against bacteria, yeasts and molds is essential. A combination of different biocidal actives represent a cost-effective solution. With parmetol? and grotan? schülke offers for almost every preservation needs an adequate solution.
