Evonik Supplies Methacrylate Phosphate as Anti-corrosion Agent, Flame Retardant
Evonik plans to market 2-hydroxyethyl methacrylate phosphate as an anti-corrosion agent and flame retardant under the brand name VISIOMER HEMA-P 70M. Typical product applications of this methacrylate monomer include adhesives and plastics, paints and coatings, fibers, composite resins, and gel coats.
Customers mainly use VISIOMER HEMA-P 70M as an adhesion promoter, but the latest findings have also shown it to be an effective halogen-free, reactive flame retardant or anti-corrosion agent. Since the substance serves as a reactive diluent or as a co-monomer bonded within the polymer backbone, it does not migrate like conventional flame retardants. VISIOMER HEMA-P 70M further improves flame retardancy in combination with non-polymerizable flame retardants.
“VISIOMER HEMA-P 70M offers new options for customers with special requirements for flame-retardant and anti-corrosion properties. This monomer adds a specialty methacrylate with particular functionalities to Evonik’s portfolio and underscores our role as a solution provider for innovative customers,” said Dr. Martin Trocha, the head of Evonik’s Application Monomers Product Line.
VISIOMER HEMA-P 70M is a highly versatile monomer that contains 30 percent methyl methacrylate and is particularly easy to process because of its low viscosity. Thanks to its low color index, the specialty monomer is particularly well-suited for optical applications in acrylate and methacrylate systems. This enables the use in applications with high demands for transparency and surface quality, such as surface coatings, plastics or adhesives.
Moreover, the monomer protects against static charging and has an emulsion stabilizing effect.
