VISIOMER® - Methacrylates for HIGH-PERFORMANCE ADHESIVES AND SEALANTS
VISIOMER® specialty methacrylates are used in reactive 2 component adhesive and sealant formulations. Most popular are anaerobic or structural adhesivees, based on methacrylates. Emulsion polymers for pressure-sensitive adhesives and sealants also contain our VISIOMER®.
Structural acrylic adhesives are used in the transportation industry for OEM assembly and in marine applications. For structural methacrylic adhesives, the choice of monomers largely depends on the substrate to be bonded. Usually, no surface preparation is needed for this type of reactive adhesives – one of the major advantages of methacrylic-based adhesives
Anaerobic acrylic adhesives are well known for their superior properties in fixing and sealing metal joints, for example.
Methacrylate monomers are used as comonomers mainly in binders for water-based PSAs, but also for acrylic hot melt systems. They are added to improve mechanical properties and provide additional functionalities like adhesion promotion. Acrylic PSAs are mainly used as adhesives for labels, tapes or lamination, especially in the packaging industry.
VISIOMER® IBOMA, BNMA, THFMA and EHMA are used in combination with VISIOMER® Crosslinkers for the formulation of structural adhesivees.
VISIOMER® MEEU is used to improve adhesion and cohesion of emulsion polymers for PSA´s
• Enhanced cohesive strength and resistance
• Fomulation components with low hazard potential
• Increased adhesion to polar substrates
