specialty methacrylates for better adhesive strength and resistance

Increased adhesive strength and resistance


Reactive acrylics based on methacrylate monomers are used in various adhesive and sealant formulations. Most popular are anaerobic or structural adhesives, based on methacrylates. Emulsion polymers for pressure-sensitive adhesives and sealants also contain VISIOMER® specialty methacrylates.


As their name implies, anaerobic adhesives cure in the absence of oxygen. They are one-component systems that polymerize under the influences of organic hydroperoxides in the presence of metal ions. Owing to the necessary presence of metal ions, anaerobic adhesives and sealants are practically only suitable for bonding and sealing metals. Main application areas are screw locking, fixing, joining and sealing of pipes and flanges. 
Polyethylene glycol dimethacrylates, and especially VISIOMER® TRGDMA and PEG 200 DMA, are the most important group of monomers for manufacturing anaerobic adhesives. 

Pressure sensitive adhesives

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.  VISIOMER® MEEU 25 M and VISIOMER® MEEU 50 W are used to improve adhesion and cohesion of emulsion polymers for PSA's. Acrylic PSAs are mainly used as adhesives for labels, tapes or lamination, especially in the packaging industry.

Metal impregnation

Sintered- or cast metal materials contain faults in the form of crazes or pores, which often require sealing. For this purpose, formulations based on mixtures of mono- and multifunctional (meth)acrylates are used. Long-chain aliphatic acrylates and methacrylates or hydroxyfunctional methacrylates are employed for the monofunctional component, whereas VISIOMER® PEG 200 DMA, VISIOMER® TMPTMA and VISIOMER® 1,4-BDDMA are preferred for the multifunctional component. The impregnation resin containing polymerization initiator is introduced into the metal pores by vacuum or pressure and cured by heat. 

Benefits of specialty methacrylates for adhesives and sealants

  • Enhanced cohesive strength and resistance
  • Fomulation components with low hazard potential
  • Increased adhesion to polar substrates
