Permabond TA4820 Structural Acrylic Adhesive
Categories: Polymer; Adhesive; Thermoset; Acrylic/Cyanoacrylate Adhesive

Material Notes: PERMABOND TA4820 is a 2-part, 1:1 toughened methacrylate adhesive designed for bonding thermoplastics, thermosets, metals and composites.  TA4820 has excellent adhesion to as received metal surfaces forming high strength bonds without surface preparation. It provides excellent durability and resistance to many common industrial solvents, fuels as well as environmental conditions. It cures rapidly at room temperature and has very good thixotropic properties allowing for easy dispensing through static mixers while maintaining good gap filling and non-sag properties. The long fixture time allows for accurate alignment of large components.

Features & Benefits:

  • Adhesion to a wide variety of substrates
  • Fast cure at room temperature
  • High shear and peel strength
  • Good impact strength
  • Good chemical resistance
