Permabond TA04820K050C1607

TA4820 Two-Part Toughened Acrylic Adhesive, Cream, 50ml Cartridge

(Case of 12)

Permabond® TA4820 is a two-part, 1:1 toughened methacrylate adhesive designed for bonding thermoplastics, thermosets, metals, and composites. TA4820 has excellent adhesion to received metal surfaces, forming high-strength bonds without surface preparation. It provides exceptional durability and resistance to common industrial solvents and fuels and harsh environmental conditions. It cures rapidly at room temperature and its thixotropic properties allow for easy dispensing through static mixing nozzles while maintaining good gap-filling and non-sag properties. The long fixture time allows for the accurate alignment of larger components.

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