NEXO FIX 630 is a general-purpose industrial-grade Cyanoacrylate adhesive with a fast setting, High flow ability, and good penetration characteristics. It has been specially formulated to achieve the strongest possible bond between the well-mated, Non-porous surface. Such as rubber, metal, and plastic. NEXO FIX 603 is a one-component system and does not require the catalyst, Heat, or Clamps. When a thin layer of NEXO FIX 603 is applied between two surfaces and comes in contact with atmospheric moisture, a rapid polymerization occurs producing the ultimate bond.
