Universal high strength anaerobic adhesive. Due to its high adhesion and strength (25 Nm torque at pull-off) and high viscosity, adhesive 6638 is designed for the assembly and fixing of loose-fitting elements. After curing, it forms a strong sealant/adhesive layer that is resistant to chemicals, dynamic loads and vibration. In addition, it prevents corrosion and distributes stress across the entire joint surface, increasing the reliability and durability of the bonded element.
Anaerobic adhesive 6638 can be used to permanently bond screwed joints (including M35). Dismantling of joints, if required, is carried out by pneumatic tools / part heating. Apply the adhesive to the surface/joint and allow to cure.
