Scotch-Weld Pipe Sealant PS77

February 2010

Additional Product

Information

Anaerobic adhesives only cure in the absence of air and with metal part activation.

Adhesive outside the joint will remain uncured and may be wiped away with a cloth.

PS77 is suitable for most straight and tapered pipe threads of medium to coarse

pitch, for pipe diameters from 15mm to 80mm. PS77 will not cure outside the joint

and is virtually non-fouling in most types of pipe systems. PS77 is not

recommended on certain plastics as stress cracking can sometimes result. Some

anti-corrosion chemicals inhibit the cure system in this type of anaerobic. Trials are

recommended to establish whether cleaning of the parts in necessary.

AC64 Activator may be required on plated parts.

Application

Techniques

Ensure parts are clean, dry and free from oil and grease.

Apply adhesive to all engaged threads, although to minimise excess adhesive

inside the joint, apply adhesive only to the male part, leaving the first two threads

clear. Assemble parts and allow to cure. Wipe excess adhesive from outside of

joint.

Heating the assembled parts accelerates the curing process.

AC64 Activator may be used to accelerate cure and should be used if the

application temperature is below 5ºC. The use of an accelerator may reduce the

final bond strength by up to 30%

Storage Conditions

Keep the adhesive in a cool, dry place away from direct sunlight. Under such

conditions shelf life at room temperature will be 12 months.

Refrigeration to 5◦C gives optimum storage stability.

Shelf Life

12 months from date of despatch by 3M when stored in the original carton at 21°C
