Updated :February 2010 Supersedes : September 2008 Product Description Scotch-Weld PS77 is a single component, medium strength, anaerobic pipe sealant. PS77 is a thixotropic pipe sealant that cures quickly on steel pipes. Scotch-Weld PS77 cures when confined in the absence of air between close-fitting metal surfaces. Key Features Scotch-Weld PS77 is formulated to lock and seal medium to coarse straight and tapered pipe threads on pipes of diameter from 15mm to 80mm. PS77 prevents vibration loosening and leakage through the pipe threads. PS77 is formulated to give medium strength break torque, but lower prevail torque on assembled joints, thus enabling easier disassembly and servicing. Pipe joints made with PS77 should be fully torqued up within a maximum of 15 minutes from initial assembly. PS77 will give a rapid low pressure seal (after 20 mins).

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 Precautionary Information Refer to product label and material Safety Data Sheet for health and safety information before using the product.
