Description

3M™ Scotch-Weld™ Pipe Sealant Anaerobic Adhesives are one-component

anaerobic sealants that cure and seal hydraulic and pneumatic pipes and fittings to

withstand high temperatures and pressures

Specific

Features



3M™ Scotch-Weld™ Pipe Sealant Anaerobic Adhesives HP42 is formulated to lock and

seal fine to medium pipe threads, particularly for hydraulic and pneumatic pipe systems, up to

15mm pipe diameter. HP42 prevents vibration loosening and leakage through the pipe

threads. It is formulated to give medium strength break and prevail torque on assembled

joints, thus enabling easier disassembly and servicing. Pipe joints made with HP42

should be fully torqued up within maximum of 10 minutes from initial assembly. HP42 will

give rapid low pressure seal (after 20 minutes)



3M™ Scotch-Weld™ Hydraulic Pneumatic Sealant HP45 is a low breakaway

torque strength, medium viscosity liquid sealant for most high pressure hydraulic and

pneumatic fittings. It has excellent solvent resistance.



3M™ Scotch-Weld™ General Purpose Pipe Sealant PS65 is a general purpose, low

to medium breakaway torque strength paste pipe sealant. It is formulated to lock and

seal medium to coarse straight and tapered pipe threads on pipes of diameter from

approximately 5/8" to 3". It is used for applications that require easy disassembly.



3M™ Scotch-Weld™ Stainless Steel High Temperature Pipe Sealant PS67 is a fast

cure, low breakaway torque strength, high temperature paste pipe sealant for metal

connections in applications such as pressure vessels, air compressors, hydraulic, and

pneumatic systems. It works on inactive surfaces (such as stainless steel) and provides

an almost instant low pressure seal. A high pressure seal results when the bond is fully

cured.

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 minutes)
