The primary functions of anaerobic resins are:  \nEach one of these functions is based upon control of five major variables: strength, viscosity, adhesion, flexibility and temperature resistance. These five parameters give anaerobics users considerable latitude in adjusting properties for optimum performance in specific application areas.  \nAnother variable that should be considered is the substrate in which the adhesive will be applied. For certain substrates or other special requirements, the use of primer is recommended.  \nWHY USE A PRIMER?  \n1. Primers activate inactive surfaces which are not required with primerless products.  \n2. Primers speed cure times for faster return to servic","cbCaikTxf40dG6GG","https://ap.wps.com/l/cbCaikTxf40dG6GG","pdf",556303,"English","# INTRODUCTION\n## Introduction to Anaerobic Adhesives and Sealants\n## Why Use a Primer?\n# THREADLOCKING\n## Thru Holes (Bolts and Nuts)\n## Blind Holes (Cap Screws, etc.)\n## Blind Holes (Studs, etc.)\n# THREAD REPAIR\n## Stripped Thread Repair\n# THREAD SEALING\n## Standard Fittings – Pipes, Hydraulic or Air\n## Pipe Unions\n## Compression Fittings\n## Flared/Swaged Fittings\n## Hose Ends – Air & Hydraulic\n# POROSITY SEALING\n## Existing Weld Porosities and Castings\n## Sealing New Welds – Preventive Maintenance\n# FORM-IN-PLACE GASKETING\n## Sealing Cast Rigid Flanges\n## Gasketing Quick Selector\n# GASKET DRESSING\n## Sealed Flanges\n# FORM-IN-PLACE SILICONES\n## Stamped or Sheet Metal Flanges\n# STRENGTHEN KEYED ASSEMBLIES\n## Standard Duty\n## Heavy Duty\n## Repairing Badly Wallowed Keyway\n# SHAFT MOUNTED ASSEMBLIES\n## Repairing Badly Worn Shaft\n## Slip Fit – Light/Heavy Duty\n## Press Fit\n## Shrink Fit\n# HOUSED COMPONENTS\n## Slip Fit\n## Repairing Badly Worn Housing\n## Component Centering\n## Sealing/Retaining – Metallic Seal Retaining Compound Quick Selector\n# DISASSEMBLY\n## Threadlocking, Thread Sealing & Retaining Gasketing\n# SHAFT REPAIR\n## General Information\n# BONDING\n## Introduction to Bonding Adhesives\n## Bonding Assembly\n## Surface Preparation\n## Adhesive Quick Selector\n## O-Ring Making\n## Bonding Metal Label\n## Filling Cracks\n## Structural Bonding\n# RUSTPROOFING\n## LOCTITE® Extend® Rust Treatment\n# CLEANING\n## General Purpose Parts Cleaning\n# TROUBLESHOOTING\n## Checklist\n# ORDERING\n## Product Listing/Order Information","[{\"question\":\"What is the purpose of anaerobic adhesives and sealants in this guide?\",\"answer\":\"They convert from liquid to a tough structural solid in the absence of air and the presence of metal, providing core functions that support reliable maintenance and overhaul needs.\"},{\"question\":\"When should a primer be used?\",\"answer\":\"Primer use is recommended for certain substrates or special requirements.
