Features and Benefits
• Medium strength formulation for good retention between close-fitting cylindrical parts
• Prevents loosening and leakage between bonded parts
• Available in a range of sizes to suit individual requirements

Typical Applications
• Ideal for parts that need subsequent dismantling, i.e. retention of bearings on shafts and in housings
