Castfil PTEF Putty Brushable

Introduction

Castfil PTFE putty / Brushable is a two part epoxy based cold weld metal repair system suitable for temperatures up to 120°c. Castfil is a self-lubricating compound possessing high mechanical strength. It bonds to most metals / plastics and offers long life protection against wear, abrasion & corrosion.

Applications

  • Repair of scored guideways
  • Filling of bolt holes in machine tool guideways
  • Repair of blowholes, porosities, discontinuities, etc in castings
  • Repair of damages caused by abrasion or corrosion
  • Rebuilding of critical machined parts
  • Repair of oversized bearing housing, worn out shafts, etc
  • Prevention of leakage in gas or liquid pipelines or valves
