Typical Uses

  • Machinery Shimming and Choking
  • Large Shaft Repairs
  • Pump Casing Defects
  • Repair Worn Bearing Housings
  • Leaking Flange Repairs
  • Leaking Tank Seams
  • As a Structural Adhesive

Application Guide

  • All oil and grease must be removed from the surface using an appropriate cleaner such MEK or similar type solvent.
  • All surfaces must be abrasive blasted to ISO 8501/4 Standard SA2.5 (SSPC SP10/ NACE 2) minimum blast profile of 75 microns using an angular.
  • Once blast cleaned, the surface must be degreased and cleaned using MEK or similar type solvent.
  • All surfaces must be coated before gingering or oxidation.
  • All oil and grease must be removed from the surface using an appropriate cleaner such as MEK.
  • All surfaces must be mechanically abraded using handheld grinders to ISO 8501/4 ST3 (SSPC SP3 ST3).
  • Once abraded, the surface must be degreased and cleaned using MEK or similar type material.
  • All surfaces must be repaired before gingering or oxidation occurs.

Prior to mixing please ensure the following:

  • The base component is at a temperature between 15-25°C.
  • The ambient & surface temperature is above 5°C or less than 3°C  above dew point.
  • Mix PART B with PART A in full units as supplied.
  • For small quantities us a mixing ratio of: 3:2 BY VOLUME OR 1.7:1 BY WEIGHT   
  • When mixing both materials, it is very important to have a uniform streak free fluid.

Use all mixed material within 60 minutes at 20°C.

  • Using a short-bristled brush, spatula or applicator tool, apply the material to the prepared repair area.
  • Ensure the product is pressed into any holes, scars or cracks before building up to the the quired thickness.
  • Minimum – the applied material can be over-coated as soon as it is touch dry.
  • Maximum – the over-coating time should not exceed 6 hours.

Where the maximum over-coating time is exceeded, the material should be allowed to harden before being abraded or flash blasted to remove surface contamination.
