Description

M-RUBBER 100 – Elastomer Repair Putty

M-RUBBER 100 is a two component fast curing solvent free urethane elastomer. The product has been designed to repair a wide range of rubber surfaces such as Nitrile, Neoprene & Natural rubber.

The material is easy to use, is solvent free and has flexible and rapid curing properties.

 

Typical Uses

  • Damaged conveyor belts
  • Sealing gaskets
  • Lining of process equipment

Please contact us to discuss your project before purchasing this material to confirm suitability.

Application Guide

  • All oil and grease must be removed from the surface using an appropriate cleaner such as 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.
  • Once surfaces have been prepared, apply a multi surface primer using a brush.
  • 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.
  • Once surfaces have been prepared, apply a multi surface primer using a brush.
  • All surfaces must be repaired before gingering or oxidation occurs.

 

PLEASE NOTE: Soluble salt contaminated surfaces the substrate must be pressure washed with clean water and checked for salt contamination this process may need to be repeated several times.

Concrete

  • If the concrete surface is contaminated, pressure wash using clean water.
  • Once the concrete is dry lightly abrasive blast or scarify taking care not to expose the aggregate. 
  • Once surfaces have been prepared, apply a multi surface primer using a brush.

 

Prior to mixing please ensure the following:

  • The base component is at a temperature between 15-25°C.
  • Do not apply the material when the ambient or substrate temperature is below 5°C.
  • M-RUBBER 100 is supplied in a 420gm cartridge with the base and activator components pre-measured.
  • Heat the cartridge to 20-25˚C before use.
  • Cut off the end of the mixing nozzle to ensure you have the largest dispensing capacity.
  • Unscrew the cap on the end of the 420gm cartridge and place in the cartridge gun and then attach the mixing nozzle.
  • Dispense the mixed product onto the repair surface and smooth out using the applicator tool provided.
  • If it is not practicable to heat the cartridge to 20-25˚C, do not use the mixing nozzle. Unscrew the cap on the  end of the 420gm cartridge and place in the cartridge gun.
  • Dispense the base and activator components onto a clean mixing surface.
  • Use the spatula provided to mix the base and activator components until you have a uniform mixture then apply the material to the repair surface
