Description

M-CHEM 101 – Chemical Resistant Epoxy Coating - Extended Cure

Is a Surface Tolerant, Chemical Resistant Epoxy Coating with a Extended Pot Life. 

The coating when cured has excellent resistance to wide range of commonly used chemicals and is typically used to protect concrete or steel stuctures.

M-CHEM 101 – Chemical Resistant Epoxy Coating – Extended Cure  can be applied to manually prepared steel and it tolerant to damp and evironment subject to condensation. 

This two-component product is highly resistant to marine and industrial environments, buried conditions, ground water, effluents, salt water and a wide range of oils and chemicals

Typical Uses

  • As an Internal Pipe Lining
  • lining for Fuel Storage Tanks
  • Chemical Resistant Lining for Storage Tanks
  • As a Chemical Resistant Floor Coating
  • To Protect Bunds & Containment Area’s from Chemical Attack

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.

Existing 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.
  • Clean all dust and debris from the surface and take several moisture readings and prime with M-PRIME 100 – Low Viscosity Epoxy Concrete Primer or M-PRIME 104 – Damp Tolerant Concrete Primer dependant on the moisture readings obtained.
  • Apply M-PRIME 100 or M-PRIME 104 at a target wet film of 150 microns, allow to cure before overcoating.
  • For very porous surfaces a second coat of primer may be required.

New Concrete

  • Allow new concrete to cure for a minimum of 21 days lightly abrasive blast or scarify to remove any surface laitance.
  • Clean all dust and debris from the surface and take several moisture readings and prime with M-PRIME 100 – Low Viscosity Epoxy Concrete Primer or M-PRIME 104 – Damp Tolerant Concrete Primer dependant on the moisture readings obtained.
  • Apply M-PRIME 100 or M-PRIME 104 at a target wet film of 150 microns, allow to cure before overcoating.
  • For very porous surfaces a second coat of primer may be required.

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.
  • Transfer the contents of the Activator unit into the Base container.
  • Using a low speed electric paddle mixer, mix the 2 components until a uniform material free of any streaks is achieved.
  • Once mixing is complete, use the mixed paste as soon possible after mixing.

Use all mixed material within 20-25 minutes at 20°C.

Application – Brush & Roller

  • Pour the mixed material into a paint kettle or paint tray (this will maximise the usable life)
  • Stripe coat all edges, joints & corners.
  • Once the stripe coat has cured and is capable of being overcoated, apply a basecoat at a minimum wet film thickness 250 microns.
  • Once the basecoat has cured sufficiently, approximately 10 hours at 20°C, apply a topcoat at a minimum wet film thickness of 250 microns.

Application – Spray

  • Spray application should be carried out by airless spray using a 60:1 ratio pump with an attached hot water pump to heat the spray lines.
  • The temperature of the spray lines should be kept around 25-35°C.
  • Spray pressure of 3600psi and a tip size of 19-23 thou should be used.
  • Use as short a line as possible to maintain product temperature (maximum 8meters).
  • Circulate the product for a short time to achieve a consistent temperature.
  • Apply a basecoat to all surfaces at aminimum 250 microns wet film thickness.
  • Once the basecoat has cured sufficiently, approximately 10 hours at 20°C. apply a topcoat to all surfaces at a minimum 250 microns wet film thickness.
