Description

M-CHEM 100 – Chemical Resistant Epoxy Coating

Is a Surface Tolerant, Chemical Resistant Epoxy Coating designed for the long-term protection of steel and concrete structures?

The coating when cured has excellent resistance to wide variety of commonly used chemicals.

M-CHEM 100 – Chemical Resistant Epoxy Coating can be applied to manually prepared steel and it tolerant to damp and condensation. The material can be used for applications operating at temperatures from ranging –20°C to 60°C.

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.

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 4 hours at 20°C, apply a topcoat at a minimum wet film thickness of 250 microns.
