Description

M-PRIME 200 - Aluminium Based Metal Primer

Is an Aluminium based Metal Primer with an extremely high solids content. And when applied as a two-coat system provides corrosion resistance more than 10,000 hours when tested to ASTM B117.

M-PRIME 200 – Aluminium Metal Primer is Surface Tolerant and can be applied to surfaces where standard preparation techniques such as grit-blasting is not possible. In these circumstances’ hydro-blasting or mechanical hand tools will be acceptable. 

The product is designed to provide long-term corrosion protection for steel structures and can applied by brush, roller, or standard airless spray. The product is typically used, as a base coating in conjunction with a wide range of epoxy, polyurethane coatings, and UV stable topcoats.

M-PRIME 200 – is highly resistant to marine and industrial environments, effluents, salt water, oils, and a wide range of industrial chemicals.

Typical Uses

  • Corrosion Resistance Coating for Storage tanks
  • Protects Structural Steel
  • Primer for Pipelines
  • Corrosion Barrier for Marine Structures
  • Surface Tolerant Primer for Industrial Equipment

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.
  1. All surfaces must be hydro-blasted using clean water at 12,000 psi (850bar) to NACE 5 (SSPC SP13 WJ3-WJ1).
  • 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.
  • 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 primer as soon possible after mixing.

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

Brush or 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 sufficiently apply a basecoat to all surfaces at 150 microns wet film thickness.
  • Under normal circumstance 1 coat should be acceptable if the primer is used in conjunction with Epoxy or Polyurethane intermediate and topcoats.
  • If a second coat is required allow the basecoat to cure for approximately 6 hours at 20°C.
  • Apply a second coat to all surfaces at 150 microns wet film thickness.
