MCU-Miozinc is a single component, moisture cure polyurea primer, combining zinc and micaceous iron oxide (MIO) into a proprietary blended moisture cure resin. This primer is designed to protect steel from corrosion in high humidity climates and is suitable for use in immersion, splash zones and areas with frequent condensation. The properties of the resin, high quality zinc and lamellar MIO provides both barrier and galvanic protection that prevents moisture and other corrosive agents from penetrating the coating and reacting with the steel substrate. MCU-Miozinc has superior abrasion & impact resistance and long term flexibility. 

MCU-Miozinc is also a suitable universal primer, excellent as a spot primer and for overcoating and overlapping with existing epoxy, polyurethane and alkyd coatings. MCU-Miozinc will not crack when applied at higher DFT’s, and it will not blister when applied to prepared steel with a low surface profile. 

  • Surface tolerant MIO/zinc filled universal primer. Outperforms inorganic zinc primers
  • High DFT tolerance – unlimited
  • Re-coatable by itself and compatible with most old coatings and metal alloys
  • Full or spot primer on hand and power tool cleaned, (wet/dry) abrasive blasted or UHP cleaned surfaces
  • Provides both barrier and galvanic protection
  • Overcoatable by itself
  • Does not require Sa 2.5 for maximum performance
  • Tolerates flash rusting
  • Superior abrasion/impact resistance and long term flexibility
  • Recommended for immersion, splash zones and atmospheric exposure
  • Will not blister when applied on surfaces with a low roughness profile
