Epo-chem™ RS 500P

Jump To:

Two pack solvent-free, wet and rust tolerant epoxy primer.

Epo-chem RS 500P is a solvent-free, wet & rust tolerant primer or primer-finish epoxy system. The use of special sacrificial fillers enables the system to be applied to surface standards as low as WJ-4, St 2. The system’s long-term performance is based on completely sealing (porous-free film) and arresting the rust totally.

It is typically applied as a 1-coat system which can be over coated by itself or with the topcoat Epo-chem™ RA 500M.

Acts as an excellent multi-purpose tank lining system when topcoated with RA 500M for the following tank applications:

Sea Water Ballast (Lloyd's Register & ABS Approved) Crude Oil (ABS Certified)
Potable Water (NSF & FDA Certified) Refined Oil (Diesel/Petrol)
Grey/Black Water Cargo (Food Contact Approval)
Sewage Mud/Brine


Applying RS 500P  on a sweating and wet substrate

Primary Features:

  • Solvent-free (odourless), wet & rust tolerant primer or primer-finish epoxy system
  • Tested and Certified by NSF for fresh drinking water applications. Epo-chem™ RA 500 or RA 500M is used as the topcoat
  • Flexibility on the surface preparation standards or method, i.e. the most convenient method depending on availability or cost, e.g. grit blast, wet blast, HP water jetting (500-800 bars), UHP or mechanical (St 2 - St 3)
  • Can be applied directly on top of shop primers
  • Apply in any environmental condition, no humidity restrictions - can be applied on sweating and soaking wet substrates
  • Extensively used for internal tank linings, ballast tanks or confined spaces
  • No overcoating limitations
  • No requirements for dehumidification, ventilation or heating (substantial cost savings)
  • Reduced H&S and Fire Precaution
  • Long-term corrosion protection (new MIO-Zinc technology)
  • Excellent adhesion to rusty or poorly prepared and wet surfaces (>1200psi)
  • One coat (without the topcoat) protects the substrate in excess of 10 years (independent test certificates available)
  • Zero VOC, no fire hazard or odour
  • Can be applied as a single high-build coat (up to 250 microns per coat)
  • Can be utilised for outside contracts in inclement weather condition reducing downtime
  • Very good workability and easy to apply by brush, roller or spray
  • Ideal as a repair system on existing coatings as it is compatible with almost all protective coatings, including coal-tar epoxies
  • Sufficient UV resistance and colour stability; can be overcoated with coloured topcoats
