Epo-chem™ RS 500P and Epo-chem™ RA 500M

Ballast tanks and double bottoms are areas of complex steel structure with poor access and permanent condensation. Chemco’s solvent-free, wet & rust tolerant primer Epo-chem™ RS 500P and solvent-free, wet tolerant, glassflake epoxy topcoat Epo-chem™ RA 500M are perfectly suited for small patch repairs or complete refurbishment.

This solvent-free, wet & rust tolerant system has passed independent tests for IMO Resolution MSC.215(82) for application in sea water ballast tanks on bare steel, shop primed steel and uniquely on wet & rust steel.

Millions of square metres of this revolutionary coating system have now been applied in sea water ballast tanks by almost all major shipping companies throughout the world.
