EPOXY-CERAMIC BALLAST TANK COATING

ARMOURGUARD BT has been developed for coating ballast tanks where long term flexibility is required to cope with movement, expansion and contraction caused by extremes of temperature. Its unique formulation eliminates the requirement for separate primers and undercoats because ARMOURGUARD BT’s superb barrier properties prevent oxygen and moisture reaching the surface of the substrate.

• Excellent adhesion to the substrate
• Virtually impervious to moisture vapour
• Surface tolerant & can be applied to damp substrates
• Totally solvent free

ARMOURGUARD BT is a  two-part, solvent free epoxy co-polymer coating  containing 70% of solid ceramic micro-spheres. The cured coating contains the maximum possible amount of ceramic, which forms a flexible composite coating with far superior adhesion, abrasion and corrosion resistance than normal epoxy coatings.

ARMOURGUARD BT is virtually impervious to water, water vapour and oxygen. ARMOURGUARD BT also contains a carefully selected blend of additives to enhance adhesion to steel and existing coatings.

ARMOURGUARD BT should preferably be applied to shot or hydro-blasted steel that is free from traces of soluble salts. ARMOURGUARD BT can be applied to damp substrates without  detriment to the durability of the coating. Puddles and large drops of water should be mopped up or blown away with compressed air before application of the coating. ARMOURGUARD BT can also be applied to most sound old epoxy coatings provided they are clean and free from contamination.

ARMOURGUARD BT can be applied in temperatures between 12ºC and 40ºC. It is cured with SYNAMIN 1040 series hardeners which are available in three reactivities to suit the ambient temperature. The most suitable hardener for the application conditions will be supplied to give a pot life of 1½ to 2½ hours.  ARMOURGUARD BT can be over-coated as soon as it has cured sufficiently to accept the next coat but must be over-coated within the time shown on the table below.

ARMOURGUARD BT can be applied with high pressure airless spray equipment, by roller or by brush. For maximum protection three coats should be applied to a dry film thickness of 300 microns. A dry film thickness of 100 micron will allow a coverage of approximately 8m² per litre.

ARMOURGUARD BT is available in light and mid grey, and off white. Other colours are available to order
