Armourguard ST
Surface tolerant epoxy-ceramic metal primer & coating with cutting edge polymer technology; perfect for water tanks, fish tanks and water treatment systems.
ARMOURGUARD ST is a recently developed two part epoxy-ceramic metal primer and coating that contains a functional liquid rubber that forms minute spherical droplets within the epoxy binder. After application the rubber reacts with the epoxy hardener rendering the coatin flexible and impact resistant. The rubber increases adhesion of the coating to the substrate, decreases permeability but surprisingly, does not decrease hardness or abrasion resistance.
ARMOURGUARD ST also contains a carefully selected package of corrosion inhibitors that inhibit the formation of rust beneath the coating.
ARMOURGUARD ST is a two part, low solvent epoxy-ceramic coating that contains 70% of solid ceramic micro-spheres and anti-corrosion additives that passivate the metal surface thus preventing corrosion.
ARMOURGUARD ST is virtually impervious to water, water vapour and oxygen. Its unique formulation eliminates the requirement for separate primers and undercoats because ARMOURGUARD ST’s superb barrier properties prevent oxygen and moisture reaching the substrate.

SUBSTRATE PREPARATION
Steel should preferably be shot or hydro-blasted and free from traces of soluble salts. It is especially important to remove all traces of salt from surfaces that have been immersed in sea water.
ARMOURGUARD ST can be applied to well prepared surfaces provided that they are free of loose or scaly rust, oil, grease or other contamination. ARMOURGUARD ST can be applied to damp (not wet) substrates when used with SYNAMIN 1055 hardener. Puddles and large drops of water should be mopped up or blown away with compressed air before application of the coating. ARMOURGUARD ST can also be applied to sound old epoxy coatings provided they are clean and have been abraded.
MIXING
Resin should be pre-mixed in the tin before the hardener is added, preferably with an electric mixer. After the hardener has been added to the tin mix for at least 2-3 minutes, pay particular attention to the sides and bottom corners of the tin to ensure that all materials are thoroughly incorporated. When mixed, the resin and hardener will start to react, generating heat. This will then accelerate the reaction. The greater the mass of epoxy, the more heat will be generated and the shorter the pot life. If you require a smaller quantity or are unable to use all of the material within its pot life, weigh out resin and hardener in the proportions specified on the label using digital kitchen scales.
APPLICATION
ARMOURGUARD ST can be applied with a brush, short pile roller or by high pressure airless or conventional spray equipment supplied with material from a pressure pot. For maximum protection three coats should be applied to a dry film thickness of 360 microns.
Advantages
- Excellent adhesion to metallic surfaces
- Excellent barrier properties prevent corrosion
- Tremendous abrasion resistance
- Surface tolerant & can be applied to damp substrates
