SikaTop® Armatec®-110 EpoCem®
ANTI-CORROSION COATING AND BONDING AGENT
SikaTop® Armatec®-110 EpoCem® is a 3-component, water-based epoxy resin, anti-corrosion coating and bonding agent.
- Excellent adhesion to steel and concrete
- Acts as an effective barrier against penetration of water and chlorides
- Non-vapour barrier
- Contains corrosion inhibitors
- Provides an excellent bonding coat for subsequent applications of repair mortars
- Extended open time
- Not affected by moisture
- High mechanical strength.
- Premeasured, ready-to-use kits
- May be spray-applied
- Non-flammable
- Solvent-free
Usage
- As an anti-corrosion coating for reinforcing steel:
- For repairs to reinforced concrete where there is corrosion of the underlying reinforcement steel
- For preventive protection of reinforcement steel in thin reinforced concrete sections - As a bonding agent for use on concrete, mortar or steel:
- For repairs to concrete using SikaTop® Plus, Sika MonoTop® and SikaRepair® patching and repair mortars
- For bonding new concrete and mortar to old

Yield
Bonding agent: Minimum 8 kg or 4 L/6.6 m2 (17.6 lb or 1.05 US gal./72 ft2)
Anti-corrosion coating: 8 kg or 4 L/2.3 m2 (17.6 lb or 1.05 US gal./25 ft2)
MIXING
Shake components A and B vigorously before opening. Pour both liquids into a suitable mixing pail and mix for 30 seconds. Add component C slowly while continuing to stir the mixture. Mix mechanically for three (3) minutes, using a low-speed drill (300 - 450 rpm) and Jiffy mixer in order to entrain as little air as possible.
APPLICATION
Anti-corrosion coating: Apply coating approx. 0.5 - 1 mm (20 - 40 mil) thick on cleaned and de-rusted reinforcement steel using a stiff paint brush, roller or spray gun. Be sure to coat the underside of the totally exposed steel. Let dry for two (2) to three (3) hours [ambient temperature of +20 °C (68 °F)] before applying a second coat of similar thickness. Let dry for a similar period of time before applying patching mortar, or concrete, to the repair. In the course of application, some of the coating material will inevitably be deposited on the surrounding concrete, but this has no detrimental effect on the finished repair.
Bonding agent for repair mortar or concrete: Ensure that the prepared substrate is saturated surface dry (SSD), then apply a bonding coat no less than 0.5 mm (20 mil) thick, using a paint brush, roller or suitable spray gun. For best results, work the bonding slurry well into the substrate to ensure complete coverage of all surface irregularities. Freshly mixed patching mortar or concrete can be applied immediately on SikaTop® Armatec®-110 EpoCem® within the contact time: 8 hours at +30 °C (86 °F), 12 hours at +20 °C (68 °F), 16 hours at +10 °C (50 °F).
After this contact time, the adhesion characteristics will be reduced.
CLEAN UP
Use water to remove uncured material from tools and mixing equipment. Cured, product can only be removed mechanically.
