Product introduction:

Component A of AMMT-031 protective material dedicated for sewage treatment pool is the modified isocyanate quasi-prepolymer, and component B is composed of amine-terminated polyether, modified delayed amine chain extender, and anti-aging additives. The material is formed by site spraying. The technology combines the new material, new equipment and new process, which is applicable to the protection of concrete corrosion in seawater splash zone, and also to the protection of steel structure in the sea.

Features:

●No VOC, environmentally friendly

●Used in combination with the matching primer, it shows excellent adhesive force against concrete/steel substrate.

●Good resistance to water. oil, solvent, etc.

●The coating is seamless with excellent water-proof and anti-corrosion performance; 

●High elongation, resistant to cold and heat alternation without cracking.

●Good weather resistance without chalking and blanking.

Application:

AMMT-031 protective material dedicated for sewage treatment pool is applicable to such fields as the protection of the concrete/steel structure in seawater splash zone, the waterproof of the roof of advanced buildings, industrial factory building, vapor barrier for cold storage, reservoir, bridge, tunnel, underground construction and the cooling tower of power plant, waste/activated sludge tank and aquarium.

Construction description:

Construction condition: Temperature of coating substrate: minimum: 5℃; maximum: 45℃

relative humidity: less than 90%; surface temperature of substrate: at least 3℃ higher than dew point temperature. Both the humidity and temperature shall be measured near the substrate. Outdoor painting is not allowed in rainy, snowy, foggy or strongly windy condition.

Construction method: Spraying with special two-component equipment

The spraying pressure and nozzle dimension may need adjustment based on the specific requirements for spraying performance.

Tool cleaning: Methyl ethyl ketone

Surface treatment: Paint the polyurea material within the effective coating interval of special primer for polyurea and paint the special primer again if exceeding the effective coating interval time.

Compatibility:

Pre-process compatibility: AMMT-016 special polyurea primer for concrete; AMMT-017 special polyurea primer for steel structure.  

Packaging specifications:

Component A: 200L/barrel

Component B: 200L/barrel

Storage:

The product shall be stored in cool, dry and ventilated warehouse and away from heat or fire source. The packaging container shall be kept sealed for a storage period of one year.

Safety:

No fire source is allowed on the coating material mixing and construction sites, where the ventilation shall be satisfactory. Coating material construction personnel must wear protective devices to avoid skin exposure. When the coating material is splashed on skin, it's necessary to wash with proper cleaning agent or soapy water immediately and seek medical advice.
