Product introduction:

For AMMT-021 pipeline anti-corrosion material, A component is modified semi-prepolymer, B component consists of synthetic resin, amine chain extender, nano-filler and pigment, and it is sprayed into shape on the site. The technology unifies the new material, new equipment and new process together, breaking through the limitation that the polyurea/polyurethane material must be used with supporting primer in the past, and AMMT-021 can be directly sprayed on the steel surface.

Features:

· 100% solid content, 0 VOC and environment friendly.

· It has excellent physical performance and good adhesive force to the metal substrate

· It can cure fast, so the cycle of the coating can be reduced.

· Good resistance to water. oil, solvent, etc. after film formation

· Good weather resistance and non-efflorescent

Range of application:

AMMT-021 pipeline anti-corrosion material is mainly used for the anticorrosion of inside and outside walls of oil and gas pipelines, and it is suitable for oil pipelines, directly burried pipes, municipal sewage pipes and gas pipelines, etc.

Main performance indexes:

Color: Adjustable

Mass solid content: 100%

Mixing ratio: A: B=1: 1 (volume ratio)

Specific weight: About 1.0Kg/L

Construction description:

Construction condition: Temperature of painting substrate: 20℃- 45℃

The relative humidity is below 90%, the substrate surface temperature is over 3℃ higher than the dew point temperature and both the humidity and temperature shall be measured near the substrate.

Outdoor painting is not allowed in rainy, snowy, foggy or strongly windy days.

Construction method: Spray by special double-component equipment

The sparying pressure and nozzle dimension may be adjusted based on the specific requirements for sparying performance.

See the construction process for the detailed construction method.

Tool cleaning: DOP or special cleaning agent

Surface treatment: 

Direct coating: Treat to Sa2.5 level by sand blasting with the surface roughness of 55-70μm.

Primer coating: 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.

Compatibility:

Pre-process compatibility: Can be used directly; AMMT-016 special polyurea primer for concrete and AMMT-017 special polyurea primer for steel structure.

Packaging specifications:

A component: 200L/barrel

B component: 200L/barrel
