Product details

Product introduction:

AMMT-016 Polyurea special primer is one thin coating primer composed of isocyanate prepolymer, curing agent, environment friendly solvent. Fast drying speed, Can effectively seal the concrete substrate. It can close the moisture and air holes of the concrete base and correct the small defects on the surface of the base, improve the adhesion between the polyurea coating and the concrete substrate, and increase the bonding strength between the concrete base and the polyurea coating.


Features:

●Excellent adhesion

●Good matching

●Low dosage


Application:

Primarily used as a primer for polyurea materials, to achieve a good adhesion of polyurea material. At the same time can be used for special primer to polyurea material steel substrate.

Construction condition:

Coating substrate temperature: Minimum 5℃maximum of 45℃

Relative humidity below 90%, the substrate surface temperature above the dew point temperature above 3 degrees, temperature and humidity should be measured near the substrate.

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

Construction method: Using single spraying equipment or brush coating


Non gas spraying

brush coating

Spray pressure

8~12MPa


Nozzle diameter

525



Spraying pressure and nozzle size may be adjusted according to appropriate requirements of painting performance.

The primer can be sprayed or brushed by hand. When applying, apply force repeatedly to the surface to be painted, or apply it in a circle, which will help the paint to fully wet the surface and enhance the adhesion of the paint film. At the same time, check carefully to ensure that there are no missing areas.

Tool cleaning: Methyl ethyl ketone


Surface treatment:

After the concrete be completely dryd (newly prepared concrete should be cured for 28 days), the surface should be sanding or shot blasted to remove loose impurities on the surface. Old concrete is used to repair the holes and cracks with putty.

When coating on the surface of concrete, the thickness of the coating film can be 30 ~ 50μm, without being too thick. If the concrete strength is poor, the thickness of the coating film or the number of construction channels can be increased appropriately. The penetration of primer can greatly improve the tensile strength of concrete.
