Technical specifications
The main material
Substrate processing
Clean the surface of steel components foreign body and rust, metal surface treatment of oil, to rust Standard ST2
Bottom
The thickness of the main ingredients of the binder and water in accordance with a certain proportion of mixing evenly, brushing or spraying the surface of the substrate 1-2 times, the table can be dry for the next construction
NH-1180 thick fire retardant coating
Fire paint construction
The use of spraying equipment construction, each spraying thickness of 5-10mm, separated by 12-24 hours spray again, until the required thickness so far, Bureau of repair can be hand-painted.
NH-1180 thick fire retardant coating
Putty construction
Wipe the putty on the thick coating surface, dry and polish smoothly
Other brands of putty
Topcoat construction
In a smooth putty layer, spray 1-2 times strong weathering oily topcoat for protection or decoration thick paint
Lanling / Rolls polyurethane finish
note:
Construction Conditions:
1, the temperature is below 5 ℃, relative humidity greater than 90%, the wind speed is greater than 5m / s or rainy days and steel structure surface dew condensation should not be construction;
2, paint the construction interval should be controlled at 12 ~ 24h (temperature at 20 ℃), not too long or too short, the general winter may be appropriate to extend the summer is appropriate to shorten. When the weather is hot or extremely dry, it is necessary to create the necessary curing conditions (plastic film cover, surface brushing water, etc.), otherwise it will affect the binding force of paint layer and easily cause hollowing, falling off and powdering;
