Preparatory measures before starting work

Work surface requirements

Processing conditions

When spraying polyurethane foam, it is necessary to control the thickness of the layers. In one pass, apply a layer of no more than 25 mm so that the gases that are released during the foaming process have time to escape, the cells are uniform without breaks and voids. The polymerization process is accompanied by a release of temperature. If layers over 25 mm are applied, interlayer overheating is possible, which will lead to the formation of voids.
If the surface temperature for spraying is below + 15 °C, then it is necessary to apply a polyurethane foam primer layer no more than 2 mm thick, wait until the primer layer becomes elastic, then apply the main layers.
Recommended temperature and pressure:

1. component A + 30 - + 35°C;
2. component B + 40 - + 50 °C;
3. hoses from + 30 - + 35 °C;
4. pressure might be 60 - 120 bar
5. air temperature in the working area and surface not less than +5 °C;
