Polyol (component A) is a transparent liquid from yellow to brown colors.
Isocyanate component (component B) - polymer diphenylmethanediisocyanate brands: "Lupranat M 20 S", "Millionate-MR 200", "Wannate-PM 200", "Desmodur VKS 20 F", "Suprasec 5005", "Cosmonate M-200", "Ongronate 2100" - transparent non-delaminating brown liquid.
| Parameter | Value |
|---|---|
| Start time | 40-60 seconds |
| Rise time(time for gelatinization) | 140 -160 seconds |
| Apparent density during the free foaming | 80-100 kg/m3 |
| Density (in the core) | 285 kg/m3 Not less than 270 kg/m3 |
| Durability on compression at 10% deformation in the radial direction | 1.35 MPa, but not less than 1.2 MPa |
| Water absorption in fully submerged state | 0.35%, not more than 0.5% |
| Thermal conductivity coefficient at an average temperature of 50°C | 0.033 W / m°C, but not more than 0.035 W / m°C |
To ensure the reactivity and viscosity of the components, before processing bring the temperature of the component A to (+20) °C- (+25) °C, component B (+20) °C- (+25)°C. Mix the polyol component (component A) with a paddle for 10-15 minutes or roll the barrels in a horizontal position for 20-30 minutes. The isocyanate component (component B) does not require any stirring if it was stored at a temperature not lower than +15°C. If the isocyanate component was stored at a temperature below +15°C, then slowly heat it to a temperature not higher than +25°C. Roll the barrel in a horizontal position to a homogeneous (homogeneous) state.
Flammable liquid. Contains flammable compounds, keep away from sources of fire, sparks, do not smoke near by the liquid. It can cause an irritation, if contacts the skin; and it can cause irreversible consequences in case of a contact with eyes. Can contaminate objects in the environment.
When working with the system, use an insulating gas mask, a BKF or B gas mask, safety glasses with side pads, impermeable synthetic rubber gloves, clothing and shoes. The space where the work is carried out must be equipped with exhaust ventilation, workplaces – local suction and fire extinguishing means.
Store in a ventilated area/ warehouse at a temperature from (-60)°C to (+30)°C, away from any heating devices, fire sources and oxidizers.
