Preparation and processing
- 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 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.
- Set the temperature on the mold to 20-30°C
- The ambient temperature should be at least 20°C.
Processing requirement
Processing is performed on high-and low-pressure filling machines in accordance with Himtrust Technical Conditions Manual.
- Ratio of the components A to B by weight should be: 100: 140.
- The temperature of the components A and B should be (+23) – (+25) °C.
- The density in the finished product is not less than 60 kg / m3.
- Exposure of the finished product should last 48 hours at a temperature of (+ 20) -(+30) °C.
Health effects and precautions
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.
Storage recommendations
The warranty period is 12 months at a temperature of 20°C without opening the barrels.
