Isocyanate component - polymeric diphenylmethane diisocyanate.
Scope of application
CAS-RBS SF-40 is used for the production of rigid polyurethane foam for seamless thermal insulation by spraying residential and industrial buildings, attics and other structures, thermal insulation of pipelines, industrial refrigerators and cold rooms.
Shelf life
The shelf life of component A is 12 months without opening the drums.
Rights
The data provided in this technical information is based on our current technical knowledge and experience and is believed to be accurate at the time of publication. Nothing in this publication should be construed as a warranty, either expressed or implied. Due to the abundance of factors that can influence the recycling and use of our materials, they do not excuse the recycler from its own testing and experimentation. In all circumstances, it is the user's responsibility to correctly determine the applicability of such information or of the product itself for a specific purpose of the user.
Preparatory measures before starting work
- Heat component A to +30 - 35 °C.
- Heat component B to +40 - 50 °C;
- Stir component A with a paddle mixer for 30 minutes at 500 - 1000 rpm;
- The isocyanate component (component B) does not require stirring if it has been stored at a temperature not lower than + 15 °C. If the isocyanate component was stored at temperatures below + 15 °C, then slowly heat it up to a temperature not higher than +50 °C.
Work surface requirements
- The surface must be dry, clean, dust-free, free from oils, crumbling and chipping areas.
- If the surface cannot be completely dedusted, then it is necessary to apply a primer.
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:
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:
- component A + 30 - + 35°C;
- component B + 40 - + 50 °C;
- hoses from + 30 - + 35 °C;
- pressure might be 60 - 120 bar
- air temperature in the working area and surface not less than +5 °C;
