System Description
Two-component system for the production of rigid polyurethane foam by injection of the "RPC ZV-204" brand.
The polyol component (component A) of the RPC ZV-204(A) trademark contains polyesters, stabilizers, catalysts, flame retardants, and water.
Isocyanate component (component B) - polymeric diphenylmethane diisocyanate grades: Lupranat M 20 S, Millionate - MR 200, Wannate - PM 200, Desmodur VKS 20 F, Ongronat 2100, etc.
Scope of application
RPK ZV-204 is used for heat and sound insulation of inter-wall spaces.

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 or in the tank of the filling machine for 60 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;
Precautions and health effects
When processing, it is necessary to take into account safety measures according to TU.
