Recommendations for processing:
The key conditions for the qualitative filling of a form with polyurethane foam are: compliance with the accuracy of dosage and temperature conditions of the PU-system components' processing regime; sufficient mass of the poured PU-system portion; proper preparation and required temperature of the mold working surface.
POLYSYSTEM 600(130) PU-system is processed by filling open or closed metal molds of various sizes and configurations by means of high- or low-pressure machines, or manually. Before the actual filling, the molds are cleaned and lubricated with anti-adhesive lubricant (based on waxes, oils, silicones, etc.), which ensures easy and quick removal of finished products.
Optimal temperature of the mold working surface is (35 - 55) °C.
Before processing, the components are thermostated up to (18 - 22) °C.
The product curing time is 10 - 20 minutes (depending on its size and configuration).
Once the curing time is over, the product is removed from the mold and kept for 24 hours in a room with a temperature not lower than 18 °C - to ensure the final curing of polyurethane foam. Technical documentation for the equipment and the process of obtaining finished products are the guidelines for the PU-system processing.

Handling and storage
POLYSYSTEM 600(130) Component A warranty period of storage is 6 months - when stored in a dry place in a hermetically sealed manufacturer's container at a temperature of (10 – 25) °C.
Component B warranty period and storage conditions - in accordance with the technical data provided by the manufacturer. The POLYSYSTEM 600(130) PU-system technical requirements and Component B safety passport are the guidelines for the transportation, storage, handling and safety of these materials. These documents are updated periodically. Ask manufacturers and/or suppliers for updated versions of relevant documents before using the PU-system. When working with the above-mentioned materials, it is necessary to pay attention to personnel health, to compliance with safety and health regulations, as well as to environment safety.
