Poolkemie POLIMOLD TR 40

Poolkemie POLIMOLD TR 40 is a two component room temperature vulcanising poly-urethane rubber which cures with addition of the appropriate hardener. Once cured, this rubber becomes flexible and resistant, free from air bubbles and imperfections. It is suitable in the manufacture of molds for production of articles made of plaster and cement thanks to its accurate reproduction of fine details and due to its extremely low linear shrinkage.

Storage & Handling

Shelf Life

Both components (A and B) 8 months, stored in their original tightly closed containers, in a dry and fresh place at temperatures in the range from +5°C to +30°C. NOTE: The Component A contains isocyanic prepolymer which reacts with water and moisture. Therefore, once the container is opened, the material must be used within a few hours. In the case of partial utilization, fill the empty space with a coat of dried nitrogen. Mix carefully the Component B (polyol) before use.
