PROCESSING CASTING PROCESSING BY MACHINE<br />
• Heat both parts (isocyanate (1) and polyol) at 73° F/(23° C) in case of storage at lower temperature.<br />
• Weigh both 2 parts.<br />
• Mix for 1 minute minimum after degassing for 10 minutes under vacuum.<br />
• Cast under vacuum in silicone mold previously heated at 158° F/(70° C).<br />
• Demold after 45 minutes minimum at 158° F/70° C)<br />
(1) If <strong>PX</strong> <strong>527</strong> <strong>Part</strong> A Isocyanate is cloudy, please heat to 158°F/(70° C) until clear. Allow to cool to room<br />
temperature before proceeding.<br />
HANDLING PRECAUTIONS<br />
Normal health and safety precautions should be observed when handling these products :<br />
• Ensure good ventilation<br />
