Processing Conditions<br />
• Vacuum casting into silicone molds.<br />
• Heat both parts to 64°F (18°C) when stored at lower temperature.<br />
• Important: vigorously shake Part B Polyol before each and every weighing.<br />
• Degas each part before use.<br />
• Mix for a minimum of 30 seconds.<br />
• Pour into mold preheated to 149 – 158°F (65 – 70°F).<br />
• Cure for 60 – 75 minutes at 158°F (70°C) before demolding<br />

Storage Conditions<br />
Product shelf life is 6 months when stored in original unopened containers between 59 – 77°F (15 – 25°C). Any<br />
opened can must be tightly closed under protective gas blanket, such as Bloxygen (available from Axson).<br />
Part A (Isocyanate) may crystallize at temperatures below 59°F (15°C) as indicated by a non-homgeneous<br />
appearance, heat product to 158°F (70°C) until uniform.<br />
Part B (Polyol) separates rapidly in storage. Please shake vigorously before each use to ensure best results.<br />
Handling Precautions<br />
Normal health and safety precautions should be observed when handling these products:<br />
• Ensure good ventilation<br />
• Wear gloves and safety glasses<br />
For further information, please consult the material safety data sheet.<br />
