• Moderate thermal conductivity
• Room temperature or heat accelerated cure
Benefits:
• Rapid, versatile cure processing controlled by temperature
• Can be considered for uses requiring added flame resistance
Composition:
• 1 to 1 Mix Ratio
• Polydimethylsiloxane
• platinum curing agent
Applications:
Suitable for general potting material for power supplies, connectors, sensors, industrial controls and transformers.

How to make mold?
1.Mixing
Please weight 1 Part A base and 1 parts of platinum Catalyst in a clean container.Thoroughly stir Part A base silicone before use, as filler separation may occur upon prolonged storage. Mixing Part A and Part B evenly until part B completely dispersed in the base. Hand or mechanical mixing can be used,but do not for an extended period of time or allow the temperature to exceed 35°C. Mix suitably small quantities to ensure thorough mixing of base and catalyst.
It is strongly recommended that entrapped air be removed in a vacuum chamber,allowing the mix to completely expand and then collapse. After a further 1-2 mins under vacuum,the mix should be inspected and can be used if free of air bubbles. A volume increase of 3-5 times will occur on vacuum de-airing the mixture. So a suitably large container should be chosen.
2.Pouring the mixture and curing
Pour the mixed Part A base silicone and part B platinum catalyst as soon as possible onto the original,avoiding air entrapment.The catalyzed material will cure to a flexible rubber within 24 hours(or faster by different mixing ratio or room temperature).
Storage:
When stored at or below 30°C in the original unopened containers,SILASTIC Base and platinum Catalyst have a usable life of 12 months.from the date of production.After 12 months stock,pls use the Stir to mixing the Part A silicone for some mins, then the silicone can be use again,no influence for other performance.
