Descripation:
RTV-2 life casting silicone rubber is two-component addition cure heating or room temperature vulcanizing silicone rubber ,the product, which is colorless or skin-colored oily liquid and becomes soft elastic material after vulcanization, can be used for making soft silicone rubber.
Characteristical:
• Easy to use
• Use platinum catalyst
• High degree of precision in reproduction
• High transparency,almost non shrinkage
• Good heat stability and weatherability(resist -60 to 250°C)
• Low compression set,grat stability and ability to resist extreme temperatures of heat and cold.
Application:
• Paster
• Traction
• Sex toys
• Body organs
• Shoulder pads
• Body breast enhancers
• Other soft silicone products

How to make mold?
1.Mixing
Please weight 1 Part A base and 1 parts 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 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 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.
