Product Description


Pourable ,Condensation Cure Mold Making RTV2 Silicone Rubber
Condensation tin cure molding silicone rubber, Tin-based silicone, also called condensation-cure
silicone, are two-component materials which cure at room temperature (RTV) to flexible, high
tear-strength rubbers. Tin cured silicone can be poured onto models or they can be made
brush-able by adding a Thixotropic additive. They are ideal for molds where easy release or high
temperature resistance is required.
Condensation Cure Mold Making RTV2 Silicone Rubbers can be poured or brush onto products
for casting polyurethane,epoxy, polyester resin, gypsum/plaster, cement, waxes, low melt
alloys/metals, etc.

How to make mold?
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).
