Product Description

RXSILICONE RX-1120

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.
Applications:
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?
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).
