BlueStar 585 Tin Cure Liquid Silicone Mould Rubber Condensation Silicone
Product Description
Condensation cure, tin cure liquid silicone, RTV 2 mold making silicones are generally named as two-part silicone rubbers which vulcanise, or cure, at room temperature. Part A is a dynamic liquid silicone/Part B is the curing agent (tin catalyst).

Various Applications of silicone liquid rubber
Construction of moulds for gypsum, soap, candles, concrete, resin products, artificial (very lightweight) stone, wax or custom moulds;
Decorative building moulds (cornice, column, balustrade, ceilling roses, pedestals, fountains, mantels, wall ornament, planter etc;
Resin crafts, epoxy resin crafts, poly resin crafts, polyester resin
Advantages of our rtv liquid moulding silicone :
exceptional fluidity and good operability, easy to demold.
Cures at room temperature within 3-4 hours (assuming constant temp of 25 degrees C).
Good tensile and tear strength, low shrinkage (<0.3%)
High duplication levels or longevity
Good resistance to weather, temperature, aging, acid.
Long shelf life (12 months at least) if kept at constant temperatures.
Operation Instructions of Silicone Liquid Rubber
How to make the silicone mold?
The surface of the original should be clean and free of loose material. If your products with thin flower patterns, and especially with porous substrates, please use a suitable mold release agent such as soap water, detergent, Vaseline or petroleum jelly.
Mixing
Please weight 100 Part A base and 2 parts of Curing Agent 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 the CA30 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 35C (95F). Mix suitably small quantities to ensure thorough mixing of base and curing agent.
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.
Pouring the mixture and curing
Pour the mixed Part A base silicone and part B the curing agent as soon as possible onto the original, avoiding air entrapment. The catalyzed material will cure to a flexible rubber within 6 hours (or faster by different mixing ratio or room temperature), we advice you de-mold after 24 hours, it is will improve the replicate times of silicone mold.
Package of RTV-2 Silicone Liquid Rubber
Part A base silicone: 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 800g/bottle, 1kg/bottle
Storage & Shelf life
When the silicone rubber is stored at or below 25℃ (77℉) with the original unopened containers, Silicone Base and Curing agent have a usable life of 12 months from the date of production. After 12 months stock, please use the Stir machine to mix the Part A silicone for some minutes, then the silicone can be used again, no influence for other performance.
