Tin Cure Moulding Liquid Silicone Rubber RTV2 for Plaster Ceiling 20 Shore A


Product Description

Tin Cure Liquid Silicone rubber is is generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2% curing agent, they can still be operated within 30 minutes, but will be formed after 4-6 hours. With resistance to deformation, high temperature, acid and alkali, and expansion.

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.
