Instructions for RTV-2 Silicone Rubber for Pad Printing
Preparation
Prepare the silicone pad mold, clean the pad mold with detergent, dry it with air gun, then brush a layer of release agent, and dry it again.

Mixing
Please weigh 9 gram of part A base and 1 gram of part B curing agent part B 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 part B is 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 35ºC(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 as soon as possible onto the original, avoiding air entrapment. The catalyzed material will cure to a flexible rubber within 6 hours, we advice you de-mold after 24 hours, it is will improve the printing times of silicone pad.


Attention of RTV-2 Silicone Rubber for Pad Printing
Please accord your product's size, letters to choose the right hardness silicone, and you can add some silicone oil to adjust the hardness.

Storage of RTV-2 Silicone Rubber for Pad Printing
When stored at or below 25 C (85F) in the original unopened containers, Silicone Base and part B Curing agent have a usable life of 12 months from the date of production. After 12 months stock, please use the Stir to mixing the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.
