DESCRIPTIONSILASTIC RTV3010/3015 shoe mold making silicone rubber is a two-component material, consisting of Part A base silicone and Part B CA30 curing agent, cures at room temperature by a condensation reaction. These materials can be cast into the cured silicone mold: shoe mold making, sand casting etc.. FEATURES1. Good flow ability and long working time2. Medium hardness3. Easy de-mould from shoe mold4. Low linear shrinkage APPLICATIONSSILASTIC RTV3010/3015 is suited for shoe mold, simple products, sand casting mold making, and shoe mold by pouring way.Base and Curing Agent Mixture(100:2 by weight) in 25 C(77F) testingItem No.RTV3015Coloroff-whiteCuring agentCA30Mixing ratio100:2Mixed viscosity12000-13000 cpsPot life5-10 MinutesCuring time 4-6 HoursHardness15-18 Shore ATear Strength20 N/mmTensile Strength2.6 MpaRelative density 1.09-1.15 g/cm3Shrinkage≤0.3%Elongation at break600% How to make the silicone shoe 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, pls use a suitable mold release agent such as soap water, detergent or petroleum jellies.MixingPlease weight 100 Part A base and 2 parts of CA30 Curing Agent in a clean container. Thoroughly stir Part A base silicone before use, as filler separation may accord 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. Volume increases of 3—5 times will accord on vacuum de-airing the mixture. So a suitably large container should be chosen.Pouring the mixture and curingPour the mixed Part A base silicone and CA-30 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. STORAGEWhen stored at or below 30 C (85F) in the original unopened containers,SILASTIC RTV3010/3015 Base and CA30 Curing agent have a usable life of 9 months from the date of production. Note:SILASTIC RTV3010/3015 is an industrial product and must not be used in food molding,dental human skin molding applications.
