rico.29 Posted July 29, 2005 Report Share Posted July 29, 2005 Hello, as i'm a biginner in molding an pouring, i would like to know if i can use the same RTV silicone as the one i've made my mold of. do i have to had something to extract the lure easily? I don't know if it's possible but i would like to make lure with RTV silicon, i think lure should be more resistant than with plastic, but how about swimming? Has anyone of you ever try to make is lure with RTV silic.? If so let me know your advise. Thank you, Eric. Quote Link to comment Share on other sites More sharing options...
Mattlures Posted July 29, 2005 Report Share Posted July 29, 2005 Dont do it! you will destroy your mold. Silicone will bond to itself. The mold needs to be a diferent material. Quote Link to comment Share on other sites More sharing options...
rico.29 Posted July 29, 2005 Author Report Share Posted July 29, 2005 Thank you Matt, so i guess i've to buy soft plastic instead of silicone : i've been told that if i pour my mold with talc it should work? is it true? Is there other product i can use instead of silicone (and soft plastic as it is difficult to buy it where i live) to make soft lure (as shad)? Thank you.

rico.29 Posted July 30, 2005 Author Report Share Posted July 30, 2005 i have found RTV/HB silicon, i was thinking to make my mold with it but i'm wondering if i can pour hot soft plastic in it? will the lure extract correctly without adding any product for a better extraction? if so what kind of product is the best? Thank you. Quote Link to comment Share on other sites More sharing options...
redg8r Posted July 30, 2005 Report Share Posted July 30, 2005 Hi Rico, Matt is correct to an extent, its always a good idea to avoid using silicone to silicone, it readily bonds to itself even after cure, ive stacked a couple cured molds on top of one another to find them joined a few days later. However talc & other designed mold releases will help tremendously. Anyone that makes a 2-part silicone mold needs to know that you have to use a release between pouring the 2 halves to prevent bonding. A few of options: 1) Mann's makes a variety of releases for RTV I use the 800 universal & it works well. If you talc or lube the mold VERY well you might get away with it, but if you ever miss a spot, your RTV mold will most likely be trashed. 2) If you're nervous about destroying your existing RTV mold, I'd recommend making a positive cast of that mold & duplicate it in urethane or polyresin, then use that new mold to pour your RTV baits from, a good result from using this method is that you wont need any future mold release. 3) consider casting (pouring) with urethane rubber instead of RTV silicone. its cheaper & they make shore ratings in the same neighborhood as RTV. I'm almost sure that RTV silicone releases naturally from urethane rubber, but someone please correct me if I'm wrong. Quote Link to comment Share on other sites More sharing options...
