Ric670 Posted August 8, 2010 Report Share Posted August 8, 2010 Can anyone out there tell me why i am getting a milky residue on my silicone mold? I tried to make a mold from the alumilite 3 i let it cure its alotted time, and when i tried to make some swimbait molds like the newest one i have posted in the gallery (bluegill swimmer) i get what i can only describe as dimples. Any help would be greatly appreciated. Rick Quote Link to comment Share on other sites More sharing options...
JoeDobs Posted August 9, 2010 Report Share Posted August 9, 2010 I have made a few rtv molds myself. All of them seem to "sweat" a littlebit. I was told by Alumilite that it is the oils in the rtv "sweating" out. I thought that maybe I hadn't mixed the rtv enough, but it looks to be a common thing. I did some searching and found that some people will throw their mold in the microwave for a few minutes to get the oils to come out. I put mine in the microwave anyhow before my first pour, and then take a soft lint free towel and wipe out the inside of the mold cavities. I haven't had any problems with dimples since I started doing this. Hope this helps Joe Quote Link to comment Share on other sites More sharing options...
