Re: Release agent questions
Forgive me, as this may sound a bit preachy/high minded. It's not intended to, but its going to sound that way I'm sure.
Lets grab this bull by the horns.
I've been on this forum for about six/eight months now and with great frequency there is someone asking about release agents. (no, I'm not picking at you in particular)
We live in a modern world where products are designed specific to an application. Pam, One Shot, grease, shoe polish, wax, and a host of other materials have all been tried/used for release agents.
Yes, they work. They will form a layer that separates the part from the resin, however they are all prone to goofing things up too. (another subject matter that surfaces on this and other forums with alarming frequency)
Albert Einstein is often credited with saying: "Insanity is doing the same thing over and over and expecting different
results." I humbly encourage/suggest guys take 5 minutes out of their day and perform a Google search on aerosolized commercial mold release agents.
Now I'm sure to get both barrels from many who say that there's nothing wrong with using shoe polish or wax, or whatever. I'll go one further to say that they'll say the guns shoot fine and there's no issue. I have no doubt they are telling the truth as I too have used the same products. (12+ years in this game)
However, there exists an intangible quality called "presentation", "fit/finish", and pride in your work that a guy at home can achieve if he's patient and diligent.
Shoe polish cannot be applied to an action without there being some swirl marks. These surface inclusions can't be felt, but you can and will see them with normal healthy eyesight. This is where an aerosol can is going to win every time.
One shot isn't a release agent. It's a lubricant designed to keep brass cases from galling/seizing in a sizing die under extreme pressure. The film thickness is heavy and this means its prone to smearing and it's not making a mirror image casting of your action. It's also possible for it to contaminate/react with certain resins.
http://mclube.com/ is where you should start/end your search for a proper release agent.
Good luck on your project.
