Hey everyone, First of all, I know this isn't an EC product, but I am in Australia and would literally have to mortgage my house to get hold of Easylease here. I have recently purchased a gallon of Frekote 700-NC, making the switch from wax and PVA. As this is my first use, I am a little bit nervous about it. I have put a lot of time and money into the tools I am using it on, so I don't want to lose them. Now my issue is that I have followed the application instructions to the letter, but I am not sure if the stuff is working. I applied the first 2 coats by wiping it on with a cloth, and then leaving it to dry for half an hour. It was only when I went to buff out the streaks and couldn't do it that I did a bit of a search and found that I should be wiping it off again as soon as I see it start to evaporate. So I did another 6 coats using this method. I then let it cure over night, which is much more than the instructions say I should but I wanted to be sure all the solvents were gone. However when I tried the 'tape test' as shown in this video: https://www.youtube.com/watch?v=Nw4V-CxdXAkThe tape stuck to it as it normally would. It was possibly a little easier to pull off again, but that could just be the polished surface of my mould. It certainly didn't work the way it does in the video. This has me a little unsettled because my supplier said that when he uses the stuff, not even the vacuum bagging tape will stick to the surface. It certainly sticks to the surface of mine... Any ideas? Will I still get a release? The mould is made of Airtech Infusioncoat epoxy gelcoat, and was sanded up to 2000 grit and then polished to a mirror shine. The Frekote had never been opened before. Thanks for any help, Martin.

Hi, if you're worried about loosing the mould then do a test on a separate mould first, flat 300x300 square or something like that.
You don't typically have to buff the semi perm release agents as this will remove it. If you're getting streaks then the mould surface or tissue may be contaminated or you are applying too much in one go.
Chris
edit: I tend to apply the bagging tape before I apply release agent as I know then it will stick and seal correctly, although you do have to ensure you allpy the mould release right up to the edges or the tape

Have you used the mould sealer? On an epoxy, vinylesther or polyester surface you should use it. The NC 700 is one of the best release agents I know. It is that good that even the tacky does not stick well on it.

No I haven't, I was keen on buying it but I was actually talked out of it by my supplier. He's the Henkel distributor for Australia, but he said he doesn't use the sealer himself. It's too expensive for low quantity production, even on a full Boeing production line one gallon would last a year. He said as long as my moulds aren't too porous, there is no need for it. After chatting with him last night, he thinks my release will still work. I may have done the coats too heavy, so I've actually got a bit of residue build up that the tape is sticking too but shouldn't cause too many problems with release.

Doing Frekote by the book means using mould cleaner, mould sealer and then the release. Especially on a new mould. I know the sealer costs a lot so you really need to find a supplier that will sell it in smaller kits. I also know the frustration since my supplier only sells it in a 4 gallon can even though Frekote makes a 1 pint can!!!!!!! Arghh. PS, I am also in Australia

I personally use, albeit on carbon moulds. 1 coat chemtrend mono coat 4 coats freekote Cure at 60 degrees for 10-20 mins Let cool 2 coats freekote Cure at 60 degrees for 10-20 mins Let cool 2 coats of freekote cure at 60 degrees for 10-20 mins Let cool Then 1 final coat of freekote Not sure if it matters but I work with pre-preg But that's just my method. Works every time never a problem.

For what it's worth, I didn't have any issues at all with the release. My part slipped out of the mould like butter. It does have some residue on it that I'll need to polish out, but it seems the issue was that I applied the coats too heavy. Didn't cause any problems with release, so I'm pretty stoked with the performance of the Frekote.

Well that's interesting! Do Nuplex sell the smaller quantities of Frekote, ie. 1 gallon? How much do they charge? I had sort of dismissed Nuplex for any of my supplies as they typically only deal with quantities far larger than I will ever need.
