hi ther just want some honest opinions on resin research and kinetix the pros and cons about both products thanks
My advice is if your using the same container to mix by volume is count out loud, and repeat each number until its all in. Its the worst when you forget what you put in. The ratios are important so take your time, and don’t get distracted when your mixing. Jim talks of fish eyes, but I have seen the whole darn school of fish when I screwed up.
Ghetto has it nailed, every time I have had a problem with epoxy’s, I f-d up, nuke both parts and get a nuclear reaction, get distracted and use 2 parts activator to one part resin, wife used my brush to paint latex, then put it back, got a gazillion fish eyes with micro specks of latex in the bottom of each one
One's called resin research, one's called kinetix. There's another brand called "the search function", which is helpful too.
already done the search function buddy i just want the pros and con of both any help would be much appreciated
Tried both, and both seemed very similar. Additive F makes the resin easier to sand though.
Kinetix sands well , no additive needed......also bonds with polyester very well......
So all the research i have done shows me either way there both good, going to get two 6 litre kits of resin research and see how it performans.
Micah… Try everything your self… analize what it does and how it works…
look at in use for 6months, then 12 months then2 years… see if its what you want for your customers…
i find in the surfboard making game people use what makes things easy… often not what gives the best product…
xylene and parrafin wax makes it easy to get a thinner flow coat, the resin runs nicer and the parrifin melts when sanding to give some lube and make it seem to sand better...
but what does xylene do to the structure? at a moleculer level xylene never becomes part of the epoxy chain, so when it evaporates it leaves little microscopic pores and holes all over the then solid resin.
like religion you should never just believe what your told or just read.. you need to find out the principles, mechanics and science behind it..
Thanks dave appreciate your advice
The only problem I have had with Resin research is some yellowing. It was early on in the formulation, and could have been operator error. As long as you measure it properly you will get good to excellent results. Resin research sands just fine with out Additive F. I haven't used Additive F in years. I personally think issues come from Additive F. Not the product, but once again operator error. Meaning: either they keep the additive F in a sweatty tin can, or a rusty tin can. or it just gets old and lumpy. Then you add it to the epoxy, and it's all lumpy and bumpy. The pure epoxy works and flows fine with a little warmth to the batch.
Resin Research is the epoxy resin for surfboards that all other epoxies want to be. Its No.1 because its the best. I believe the biggest problem RR has ever, or ever will,have is operator error; people don’t like to admit when they do something wrong, so they blame the resin, mostly because they didn’t mix it properly.
Get a scale!!
Also, make a table of resin and hardener amounts at half oz increments using .45 to 1 oz ratio. (did I get that ratio right? Ain’t near my computer).

....read the label....
no scale. no complex numbers. it's not 100 to 45.
you can call me dumb all day long. 2 parts resin, 1 part hardener. I read that on the label. you did read the label before you started....right...read the label.
I'm so f'ng dumb i've never had a batch not cure...not gummies...no soft resin or not so complete cure...no hot box or other half baked ideas....nope...i read label before i start project.
Ray, by weight or volume? Maybe a silly question, but some guys use a scale, some go by volume. I hope to give it a go towards the end of the year, and want to be sure!
I measure both Kinetix and RR by weight and have had no problems, here’s the RR mixing ratios -> http://www.resinresearch.net/id8.html
Whether you mix by volume or weight makes no difference as it should be the same, I like by weight as I can use any old container and just pour some in, calc the weight and tare the scale for the hardener amount and mix it.
I find RR a nicer resin to work with than the Kinetix though and easier to sand with the add F, that’s just my choice of course, both work fine. If I were asked to back up my reason for why I think RR is a better resin it would be because RR have been at it a lot longer than most (for surfboards that is).
OK, boys. We are all above average. You can mix 2:1 by volume or 1:.45 by weight using a scale. Both are correct. Higher strength results when the chemistry is “more correct”. Not sure i can spell it without ‘spell-check’, but there is a stochiometric relationship that must be met for the greatest strength such every R molecule gets an H molecule to bond with. Or something like that. I was not allowed to graduate until I signed a release form promising to never practice chemistry where people’s lives depended on it.
Before I bought my scale I did just fine eye balling it. But after I got the scale I tried a little experiment. I used a couple of those clear cups with the oz marked on the side and filled them 2 and 1 oz. Then weighed them. I wasn’t as close as I think I should have been. I’ve used the scale ever since.
But I must say, I never saw Mr. GL or Davo Dietrich use a scale. But after thousands of boards lam’d, there is a good chance they had gotten the hang of it. And RR ain’t that hard to use if you will just pay attention.
