DoubleT Posted March 24, 2017 Report Share Posted March 24, 2017 Anyone have any experience with the System Three syringes that are sold at Woodcraft. They are listed as epoxy syringes but I notice that they have the black rubber seal on the plunger. It doesn't say in the details if the seal is silicone or not. The salesperson couldn't tell me either. I wouldn't think the seal would contain silicone. I would like to leave the syringes stored in the tops of the envirotex containers like many of you folks do.

benton B Posted March 24, 2017 Report Share Posted March 24, 2017 I would go to mud hole and get the syringes made for rod finish. Quote Link to comment Share on other sites More sharing options...
MonteSS Posted March 24, 2017 Report Share Posted March 24, 2017 Get a digital scale for $10 Quote Link to comment Share on other sites More sharing options...
BobP Posted March 25, 2017 Report Share Posted March 25, 2017 If the epoxy company sells the syringes for use with epoxy and the plunger gasket looks like black rubber.... I bet that's what it is. If you're feeling hinky about it, drop a note to System Three and ask. 1 Quote Link to comment Share on other sites More sharing options...

That sounds like the best thing to do. I found some in the mean time that are 10 ml in kroger pharmacy that dont have the silicone seal that I am going to try.

I weighed the two bottles that have the same amount in them and one of them weighed right much more than the other.

I called and talked to a "technician" and they seemed to know about as much about the syringes as i did. They couldnt tell me if it contained silicone or not.

StriperCandy Posted April 1, 2017 Report Share Posted April 1, 2017 What's this about storing the syringes in the tops of Envirotex containers? I'm tired of pouring it into cups, syringes would be neater! Quote Link to comment Share on other sites More sharing options...

I'm tired of pouring it into cups, syringes would be neater! The tips of the nozzles are tapered, so if you drill a hole in the top of each bottle that is just larger than the tip, but not as large as where the nozzle enters the syringe, you get a friction fit. That way you can leave the nozzle in the top of the container, and just hold it tight to the bottle, turn the bottle over, and suck however much you want to mix into the syringe from the upside down bottle, and then turn it back over, set the bottle down, remove the syringe, and squeeze out the material into your mixing cup. When I used a lot of E tex, I used the syringes, and could just mix a little more if I ran short while coating. It is very convenient.

I weighed the two bottles that have the same amount in them and one of them weighed right much more than the other. You are correct and one of the reasons why I have long believed that ratio dispensing isn't the factor for improper set up on epoxy as frequently as many believe. This has been mentioned a few times over the years but you have guys using scales . With the correct information one could do the calculations to determine accurate weights but I don't think it is needed (well I do but for another reason below). The few I have spoken with will it works for me approach which is fine and more important a key observation. We know the scale will result in incorrect proportions (if no calculations are being done) and most that have used epoxy for any length of time know you have to be "sloppy" with dispensing volume to have issues. Most are dispensing "approximate volumes" and have no issues. Based on experiences and information from others we can be off a certain amount and still have the epoxy work. The important thing to remember this is chemistry and for the reaction to occur optimally the closer to the equal volumes the better. It directly translates to the performance of the product (physical properties of the top coat). We can be off on our mixture a certain percentage and still have a hard top coat but not the technical specks given by the optimized procedure. Best bet to achieve the optimal properties is to use volume method and measure using a a method one can negate volume loss on transfer. Syringes are the easiest repeatable method that is economical. Now you just need to mix well..... 1 Quote Link to comment Share on other sites More sharing options...

MonteSS Posted April 1, 2017 Report Share Posted April 1, 2017 (edited) As stated I use a scale and get a (what seems like) good cure every time mixing 9g of each. I did notice I am using more hardener than resin by looking at the half empty bottles. I think I will try 9g resin to 8g hardener by weight. As I said works for me and very easy to do with no mess or cleanup. I reuse the cups and stirors many times.

AZ Fisher Posted April 2, 2017 Report Share Posted April 2, 2017 I'm with you, Montee. I know you're supposed to mix by volume, but I weigh mine and it works for me. I read somewhere the ratio was 10 parts resin to 9 parts hardner, similar to Montee's ratio. This is what I have used for several years with very few issues. I use a Harbor Freight scale($10) to weight the ratios and Walmart's 30/ $1 cheapie brushes for application and this works well for me when using epoxy. Nothing beats KBS dipped and then on a turner, killer finish. Quote Link to comment Share on other sites More sharing options...

Lots of threads on the site regarding various methods "tap the can", bloxygen, and xylene usually the three main topics with this stuff.

Andyco Posted April 3, 2017 Report Share Posted April 3, 2017 Ok newbie here so please enlighten me as to why I shouldn't use a syringe with a rubber end. Quote Link to comment Share on other sites More sharing options...
DoubleT Posted April 3, 2017 Author Report Share Posted April 3, 2017 Its my understanding that the silicone in the rubber seal doesn't agree with the solvents in the etex and can possibly cause some issues with the epoxy setting up or fish eyes.

That's why I use Flex Coat syringes. They are made for epoxy, and are silicone free. Quote Link to comment Share on other sites More sharing options...
