I just got my first gallon of Silmar this week, and I've already played with it- I like it MUCH better than Castin' Craft! :)

But the gallon can is a bit awkward to pour from while it is full (which won't last long...) but for every 3oz cup I mix, I seem to get about a 1/2oz on the floor- UGH! Waste waste waste...

I store shellac in cleaned out box wine containers- 1 with an aluminum bag, the other with a poly bag. Airtight, easy dispensing, works well for shellac.

Would it also work for PR?

I don't mind trying to find and purchase metal cans (like Castin' Craft comes in) to transfer out of the gallon can into a couple of smaller cans- but if I can reuse the wife's empty box wine containers....not only am I recycling, but being cheap too...lets me buy more Silmar!!! :biggrin:

I pour from a 5 gallon container and have never had a problem with spillage. Maybe transfer the silmar-41 PR to another container, I've used recycled plastic milk jugs. Or you could use a funnel and transfer to a large cup that holds the amount you will pour. Just make sure you keep the stuff in a cool place when storing, it will extend the shelf life.
 
Hello, I use old laundry soap containers and cut off the top to use it to mix my polyester resin for my blue jean blanks.It won't melt as some plastics will with polyester resins,this is how I was going to try and do it when i pull the trigger on a 5 gallon batch.I wonder if one of those tide big giant containers with the pour spout would work then you could just open it up to dispense what you needed,HMM.Good Luck,Victor
 
I too buy it by the 5 gal. and the bucket is a bit of a pain to handle. I would like to find a valve type spout that would screw on to the top of the pop out spout. Any ideas instead of transferring it into smaller containers.

West systems has pumps for epoxy that could be used. They fit into gallon cans and are consistent for hand dispensing of thick liquids -- there are also chemical transfer pumps available in small sizes -- spillage vs cost tradeoff here. Most transfer pumps I have seen/worked with are for 55 gallon drums -- and that is a lot of pen blanks!!!

I did some internet searching and found the following links for dispensers. It is by no means inclusive but I think for the convenience, I may purchase one of the plungers.

I would be a little weary of pumps with polyester. They are designed for epoxy different resin. I know that P.R. is harsher than epoxy. Heck you got to be careful what you put it in. Put P.R. in the wrong plastic cup and it will eat trough it put epoxy in the same cup and no problem.

A simple on/off lever valve would be a good solution. I have seen similar valves on cleaning chemicals with wide mouth caps. I would like to pick up the 5 gal pail put it on a cradle open a valve and pore. Then return up-rite when not in use. The pumps are a bit pricey also. I haven't had much luck searching for such a thing.

It seems like Alumilite sells the same one that Woodcraft does in single units at a good price. I use them to dispense Alumilite.

Hijack alert !!!

This does not have anything to do with this thread, but the fellow who owns the above business and I went to the same race car building school back in the '80s. Was supprised to see the link.
 
I also buy the 5 gal. buckets of silmar and use a turkey baster with a squeeze bulb until it gets about half full, then i tip and pour. I just make sure I let the baster sit in the hole for a bit to let the residue drip out before I cap it all.

That's a pretty good idea. I still like to find a cheap on/off valve I could screw on and leave it on. I will keep looking wile I am about. I seen what I want in Home Depot paint department but it fits a large mouth cap and wont fit.
 
I went with the 'smaller container' solution. I held onto the 1 gallon Silmar tin, and the
one gallons is easier to handle than the 5 gallon, obviously. I picked up a couple of
quart sized squeeze bottles and caps. Makes it much easier to control, especially with
Alumilite. When you stop squeezing, the resin stops coming out as it sucks back in air.
Much easier to weigh it out instead of "6 more grams of part A .. oops, 4 more grams
of Part A .. oops .. 3 more grams of Part B ..."

.. not that I've ever done that..
 
Like Freddie said one gal. plastic gas cans. I went to wally world and bought 5 for less than $15 with spouts, Been using them for well over a year and spilled less than 8 oz. in that time. I tried using the 1 gal tide containers worked well for about 2 weeks and then the PR had lunch on the spigot lost about 1/2 gal.

So the PR will not eat through the GAS Can? If that is the case, it sounds like a good solution.....

Why not a handy item like this?

Very easy to do, we had some of these when I used to work in carbon fiber fabrication. Not sure you can find them to buy, but they are easily made. Just tip it until you get a very small, easily controllable stream. Works a treat as my english friends would say!
 
I wonder if the Alumilite plastic bottles will hold PR. For some reason I have been saving all of the plastic squeeze bottles I get from them

Justin that pail tipper is nice BUT still have the problem of control till the can gets almost 1/2 empty. That would be ideal but still need a valve.

Not really...you can get a very fine stream tipping it to just the right angle. It's really easy to do once you get it down a few times. It's not like we're doing titration anyway! :biggrin:
 
I've got a 5 gallon pail of silicone that I just put up on the counter, take off the cap
and tilt it into the mixing bowl. When I get enough, I tilt it back up and use the edge
of the bowl to catch any drips. Haven't lost a drop yet.
Then again, it's silicone. If it starts to drip, you've got about 5 minutes to catch it
before it actually hits the ground..

PR works just the same. The jig I posted just makes it a lot easier. Oh..and you just have to be a wee bit faster than you do with silicone!

Yeah.. but I have no trouble with the 5 gallon pails..

.. but I cannot pour the activator without spilling it.. even from that
small bottle. Go figure.
 
I use very little and buy the gallon cans. I leave that little metal stopper in place and just poke a hole in it. I use a punch and a hammer and put about a 3/8" hole in the edge of it. It works perfect for pouring small amounts.

I got it that's a good tip leave the stopper in punch the hole in that. Than you can still cap it for storing.

You certainly wouldn't want to punch a hole in the cap. Just wanted to clear that up :wink:
