Brilliant, does polyester cure hard? I'm wanting to cast my own blanks to create my own material for pipe stems. I do use the acrylic blanks that are made for pens but not sure what type of resin is used to cast those, polyester or lucite. Thanks 👍
I think that’s interesting I’m also into fountain pens and traditional WetShaving. I find people that are into traditional WetShaving also find themselves going in to older things or older style things like fountain pens, typewriters, wax seals for their letters,Things of that nature
Would the Silmar 41 resin be comparable to the Castin Craft Polyester resin? Castin Craft is really expensive where the Silmar 41 is priced much more reasonably. A gallon of Silmar 41 is about the same price as a quart of the Castin Craft resin.
@@FrickWerkz Thank you, I'll be buying some. Even with the hazardous material charge and the shipping charge, it's still half the cost of Castin Craft!
@@FrickWerkz That's awesome. I sent them an email about the cost of shipping to Western NY and what if any hazardous material charge there will be on a one gallon shipment but the prices are great! Do they sell anything similar to the Alumilite Clear Urethane slow? I saw epoxy resin offered but nothing that said "urethane".
@@robh063 No, these guys are just a jewel in the rough for the Silmar41, their main business is bar top coatings, surfboard and boating applications, and generally commercial at that.
what are these droplets that you put into the epoxy? is this alcohol-based additive that makes the epoxy bubble? how long does it take for your epoxy to settle? when I mix mine, it's settling for such a long time that all the colours melt into one bleeeeh, instead of just nicely mixing together...
So this isn't an epoxy, this is a polyester resin. Typically you have one of three types of resins - this type that uses a smaller amount of a catalyst, epoxy (which can be mixed by weight or by volume), and urethane (again can be weight or volume depending on the formula). Polyester resin gets hotter faster and pushes bubbles out but that can also keep the colors more separated in the final casting too. Color separation is a big "art" of the resin casting world as it involves a lot of factors to get the desired effect.
@@FrickWerkz thanks, and so what would you say is the average curing time of polyester resin compared to epoxy? let's say under normal circumstances epoxy cures to about 2-3 days to 90%. What about polyester?
If I want it really clear I use a pressure pot, if I am doing pen blanks or mostly opaque larger blanks I just let them cure. The resin will get warm and does not hard gel as fast as Alumilite does so there is time for bubbles to get out.
More catalyst and higher temps are the best tips to keep from getting sticky surfaces. Make sure it is warm when you start with it and add almost twice as much catalyst as the directions call for.
No I have not yet, got busy at my normal job the latter part of this year and I have not been posting as much as I would like or working on projects. I will definitely be posting the turning video later. Which should I turn, the pen blank or the brush handle first?
There are a lot of factors for that, temperature, thickness of pour, if you are pouring all at one time, how brittle can the final blank be? - the more catalyst you use the more brittle the blank will be. I generally use 20-22 drops per ounce on my castings.
@@sebdaems3237 You can use epoxy to make these blanks, sure - urethane will work well also. Just don't mix the chemical agents incorrectly and try something used in one resin on another.
Hi does the resin bubble up on its own or do you heat it up it looks like its boiling is it just the heat from the resin causing this? very nice though
Yes, this is a very exothermic reaction. The heat AND the cross-linking of the resin curing is what makes the resin move around like a lava-lamp before complete cure stops it. The heat is what is going to push bubbles out of the resin and allows it to cure relatively free of them.
I can just sit and watch the colors swirl. Nice blanks! 👍
Thank you! Check out my video that only has cuts of the resin cures!

Yes, I can totally see that, especially if you get into any of the Reddits regarding these type of things.
Wax seals interesting analogy
ok great lovely! do you have more info on how to build that pvc piece?

Silmar would be superior. Fresher, better product hands down a better value.

@@robh063 I just bought some and it was $61 for the gallon in total and it has shipped in only 3 days via UPS.

Are there less bubbles inside polyester resin than epoxy resin?

@@MrProvocer Polyester cures pretty fast, 1-2 hours for full cure if catalyzed correctly.
How do you cure the resin? Do you use a pressure pot? Great videos by the way.
If I want it really clear I use a pressure pot, if I am doing pen blanks or mostly opaque larger blanks I just let them cure. The resin will get warm and does not hard gel as fast as Alumilite does so there is time for bubbles to get out.
I just started using polyester resin, any tips to remove the stickiness? I have a feeling I might be doing something wrong.

@@FrickWerkz thank you so much will definitely try that
Have you turned this yet? I want to see it!

Hi ,
Nice blanks.👍 What do you add to the resin at 2:03?
Regards,
Paul.
Thank you! The addition was the catalyst that the resin uses to kick off and cure, it's methyl-ethel-ketone-peroxide.
OK Understood.
I thought it was something that created cells or separated the colours.
Thanks for the reply,
Cheers
Paul.
I want to cast a thick polyester resin,can you recomend me a good ratio for the catalyst
There are a lot of factors for that, temperature, thickness of pour, if you are pouring all at one time, how brittle can the final blank be? - the more catalyst you use the more brittle the blank will be. I generally use 20-22 drops per ounce on my castings.
Where do you sell your brushes?
I sold it where it snows
good day! can you find out where you bought this plastic?
I don't understand the question. Are you asking where I purchased the resin? USComposites.com - Silmar 41 resin.
Do you know if i can use acrylic paint with polyester resin?
I do not know, I have not tried to use it before, I would think it can work in smaller quantities since it is not water-based.
What is the product you add at 2.05?
That is the catalyst for the polyester resin, so that starts off the hardening process.
@@FrickWerkz thanks for your quick reply. Does it work also with epoxy resin?
@@sebdaems3237 You can use epoxy to make these blanks, sure - urethane will work well also. Just don't mix the chemical agents incorrectly and try something used in one resin on another.

waht else beside pearl-ex to color Polyester Resin ?? pls
All kinds of stuff, any resin specific dyes are great, embossing powder, alcohol inks, just want to stay away from water based dyes.
What size pvc pipe is that?
That is 1 1/2" diameter PVC pipe.
@@FrickWerkz thank you
