Thread: resin question

It will bond just fine.. especially well if you pour while the first one is still tacky.
But it will bond either way

Depends somewhat on what resin you are using.

I assume you are referring to polyester resin?

If so, the 2 polyester resins I use are Barnes Qulaity Casting Resin and Clear Casting Resin.

The Clear Casting Resin is no problem, do the second cast (ribbon casting?) as soon as you can to give maximum bond between the old and new. If ribbon casting, the earlier you do it also aids in shaping the ribbons, so do it as soon as you can cut and handle the ribbons.

The Quality Casting Resin contains a wax additive, you see this in the can, and it isn't nearly as suitable for this purpose. I have done ribbon casts with QC resin that worked perfectly OK, but others delaminated on the glossy side of the ribbon (where it was pured on the glass/mirror), came apat very cleanly

If you are referring to some resin, sorry can't help you.

It will bond just fine if it's just resin.

However, as stated, if it has surfacing wax in it or it is added, it will not bond.

ok thanks guys .
the reason i ask is because after turning an acrylic blank there is a great pile of curly shavings on the lathe bed and i thought why cant these be cast back into another pen blank.
seems to me that when making a pen 90 percent of the blank ends up on the floor under the lathe and the drill stand and we are supposed to be recycling stuff when we can for the planet .

Yep, works like a charm, have done several blanks with the shavings but haven't made a pen with them yet.

Have several large plastic boxes with different colour shavings waiting to be used.

The ones from the metal lathe are particularly nice

Very Very Strange. I was only asking a friend on mine the same question myself so I am interested to hear what others have to say.

Cheers Ian

When re-casting shavings, the color is quite washed out. It isn't as brilliant as the original blank. At least with the PR shavings...

PS I have also saved shavings/sawdust from some of the more showy woods like Osage Orange , Ebony etc. to use as fillings or experiment with casting in the future. Amos

I should have mentioned just plain PR, too.. .but I assumed (since we're
talking about casting blanks) that this was the case. Sorry..

Yeah I tried one once and the result was pretty ordinary. Still, may be some ways of producing a good result.

Hello London88, I am now on the IAP, so feel we know each other. I am based in Thailand, and need to know , the best source of supplies, in your humble opinion, to get casting polyester for myself, please, dontheturner.

Hello Don!

I don't have any information on suppliers in Thailand, but if you can search for either
manufacturers or distributors online, they should be able to direct you.

I've found that if you can talk to someone at the manufacturer ("accidentally" talk to
a chemist? ) they might be able to direct you to local trade organizations or suggest
the types of businesses that use their products. that can often lead you to someone who
might take a few extra moments to help you get to where you want to be. It might help
if you have a name as a referral.

If you can find someone who makes kitchen or bathroom counter tops, they might allow
you to buy a small quantity from them. They probably buy it in 55 gallon drums, and
might go through two or three of those before lunch.

We're just not in the same league and don't spend enough for them to take the time to
talk to us. So .. like anything else, it's 'who you know' that can help you. And if you
find someone local, bring a pen .. spend some time with them if you can. Listen watch
and learn .. you might pick up lots of helpful information just by seeing what goes on
in their operation. And once you know each other, they're more likely to understand
your questions and needs.

If you can get a hold of some Tech Sheets from different manufacturers (many are
available online) then the people you talk to will be more likely to understand what it is
that you're looking for.. and perhaps they can find a suitable replacement locally.

I wish I had an answer that included a local phone number and product name .. but
I don't know anything about the market where you are..

Hello london88, You woke me up to the fact - you mentioned in your para 3 - There are NO kitchens manufactured here, in Corian - simply because kitchens are very very 1940's. - leastways they are as far as us Westerners are concerned. it is a bit like glue. Sure you can get the ''pear-drops smelly'' type glue, and also the white normal latex. but i am buying various glues, like Titebond for my normal wood jobs, and for pens, the two part epoxy, from the UK. They are not allowed to even airmail items classed as chemicles, so I have to get a mate to ship them to me. So maybe I shall have to find someone, selling BLO as well. then order. I never conected, until you said it.''Kitchen tops'' then I realised! dontheturner..

Let Google do the walking, there is at least one manufacturer of polyester resin in Thailand

Thai Polyset. High Quality Polyester Resin

so a more thorough search migh find others .

The above may be able to point you in the right direction?
