Smooth-Cast® 325 ColorMatch Urethane Resin | Casting Quickies

[ciph3x]

Is it possible to use this method to cast food grade plastic parts?

[SmoothOnInc]

@ciph3x We only have one resin which is rated for food contact, TASK 11. Also, TASK 11 is rated for DRY food contact only

[bsdhd77]

is there an off white tint that is similar to bone or tooth color?

[SmoothOnInc]

@bsdhd77 You could combine So-Strong white with other colors to get a bone color, or use our Smooth-Cast 320. It is naturally off-white.

[MLmayko]

will this technique always prevent surface air bubbles? I'm making a ball joint doll and have made a couple with your products, but I still get air bubbles. I don't have the money to get a pressure chamber so I have to find other things to help prevent them. Are their any other techniques?

[SmoothOnInc]

@MLmayko This technique can help, as can applying a think dusting of talc (baby powder) to the inside of the mold.

[SkemeKOS]

Two questions before I buy -

1] Can I produce translucent colours with Smooth-Cast 325? I specifically need a translucent CREAM colour because I want to produce a toy(fake) wax candle.

2] Can I also produce clear colours with Smooth-Cast 325? I specifically need a clear GREEN colour because I want to produce a toy(fake) wine bottle.

If the answer is yes, where can I buy them and what are the products called?

Cheers.

[SmoothOnInc]

@SkemeKOS Yes you can, using our So-Strong colorants for urethane resin and rubber.

[wmalongboarding]

so if i wanted to make skateboard wheels or bushings i would mix the PMC-790 with the task 12/

[SmoothOnInc]

@wmalongboarding No room-temperature material will have the abrasion resistance of an industrial heat cured urethane (like a skateboard wheel), but as shown in this video - prototypes can be made using our rubber and resins /watch?v=UGnAGCROUzc

[imasian106]

when using 325 color match, is the molded model hard or flexible?

[SmoothOnInc]

@imasian106 The Smooth Cast 325 material will cure to a rigid plastic

[russianpegs]

is the urathane more rubbery or more of a plastic like substance? I was thinking of making skateboard wheels with it

[SmoothOnInc]

@russianpegs It can be either - We have many formulations which may be of interest to you for prototyping wheels. Our PMC-790 is a urethane rubber, while our Task 12 is a flexible urethane resin.

[russianpegs]

@SmoothOnInc thanks, I'll buy some and test it out

[Indigocandles]

Hi, I'm using the 325 to harden silk flowers in order to then create candle and soap molds. I used it for the first time last night and WOW, did it harden up fast on me! I only got 2 flowers done before it hardened up on me. The supplier I purchased it from told me that the 325 was probably the best I could use because it had such a quick dry time and if I used a slower dry time I may not get the results that I was looking for. Any suggs. for me that could help save myself from wasting it?Thx

[SmoothOnInc]

@Indigocandles You may want to make sure your room temperature is around 72F. A large mass of material cures faster than a small mass. A slower version of this resin may give you more time but is more susceptible to foaming due to moisture which may in the silk flower.

[sixoclocksinner]

Is this stuff good for making masks?

[SmoothOnInc]

@sixoclocksinner Generally this rigid material can be used for such an application. I would recommend a layer of fabric be adhered to the back of the mask for comfort.

[Toyman1982]

I was told that this stuff can cause Serious breathing problems if you use it more then once without a respirator (even in a room with ventilation, is this true? cause ive used task quite a few times without a respirator and i never had any problems at all, aside from normal panic attacks i have from stress (that ive been having for 15 years)

[SmoothOnInc]

@Toyman1982 Using a respirator when working with these resins is optional as long as you are in room sized ventilation. The technical bulletin and MSDS for each product provide full safety info. These documents are available on our website.

[marylcurtis]

Your 2 videos on mold making and casting are helpful. Are the products you mentioned available in local craft stores or where can I find them?

[SmoothOnInc]

@marylcurtis Mary, you can buy these through Dick Blick, and we also have a distributor listing on our website.

[marylcurtis]

@marylcurtis Thanks!

[SmoothOnInc]

You can purchase Sun Devil through Reynolds Advanced Materials in Orlando - 1-800-328-8786. Jason - Smooth-On, Inc.

[elenauful]

where can i find Sun Devil additive in miami

[SatansMullet]

How clear is the Smooth Cast color match without anything added to it? like is it REALLLLLY Amber-y? or is it clear but with a slight amber tint?

[SmoothOnInc]

@SatansMullet The clarity of Smooth-Cast 325 will depend on the thickness of the casting. I would recommend contacting us, or one of our distributors directly to request some cured sample discs of the material. - Jason Smooth-On, Inc.

[bondophobic]

ok one more thing is it UV resistant?

[SmoothOnInc]

@bondophobic Smooth Cast 325 is not, but you can add our Sun Devil additive to help reduce the effects of UV.

[bondophobic]

does this dry hard or is it rubbery?

[SmoothOnInc]

@bondophobic Smooth-Cast 325 is a hard (72D durometer) plastic once cured.

[papasitoOC]

I like that your Mold Star 15 'reflects perfect detail.' Would this be the right product to use for making candle molds? I do not use Bees Wax like Bees Kep. I use parafin wax and it's melting point is 140º (Faranheit) and 160º (Faranheit), and I do need one of your products that will cast great detail. Also can I order directly from your company or do I have to find a retailer?

Thank you for any help.

@papasitoOC Yes, Mold Star 15 would be an excellent choice. Our buy online link will guide you to the best source for our materials, just click on the BUY NOW button on the upper right hand corner of our site.

[nycrayjai]

I just demolded my smooth cast 325 without adding any color and the cast is soft? should it be soft? it feels like rubber. I used to use smooth cast 300 and it was like hard plastic. did I do something wrong?

[SmoothOnInc]

@nycrayjai Smooth-Cast 325 should set slightly harder than 300. Visit our website for tech support. You can submit a support request online or else call for toll-free support.

[tommelom2]

Where can I buy your products in Europe, or Norway to be more spesific? Can you ship from the US?

[SmoothOnInc]

@tommelom2 Visit our website for a list of international distributors.

[SmoothOnInc]

Actually this is a solid cast piece. A hollow casting can be created by using a smaller amount of Smooth Cast 325 and continuing to rotate the mold until the resin cures.

[UsaDumplingTsukino]

This piece inside the mold is hollow inside after it is out of the mold, right? I have been wondering how to cast hollow pieces, is that why you flip the mold over and over for 15 seconds also? To distribute the resin evenly along all sides of the mold?

[montazah1]

thank you from egypt very nice very good

[SmoothOnInc]

@SmoothOnInc

Wow, I have some Chavant NSP and it's no where near as soft as that stuff in the video. I thought maybe it was water clay because of that. I guess I will stick with good ole cheap foam core for now, I've even made a box mold using Lego bricks and that works pretty good too. Thanks for the reply.

[Kriterian]

Great video again, but I have two questions:

1) What kind of clay are you using to imbed the model?

2) Do you sell the plastic sheeting or have a good source for it? The stuff I find online sounds like you can't cut it yourself without a special blade, and it's fairly expensive.

[SmoothOnInc]

@Kriterian We are using a non-sulfur modeling clay. Chavant NSP is a good example of such a clay. We do not sell the acrylic sheeting, and yes it can be tricky to cut.  You can also use melamine board (available at a home DIY store in the shelving department) or foam-core board (available from most office-supply stores).

[SmoothOnInc]

@Kriterian Working under warm conditions (ie. filming lighting) goes a long way to helping the clay soften. Water clay can be used, but ONLY with platinum cure silicones.

[CrazyHorsies]

woah

[MrHorrorguy83]

Another great new video! Love the quality too, nice to see everything in HD :)
