I like to know if there are any interests in buying plastic containers that you folks use in casting for mixing the resins and PRs? and, I also need to know that after you mix the two parts of the resins or PRs or what ever casting materials you use, how much heat is generated and I remember that some of you have expressed frustrations with the drinking cups getting melted under the heat produced by chemical reactions or the resins.
I have the opportunity to purchase containers to what ever HDPE or ACP #s that we would need for this casting process that some undertake. Since i have to purchase them in large quantities and resell them here, I need to know from those who do the casting that what are the specs. you all are looking for and would you be interested in purchasing them form me if the price would be right.
I also found containers to put the Abralon pads in, since we all know that after a while that they have been moistened and used the ink writings on them rub off, therefore making them very hard to recognize what grit you are picking form your piles to work with. I already committed myself to purchasing the large quantity and will also use hem for organizing the little parts of kits and odds and things including bushing s and what not.
for the purpose of storing the sanding pads they can be marked by a nail polish on the lid and numbered and if you make a caddy for them to kee them organized they will not get mixed up and won't break either and they are always at your disposal.
Please let me know if there interests in this idea.

Thanks for looking

Phillip,

I use plastic cups purchased at Sams with recycle code 1 on the bottom.

The temperature of kick off of the most common PR is around 170 degrees F if I recall correctly. My cups slightly deform but I haven't had PR eat through my cups since the first week I began casting.

I personally would not purchase unless there was a really good price. I doubt you can beat the price with shipping that Sam's Club can offer to me.

Hope that helps somewhat.

Fred, thank you for the info. how ever I need to know how much you are buying them for and if you the max Temp. the Resin goes up to, please?
 
Unsure how much. I only buy them in bulk and it has been too long ago.

The temp max as stated in the last post is 170F if I recall correctly.
 
Phillip , the cups you want will have a recycle code of "5" on the bottom of the cup , these are Polypropylene . It's not the heat that melts the cups it's that the cups are made of a styrene based plastic and the resin melts the styrene base .

Butch, they told me there is another product that will hold better to the chemical reaction and the heat. I am trying to find out that what is the best container to sue overall for this casting and if there are any interest among the members who do their own casting to buy the right container then I will invest in it, if not I won't bother with it. What do you think about the container for the Abralon sanding pads? Do you think that there would be any interest o preserve them so we can use them longer providing given that the darn boxes and therefore individual cost per pads are very expensive?

I'm not sure which other plastic containers are better then the Polypropylene for mixing of PR or Alumilite , but from all the castings I have made with PP pill bottles and the PP mixing cups I have used in the past I don't think there is a better plastic to use . As for the Abranet containers I really don't have an answer since I don't use it or MM for that matter .
 
Thanks, Butch, I am hoping I get soem more input form the other guys who do casting before I make any commitment on buy them, cince I have to put out big sum and I don't want to just buy them and not be able to turn them around.

Rich she sent me samples today she said that they have different material with higher HDPE no. and they would hold up better.
Maybe I need to rephrase my request. Since, I haven't gotten the PR or any casting medium I don't know the spec. data. therefore I ma asking if any one who does it can look on the label or info. sheet to see what's the Max. heat generated and what type of material for container they recommend to use then i can get the proper container and also what's the most common size ? OZ. that you guys use for the mixing 2 Oz., 4 Oz., or 8 Oz.? And, if there would be any interest to buy them form me since I have to store them or break down the packages to may be 5/ unit, or 10/unit. As, I mentioned before there has to be need for them form the members before i spend the money on them. Other wise I rather spend the money somewhere else for something else that we all can use.
 
Phil,
I may be mistaken but, I don't think anyone uses abranet wet. Perhapse you're thinking of micromesh?
I just use a squirt bottle with water or a small plastic food container for mine.

Monty, it's Abralon pads and I learned about ti here on line and Keith uses them wet and he taught me how to do it. I thought the ones who use them wet they would have hard time reading the wiped out stamp on them and this way you can mark the pad container on t he outside and set them in order and sue them in order.
