Hello,

I recently purchased the 80 D resin. After trying to pour a couple small parts (making a transducer mount for humminbird unit), I'm unable to get a quality cast. I tried mixing the product without much agitation, but I acquire a white foamy product nevertheless. *I just opened the 80D, so humidity shouldn't be an issue.

It seems that I probably need a pressure/vacuum pot. I've attached a link of one I found online (with pump included). Should this work with this product? I primarily make small repair parts for my boat, but primarily have used alumilite white for casting lures.

I'm looking to eventually try and make shelled lures using the harder 80D vs the alumilite white too.

I'm very familiar with using alumilite products, just not with a vacuum. Is there a step-by-step for using these with your product? For instance, how long do you degass for with 80D/alumilite white? Should I put the mold back in the vaccum after pouring the degassed resin in (as in a 2nd vacuum in the process)?

Thanks!

It seemed to form a bond with the Remelt material (even when using mold release). Am I doing this wrong, or does the 80D just get too hot for this?

Aaronmc,

The Amazing Remelt is for small pieces with thin cross sections. The Amazing Remelt... remelts at 130F, larger pieces will exotherm (heat up) higher than that temperature and start to remelt the Amazing Remelt. (wow, that's a mouthful) ;-) So yes, odds are it gets to hot for the size of piece you are doing Aaronmc.

Foaming typically is a lot of moisture, with a small amount you may just get some tiny porosity bubbles, but white foaming moisture is coming into play somewhere. It is recommended to degass the Performance 80D, pressure or vacuum. There is not enough open time to use a vacuum on the white, you would need to use pressure, you can use pressure on either of them as opposed to purchasing two pieces of equipment.

If you would give me a call I can explain a bit more on the process of both.

Have a wonderful day Aaronmc, hope to speak with you soon.

Regards,

Carol

Thanks Carol.

Yes, I'd love to chat more about product use and degassing.

The particular piece for the transducer was very thin actually and prone to break as a result. I wanted to use the Remelt to make a few additional "sacrificial" pieces. The amazing remelt was incredibly easy to use and the transparency was very helpful in cutting out the original piece. It would be nice to see something similar in the future with a higher melting point.

What resin would you recommend for use with the ReMelt?

As mentioned, I definitely plan to chat (probably Monday) about using the 80D and recommended degassing techniques.

Did the link I provide seem like a suitable product for this?

Thank you for the help! I love your products!
