Anybody ever use this stuff?

[RR_Mel]

I’ve been casting parts and figures for years using two part resins and two part silicone molds.  I started out using Micro-Mark then went to Smooth-On, I switched to Alumilite because it is available from Hobby Lobby and now I can buy it locally as needed.

 

All of the above have always worked great for me.  I made molds of every Rivarossi Cab Forward detail part for restoring clunkers off eBay, I’ve restored 19 Rivarossi Articulateds.

 

The casting detail of resin parts is extremely good.  I’ve reused the molds dozens of times without any loss of detail, some molds over 50 times.

 

I buy a lot of detail parts to use for making molds for all kinds of goodies for my layout.  I don’t use the purchased parts I store them for future mold making if necessary.

 

I make single, double and triple part molds easily using Alumilite Silicon Rubber Mold.  I’ve made over a hundred figures for my layout as well as fence posts, doors, chimneys and park benches.  

 

 

My castings are better than my painting skils.

This stuff is just repackaging of stuff out there.

 

Umm,

Which stuff is this stuff?

The Stuff I got from Amazon performed very well and I'm planning to use more.

The Stuff that the OP linked to, which is four different products so I really don't know which one he is talking about?

Or the Stuff from Micromark?

Generally, any of these outfits that are bottling latex or resin or silicone into one or two pint bottles IS repackaging larger quantities from other sources.

The Stuff I have is made in Macungie, PA by a 120 year-old company, Smooth-On

Just wondered.

I've used several types of mold making 2 part silicones and RTVs.

Most recently, this:

https://www.amazon.com/Smooth-Silicone-Making-OOMOO-30/dp/B004BNF3TK/ref=pd_sim_201_1?_encoding=UTF8&psc=1&refRID=H38Y95NACSS1VC8BP8H7

I like it just fine. This outfit has several varieties with different properties. Sounds like the stuff you are looking at is for a one-shot pour. With the silicone molds you can make dozens before the mold even begins to show any signs of wear.

I have some that are over ten years old and still good.

The Micromark stuff is good, too. Maybe at a little higher cost.

Once you pour it over your master be sure to tap it all around to help release trapped air bubbles.

I have used various resins, plaster and sometimes floor leveling compound (Durham's Water Putty) to make the castings with, depending on my needed end results. For concrete/stone work plaster is probably best.

Good Luck, Ed

 

This stuff is just repackaging of stuff out there. By the way, this company is one that was on the TV show The Profit, and as with all in that series there were issues with the company, don't remember if they were fixed.

I was going to cast a tunnel portal. I'm using the "Perfect Cast" plaster. I'm not using the mold material. I was wondering if the "Perfect Cast" stuff is better than plaster of paris or if it was more like Hydrocal.

 

Well, I guess I'll try it & report back in a few days.

No, but a quick read shows that they say the molding material would crumble after one or maybe a few castings. Make sure that works for your plan.

Looks interesting.

I have not used it. What are you planning on using it for?
