I appreciate this information. To answer an earlier question-I'm not sure what kind of silicone I have, I just pick it up at Hobby Lobby. Also, both the silicone and resin are being used in the same temperature/environment. I have no idea what the humidity is but the temp is around 76-77 degrees.
You will need to know about the product you are using or you might find this gets expensive from fails. You need to know your pot life and cure times and it pays to other details like the shore hardness, if it platinum or tin based (how forgiving it is to everything) and what percentage the cat is.
So the stuff I use is called "Vario". It is a Platinum based addition cure at 10:1. Part A comes in two types - A40 (pretty hard) and A15 (quite soft). The really cool part about this product is that you can mix the two shore hardness silicones to make a custom shore. So if you mix 1 part Vario 40 and 1 part Vario 15, you get shore hardness of about A27.5 (middle of the range).
The normal potlife is 15 minutes and the cure time is 6 hours at 25 degrees C. It might take longer at lower temps and I know it cures faster at higher temps. During a recent heat wave, I saw this stuff cure in just 2.5 hours! If it is cold, I'd leave cure for 24 hours.
If I need a faster than 6 hour cure, I can add Vario part B "F-Type" for a fast cure. Still 10:1, but now pot life is just 6 minutes and cure time is just 15 minutes. NO TIME TO DEGAS!
Like the Part A, you can mix the Part B at different ratios to make a custom cure time. With 1 part of normal Part B and 1 part of F-Type, Potlife is just under 10min and cure time is 2.5 hours at 25 degrees C. I can degas as long as I don't mess around.
So I like it because it is customizable to the job I am doing.
I discovered it in late 2014 and to date, I have mixed over 100KGs of the stuff. Yet it is the little things like what type of super glue can I use and not have a reaction? As it turns out, NO air curing products at all. Want to use super glue for a mold wall, use kicker to make sure it is cured.
