why is it necessary to soak the master model in water for 15-20 mins before duplicating?
Hydrocolloid is largely water, no surprise there right? In order to keep the hydrocolloid from drying out and being inaccurate where it contacts the model, presoaking the model makes sure it is full of water as it can be so it doesn't pull water out of the hydrocolloid or pull hydrocolloid into the model.why is it necessary to soak the master model in water for 15-20 mins before duplicating?
Never timed it. I just lut it in water when I start cutting the stuff and when it comes out of the microwave I give a shake and put it in the dup flask while stirring to temp for pouring.
Purely a one use material. Mix part A and part B, it solidifies permanently.I never used silicon. You can't recycle it like you can hydrocolloid, Right?
You can chop up old silicone and loosely fill the flask and then fill with new, that way you're not using all new every time,Purely a one use material. Mix part A and part B, it solidifies permanently.
well, it only takes shape once, you can use it many times for pouring/packing
