Im currently trying something new. VYTAFLEX 40 a urethane rubber.
WOW. This is an entirely new animal.
I would NOT recommend this product for complex sprue molds. Its like pouring thick honey. It does have a 30 minute pot life and a 16 hour cure time. So tomorrow I'll know what happened.
If you must use this product for a sprue mold, make sure the channels are large. Also...I needed a straw to gently help the flow of this product through the mold. I would recommend this product for SMUSH molds over SPRUE molds.
Im not sure how it will cure or how it reacts to color. I tinted the pour yellow. We'll see how or if this translates into a yellow cast or not.
The one thing I am curious about is...I have a Membros Hydrapipe mold. So I filled it to see if it will work and how durable it might be once cured. If it works...it could be a viable option.
I should maybe consider a Parts Package. Where I package up various parts and sell them together. Would make shipping nicer for some of you...keep what you need and trade/sell the rest.
We'll see.
