I dont know if you will be able to help me.
I need a jelly compound which is soft to the touch but when it comes into contact with the atmosphere i then want it to start to go very hard within 30 mins.
The best way to explain is to think of a jelly compound in a sealed tub so it will stay soft for up to 3 months or even longer. I then want it to be opened then to start going hard within 30 mins.
Can you help with this or so you have any idea who can help me?
Thanks for reading...
