When they say "Hot melt glue" this is for a laymans comparison. The molecule chains in this stuff are massive and the result is a very hard and durable prototype. The main problem is operating temprature.
Due to the low transition temp from one solid to another and the fact that this is not a permanant state, restricts the use somewhat.
I found this stuff great too work with and had fast results. It feels like a cross between wax and rubber in its active state, and can be made into sheets, rods and balls with ease.
When it sets it is suprisingly strong and resilient. I had trouble cutting it with my sharpest knife and had to re-dope it in hot water to cut it at all.
It has great elastic properties and as such is not brittle.
In its set state it is very similar to a top quality plastic chopping board, y'know the £30 ones that are various colours for various uses. I have not tried to colour or paint it yet but I will post any new info as and when.

Plz bear in mind that I do quite alot of mould making and I use a range of materials for casts. I am happy to play with this polymorh and I think I will find some good uses for it.
