This product is used by screen companies who use an activator - to make it go off very rapidly indeed.
The benefit is that it doesn't go hard when you open the tube - only a small amount does.
It goes off a little faster when completely exposed - when using.
But you don't get a completely wasted tube that goes rock hard as soon as opened
There are dispensers available for these "sausage packs"
