Hardener?

5 posts in this topic

I have a jug of Calhoun soft plastic that is just too soft. I think I read somewhere here recently how much hardener to add to each oz of plastisol, just can't remember. Could someone please tell me what the mixture is?

Aloha, Bill

start with a 1/4 teaspoon to 3-4 oz. of soft plastic,

then you have to use your own judgement on if its good or if it needs more or less.

Hardener must be added to and stirred into cold plastisol before heating.. 1 teaspoon in 16 oz. of plastisol will change the consistency considerably
