Hello please introduce this newbie.

 

I'm willy from Indonesia. as chemical raw material importer we are expand our market to steel casting industry as we have the hardener named *Triacetin* which will be mix with furan resin and sand as sand mold.

 

the problem is Triacetin curing time is too fast, which is 10 minutes, while foundrymen needs 60 minutes to setting.

 

is there anyone here can help to solve this problem. is the purity of Triacetin must be lesser (currently 99.75%) , if so what is chemical to lesser the purity? thanks

 

regards,

Willy
