Abstract
Acetone (CAS No. 67-64-1 Acetone ) has been replaced by dibasic esters for cleaning tools and moulds for polyester casting.

Description of the substitution
When casting in polyester there is a need for cleaning tools and moulds. Earlier acetone (CAS no 67-64-1 Acetone )allmost allways was used for this cleaning. Smaller moulds and tools can be cleaned with a solution of dibasic esters instead.

The example includes
Safety and health at work: Yes
Environment: -

Technical requirements the product must fulfil

What problems made you look for a substitution?
The use of an organic solvent - acetone

What substance or product did you use before?
Acetone

What solution did you find?
Instead of acetone you can use a solution of dibasic esters like Fantosol BME-1 (Sveda kemi) or DBE (Brenntag Nordic)

Assessment of the solution
Good. The use and the evaporation of acetone was reduced

 

What other solutions did you try/assess?

 

Further information or literature
Not all cleaning jobs in connection with polyester casting can be performed without acetone. F.ex. when cleaning big moulds acetone is still used.
