Trial Number 1

Trial Purpose:

To replace MEK for removal of nitryl rubber or a butyl based rubber.

Date Run:

08/13/1998

Experiment Procedure:

SUBSTRATE MATERIAL: Steel
QUESTION ASKED: Trying to replace MEK for removal of a nitryl rubber or a butyl-based rubber. What are the possible aqueous cleaners that could be used?

Trial Results:

RESPONSE/ANSWER: In 1998, the Massachusetts Toxics Use Reduction Institute (TURI) will publish the results of the tests conducted at the Institutes Surface Cleaning Laboratory (SCL) in a searchable database/spreadsheet format. This should make alternative cleaner selection faster and easier. Even though the results listed below do not all relate to the rubber contaminant, some of the adhesives and coatings are very similar in their makeup. Here are the results of your query, based on the information supplied:
