Trial Number 0

Trial Purpose:

Ways to clean materials sensitive to water

Date Run:

01/23/1998

Experiment Procedure:

This is a call to any and all who may enlighten us as to the best way(s) to clean materials that are sensitive to water. At Hughes ELCAN, we manufacture many opto-mechanical devices which use a variety of different materials. We are looking for a system that will clean lenses with stain sensitive approaching 51, 52, 53. A few of these are listed in the chart below:

Description Acidic Classification
FK 51 51
SK 10 52
SK 15 52
SK 16 52
BaSF 50 53
KZFSN4 53
QUESTION #: 1
SUBSTRATE MATERIAL: Glass

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. Here are the results of your query, based on the information supplied:

The best we can offer are SCL’s test results on the substrate of optical lenses (all proprietary manufacturing information is deleted from the database). They are as follows:

SCL # Substrate Contaminant  Mechanism Cleaner
95‑409‑01‑2* GLASS WAX ULTRASONICS OAKITE
95‑409‑02‑2 GLASS WAX IMMERSION ALCONOX
95‑409‑03‑2 GLASS WAX ULTRASONICS ALCONOX
95‑409‑03‑2 GLASS WAX ULTRASONICS OAKITE
96‑435‑01‑8 GLASS ROSIN IMMERSION OCCIDENTAL CHEMICAL
97‑550‑01‑3 GLASS GREASE SPRAY ALCONOX

97‑551‑01‑2 GLASS POLISH ULTRASONICS OAKITE

Success Rating:

Technology Transfer.

Conclusion:

Cleaning projects vary from case-to-case. The database does not have a searchable category for ‘water-sensitive materials’. To obtain more detailed information about any of the listed trials, have the SCL # ready when contacting the lab at (978)934-3133.

ADDENDUM: This question and response have been submitted to Precision Cleaning Magazine for publication in the February issue.
