Compatibility Testing of Polarized
Polycarbonate Lenses with Valtron Detergents

I. Purpose

The purpose of this test was to test the compatibility of polarized polycarbonate lenses with low-foaming neutral VALTRON detergents.

 

II. Parameters of the Experiment

  1. Conditioning of the Substrates:
    Several trays of gray and brown polycarbonate lenses were submitted for testing along with a sample of PM solvent for final wiping. No further conditioning was necessary.
  2. Preparation of Detergent Solutions:
    4% VALTRON DP048 neutral low-foaming detergent
    4% VALTRON SW4110 neutral low-foaming detergent
    4% VALTRON DP95013 neutral low-foaming detergent

    500mL each of the above detergent solutions was prepared in separate stainless steel trays using deionized water. The solutions were heated to and maintained at 140°F/60°C.

 

III. The Experiment

  1. A gray lens was examined under a high-intensity light source and any cracks or scratches were noted.
  2. 500mL of 4% VALTRON DP048 was prepared in a stainless steel tray. The solution was heated to and maintained at 140°F/60°C.
  3. A gray lens was placed in the detergent solution and soaked for 10 minutes.
  4. The lens was removed from the solution and was given a 15-second spray rinse of low-pressure deionized water at room temperature.
  5. Next, the lens was given a final wipe with PM solvent.
  6. The substrate was allowed to dry and then examined under a high-intensity light source for any microcrazing.
  7. Steps 1-6 were repeated with the gray and brown lenses using 4% VALTRON DP048, 4% VALTRON SW4110 and 4%VALTRON DP95013.
  8. The results are summarized in Table 1.

 

IV. Results

Lens VALTRON Detergent Conc.
(Vol. %)
Soak Time (Min.) Temp. (°F/°C) Results*
Gray DP048 4 10 140/60 No microcrazing observed. Solution was cloudy
Brown DP048 4 10 140/60 No microcrazing observed. Solution was cloudy
Gray SW4110 4 10 140/60 No microcrazing observed. Solution was cloudy
Brown SW4110 4 10 140/60 No microcrazing observed. Solution was cloudy
Gray DP95013 4 10 140/60 No microcrazing observed
Brown DP95013 4 10 140/60 No microcrazing observed

*Small cracks and scratches were visible on the lenses and were noted before testing.

 

V. Conclusion

The low-foaming neutral VALTRON detergents evaluated in this experiment are compatible with the polarized polycarbonate lenses. No microcrazing or damage to the lenses was observed following the completion of the experiment.
