Advantages of using SantoLight SL-5267:
1.67 refractive index: Allows index matching to high high index plastics, glasses, semiconductors
Low viscosity fluid: Allows rapid dispensing to large assemblies
Chemically inert: Non-toxic, compatible with optical grade materials
Optically clear: Efficient optical transmission for wavelengths > 430 nm
High surface tension: Non-migrating as a thin film
Low volatility: Eliminates recondensation contamination, ensures long service life
High purity composition: Low ionics ensure no degradation of sensitive semiconductors, metals
Wide temperature service: Suitable for outdoor environments

De-aereation (removal of air bubbles):
If air bubbles become entrapped in the dispenses fluid volume during the dispensing process, the assembly should self-de-aereate as long as no pockets of air are trapped beneath mechanical parts. If accelerated de-aereation is required, the assembly may be vacuum de-aereated using a roughing pump vacuum pressure of 500 mm Hg or greater. Apply the vacuum while observing the fluid for presence of bubble formation and increase vacuum slowly enough to avoid rapid foaming. Hold vacuum until air bubbles are no longer visible.

Optical material compatibility:
SantoLight SL-5267 is inert and compatible with most optical glasses and semiconductors. Substrates to avoid include: ester-vulnerable plastics such as poly styrene and ABS. Some seal materials such as butyl rubber will show swelling when in contact with SL-5267 for extended periods at temperatures in excess of 100°C.

Substrate preparation:
Substrates should be free of dust, oil and fingerprint soils. Clean substrates using suitable industrial techniques for cleaning electro-optics. If hydrocarbon solvent cleaning (e.g. acetone) is used, a final rinse with reagent grade isopropanol is recommended. If aqueous detergent cleaning is used, multiple final rinses with di-ionized water or a single rinse with reagent grade isopropanol is recommended. Always use suitable lint-free wipers with cleaning sensitive optical substrates, lenses, cover glasses, and other optical materials.

Clean-up:
SantoLight SL-5267 may be removed from surfaces by first wiping off excess fluid with a suitable paper or cloth wipe and then using Alconox^® or Liqui-Nox^® or alternatively, with a suitable lint-free cloth soaked in acetone. If acetone residues are undesirable, the clean-up process should be completed with a final rinse with reagent grade isopropanol. The user is responsible for compliance with all applicable local, state, and federal regulations governing disposal of waste materials as indicated in the MSDS.

Specifications:
The typical properties quoted should not be used as a basis for preparation of product specifications.

Shelf life:
SantoLight SL-5267 is an inert fluid with no intrinsic shelf life limitations. It will, however, suffer changes in properties if removed from its original container and subjected to environmental conditions, as indicated in the typical properties list.

Warranty:
SantoLight SL-5267 is sold without warranty, express or implied. SantoLight expressly disclaims any liability for incidental or consequential damages resulting from the use of this product. The user is advised to conduct thorough design, qualification, and testing studies prior to approval of SL-5267 for any production process or product component.

Safety:
Consult the MSDS for SL-5267 before use. SL-5267 is an industrial product, designed for use only by qualified laboratory or production personnel.
