Below are representative lists of chemicals and materials to be used or avoided in LeD manufacturing activities. For a complete and
current list of recommended chemicals, conformal coatings and harmful chemicals consult Cree’s
Chemical Compatibility Application
. The video at

illustrates the process Cree has developed for testing the compatibility of
chemicals and materials with LeDs. You should also consult your regional Cree Field Applications engineer.

Chemicals Tested as Harmful
In general, subject to the specifics in Cree’s
Chemical Compatibility Application Note
, Cree has found certain chemicals to be harmful to
XLamp MT Family and MK Family LeDs. Cree recommends not using these chemicals anywhere in an LeD system containing XLamp MT
Family and MK Family LeDs. The fumes from even small amounts of the chemicals may damage the LeDs.
•
Chemicals that might outgas aromatic hydrocarbons (e.g., toluene, benzene, xylene)
•
Methyl acetate or ethyl acetate (i.e., nail polish remover)
•
Cyanoacrylates (i.e., “Superglue”)
•
Glycol ethers (including Radio Shack

Precision electronics Cleaner - dipropylene glycol monomethyl ether)
•
Formaldehyde or butadiene (including Ashland
®
PLIOBOND

adhesive)
Hermetically sealing Luminaires
For proper LeD operation and to avoid potential lumen depreciation and/or color shift, LeDs of all types must operate in an environment
that contains oxygen. Simply allowing the LEDs to ventilate to air is sufficient; no extraordinary measures are required. Hermetically
sealing LeDs in an enclosed space is not recommended.
