99.9% pure anhydrous (containing the least water possible) isopropyl alcohol is excellent for tape head cleaning, defluxing, stencil cleaning, other light cleaning, and as a flux thinner. Avoid "bargain" alcohols for critical electronic cleaning. Cheap alcohols contain much more water, which slows drying and can cause oxidation.  Avilable in spray and bulk packaging.
 
Specs: TT-I-735 Rev. A, ASTM D770-11, and GE Aviation D5B57

Features & Benefits

  • 99.9% pure IPA
  • Ideal for electronics cleaning & flux thinning
  • Plastic-safe
  • Non-ozone depleting

FAQ's

Why is there an shelf life for unopened containers but not opened containers?

Let’s start with what happens when some solvents are out-of-date. Solvents containing alcohol are hydroscopic, so absorb moisture from the air. What starts as 0.2% moisture could drift up to an unacceptable purity level, as it is exposed to ambient air. If sealed, this will happen extremely slowly. That depends on the packaging and sealing method, which we have full control of.

Once a container is opened, we no longer have control of it, so it is impossible to give a credible number. If you close it after every use, and have a humidity controlled environment, the same shelf life is probably still applicable. If you leave the container open and you are in the tropics, it will probably pass that unacceptable threshold a lot more quickly.

Whether or not 0.5%, 1%, or 10% moisture contamination is acceptable for your operation depends on what you are doing with it. Some aerospace customers absolutely demand their isopropyl alcohol (IPA) is 99.8% pure, so they manage their inventory very carefully. Other customers dilute 99.8% IPA with DI water to make their own 70% IPA for cleaning stencils. There really necessarily  a real-world expiration date for that level of criticality.

How do you know the safe exposure limit of a degreaser, contact cleaner, or flux remover?
The personal hazard associated with a solvent is often defined using Threshold Limit Value (TLV), which is the recommended average exposure in an 8-hour day, 40 hour work week. The lower the TLV of a particular substance, the less a worker can be exposed to without harmful effects. TLV is stated on the SDS of chemical products, in additional to recommended personal protection equipment (or PPE). The threshold limit value of a solvent is generally set by the American Conference of Governmental Industrial Hygienists (ACGIH). The unit of measure is Parts Per Million (PPM).
Can I use a spigot / dispensing spout on the 55-gallon plastic drum?

Yes, HDPE (plastic) drums are designed to accept commonly available 2” threaded spigots / spouts. Spigots are available at distributors, like at https://www.grainger.com/product/GRAINGER-APPROVED-Drum-Tap-6PFN4.
