Something that caught my attention after buying the kit is DAG 156 has a shelf life of no more than 2 years. Worse, if you were to buy from Ladd Research, which also happens to be the only place I could find the TDS for DAG 156, you are only guaranteed a 90 day shelf life on lubricants and fwiw, paints. Since Boeing also distributes the same product and they list 720 days, they certainly want you to believe the shelf life is a real thing.
I suspect DAG 156 shelf life is more about needing to thin with isopropanol than anything, but if that was the case they should say that. Instead I can only choose between deciding, is it junk after not much time after I purchased it, possibly even before I purchased it, or are they just greedy and don’t want to say the product can be thinned with isopropanol? Truth be told, I have been experimenting with DAG 156 for several months now and have noticed no signs of needing to thin the product and no change in performance.
After all is said and done, the better option may be from Huron Industries. Their colloidal graphite comes in two different, albeit similar offerings. NEOLUBE No.1, and No.2. Both are designed to be an anti-seize and lubricant for use at nuclear facilities, as is DAG 156.
No.1 has the same mil-spec (MIL-L-24131C) in the TDS as DAG 156. However, Huron is fine with thinning the product if needed and lists an indefinite shelf life for unopened containers (both variants). It seems like Huron has more confidence in their product than Henkel.
As for NEOLUBE No.1 No.2, if you are going to use colloidal graphite as anti-seize for rifles, No.1 is obviously better for higher temps but questionable if in fact the higher grade is needed. I have yet to get a reading close to 400°F on any of my bolt rifles and would be very concerned if I did. As for a semi-auto, while I have never bothered to check the readings, all those mil-spec rifles that use permanent thread sealant are banking on them staying under 400°F. Or at least they should be since that is what you heat it to to break the thread sealant loose.
For myself, I did order up a bottle of NEOLUBE No.1 and am just waiting on the delivery. Since MIL-L-24131C requires testing for graphite content at 570°F for approximately 1.5 hours, it stands to reason that No.1 does a better job at handling operating temp cycles over time and I want to find out if there is a noticeable difference between it and DAG.
I am willing to say having the mil-spec version just adds to the comfort level and No.2 would be sufficient. After all, while I am sure the total of my barrels and actions don’t even come close the cost of a nuclear reactor (Yes, relax, I am aware nuclear facility does not equate to reactor). But it sure hurts like heck every time I buy one so I spent the extra $10 for the certified product.
If NEOLUBE will turn out to be any better than DAG, maybe time will tell because I unless there is a noticeable difference in the application itself, I have a feeling I won’t be able to say one way or the other.
