Bought some NAPA Sil-Glyde and just happened to google it's patent number.
It is going off-patent. This stuff approx 60+ yrs old since its patent filing.

Sil-Glyde Patent Link

Update: It has some UV blockers. Applicable: sun screen for the summer time. LOL

I read the NEW GOLD standard is Mission Automotive silicon paste for caliper pins.

Mission Automotive Paste



Looks interesting, good temp range. Has a lot of good reviews. I did notice that on the back label it says Kosher approved? Didn't know that was a thing for grease!

In light of the recent Wash DC turmoil, I hope in the near future there is more inclusion and include a future halal approval.

Oh my, I believe you have established yourself as the Sil-Glyde OCD guru of BITOG. Your patent pdf link is awesome.

I have always had a fascination with Sil-Glyde and have talked with the guys at AGS in Muskegon once or twice. The Critic,myself, and others have corrected people numerous times about it not being a true silicone grease (The Critic has moved on to more skilled topics). But, that does not detract from it being a superb brake lubricant as proven by the many testimonials from both newbies and old timers.

Thanks for posting that fascinating patent article. I wonder if anyone will duplicate it after it goes off patent?

Thanks for the compliment. To be honest, I just bought my 1st tube of NAPA Sil-Glyde and was just reading the label when I stumbled on the patent # for google look-up. Unfortunately, I also bought the Mission Automotive silicone paste and have decided to use it for my brake calipers' pin this summer. Lower and upper temperature range.


The patent abstract was definitely an interesting read and provided 1958 insight into solving a lubrication problem by blending existing properties: castor oil, silicone and propylene glycol.
 
Re-read the patent abstract.
In 1958, lubricants with > 50% silicone was prohibitively expensive and the author questioned silicone grease's film lubricant properties. The inventor did an excellent job blending the properties of castor oil and extending the temperature range properties without going to the expensive silicone. He did suggest silicone's higher water-replenency properties. You know what I am thinking.

Hybrid lubrication on the caliper pin.

Top portion of the caliper pin including the boot-Mission Automotive. Seals out water real well. And the remainder of the caliper pin- NAPA Sil-Glyde. Excellent lubricantion properties.

Who wants to try out my idea?

I have 5/32 on my pads and will not get to it until this summer.

Yes, the patent repeatedly mentioned he thought there was synergistic effect of mixing the separate components.

I could not find any data on the Mission Automotive grease. To me, it seems to just be a repackaged product without anything showing it to be equal to or better than other products (besides a lot of internet noise).

Agree. The more I read about castor oil, it's high film strength made it the base go to oil for engine lubrication except for polymerization at high temperature. From the ‘Green New Deal' prespective, castor oil is less toxic than exposure to petroleum hydrocarbon. There is no CA proposition 65 health warnings with Sil-Glyde. The patent inventor is an amazing guy.
 
This is quite a coincidence as I just bought my first tube of Napa Sil-Glyde yesterday.

I kind of wish they sold it in small packets. I don't think i'll ever use the entire 4 oz bottle.

@NAPA $6.69 cheaper than Amazon or buying the AGS from Autozone.

Green new deal perspective? I'm fine with utilizing products that are less toxic, makes perfect sense to me. However the GND has nothing to do with a less toxic product......

Recognizing the duty of the Federal Government to create a Green New
Deal.span>

Which is about trying to achieve NET-ZERO greenhouse gas
emissions

And NET-ZERO is really about establishing a carbon tax and a one world government. Can't have a world government if you don't have a tax base and a power structure can you? You get that with the Paris Agreement and NDC's span> that would be submitted to the UN and distributed to the nations of need.

Nice tidy little setup. Just need to get people to rally behind buzzwords such as Green and Sustainable. It would be one thing if they weren't pining for more power. But that is what this is.



Anyhow side rant that is not particularly germane to the issue of non-toxic substances that can be used to maintain a vehicle. I just found it interesting that you conflate the two subjects. I don't think Sil-Glyde is going to help with global warming

Excellent- thank you! I have some brake work in my future and want to try this.
 
I bought Sil-Glyde several years and it's been around on the shelf or my tool box for years. So it's been used anytime I need a dab of grease. A lot more than brakes.

I just bought my second tube as the first one is almost empty.
 
Also noticed that the max temp range for my tube is 600 F and the newer version is 425 F per the MSDS on Napa’s site.
