Borates

[MolaKule]

ZDDP and MoDTC are generally activated by the higher temperatures found in lubricants, or by the higher pressures found in high load contact areas, which can raise temps to the activation temperature. Muli-functional Borate compounds are excellent cold-temp anti-wear agents, and can serve two other functions. What other functions can a borate compound serve in lubricants? Guidelines for the Question of the Day: 1. No Piston Cup Lapel Pin will be awarded to the same person within 14 days of a previous award. 2. Please respond with a complete sentence. 3. Please do not post links. If a question arises as to the need for clarification, then sources and links may be requested. 4. Please, no off topic posts. Functional names for additives are listed here: Antifoamant or foam inhibitor Antioxidant or oxidation inhibitor Anti-Wear Extreme Pressure Additive Demulsifier Detergent Dispersant Emulsifier Friction Modifier Metal Deactivator Oxidation Inhibitor Rust Inhibitor Pour Point Depressant Seal Conditioner Surfactants Soot Control or Soot Inhibitor Tackifiers

I gotta take a stab at this one. 1. Borates may be found in passivation agents used to inhibit susceptibility to corrosion in ferrous materials. 2. Borates are used in buffer compounds to maintain a desired range of acidity/alkalinity, which also may mitigate corrosion rates. 3. Borate compounds may also be present in detergents.

They also make those little Pyrex containers you use. aka borosilicate

Hint. The question posed is:

I.E., we know it's multi-functional, so what other functional names, from the list provided, would apply?

Thanks Mola for taking the time to start these threads. This keeps the forum interesting!!

I think borates help tbn retention and either act as a friction modifier or anti-wear. Just guessing.

You're getting closer.

 

[SLATRON]

Borates can also be used as an Antioxident for Rust inhibition & oxidation inhibition to stop corrosion.

Ok. I missed that part. Ok then. Tbn retention and detergent/dispersant. I'm pretty sure about the tbn part because through my communications with liqui-moly I learned that their motor oil saver/mos2 and ceratec all contain boron and they informed me that adding them will increase the time between changes. Which leaves it's second function. And thanks molekule for these little quizzes. I do learn much from them,and you. There are a few guys here who make this site worthwhile coming to because of the knowledge they share and you are one of them. Shannow ,Doug Hillary,dnewton,overkill,garak,trav,Shannow,440magnum,fx4 and of course dermapaint and mystic are why I come to this site.(if I've forgotten anyone I'm sorry,which I'm sure I have)These guys are what makes this site great and I'm glad they are here sharing their experiences. There are more but I'm just drawing a blank. I apologize if I missed ya and I'll be sure to add whomever I've forgotten. So back to boron. Tbn retention and extreme pressure additive? Am I getting closer.

1) Rust and oxidation inhibitor. 2) Detergent. Couldn't edit last post fully.

 

[HardbodyLoyalist]

Borates can also be used as extreme-pressure additives, oxidation inhibitors, and rust inhibitors.

 

[MolaKule]

Depending on the synthesis and subsequent functionalization, borates (boron compounds) can be considered as Anti-Wear Additives, extreme pressure additives (EP), friction modifiers, and oxidation inhibitors, and rust inhibitors, and pH modifiers to control acidity. Oxidation inhibitors, rust inhibitors, and alkilinity agents would fall under the classification of "Surfactants." So the two additional functions would be Friction Modifcation and Surfactant. Except for Warstuds post which almost made me lose my breakfast , we'll bestow multiple Piston Cup Lapel Pin awards this time to Clevy, R80RS, SLATRON, and HardbodyLoyalist.
