NP9 Surfactant & Caustic

Does anyone have an idea on a good amount of NP9 to put into 55 gallons of DS'able caustic degreaser? I tried 1 gallon but it fell out of suspension so I am unsure on a good number to start with. I plan on acquiring a mixer to mix the chemicals thoroughly. :bash:
 
You've got to get the mix order right. Caustic must be mixed last in most any formula. Get the surfactant and any other ingredients in solution first, then add the caustic.

My caustic degreaser actually has 6 different ingredients including about 1 1/2 gallons of N9.5.
 
Thanks Russ, this is something I have never herd of being talked about. For the most part chemicals are not something spoken of especially the process of making them. Whats the difference in np9 and 9.5

Thanks again for the input

That's because manufacturers are pretty tight lipped with their secrets. That's about all you'll get out of me, too. I won't divulge formulas, but a tip like that won't make or break me.

There's very little difference between 9 and 9.5. What you're using is fine.

And, if you're needing raw materials, let me know. I buy them in bulk and can sell 5 gallon quantities.
 
NP 9, NP 9.5, 9.5 Mole, Vanwet 9N9, etc. are all non-ionic surfactants and are basically an all purpose detergent and wetting agent. These surfactants are stable in the presence of acids, bases, and salts. They are also miscible with chlorinated and aromatic solvents and can be coupled with Butyl solvents and other aliphatic and aromatic solvents. Surfactants usually will not "fall out" of a solution. So in layman's terms....... Any of these surfactants will work well in our industry. They will mix well with any application. If you think think your surfactant may have fallen out, you simply may have not added enough to your solution. Hope this helps.
 
In my mixing days I put the caustic in first to generate some heat then the surfactants. It helps them to dissolve more thoroughly.
 
Yes, caustic will generate heat when mixed with water. NEVER NEVER add water to caustic or acids. You must always add caustic or acids to water. While most people add caustic last, including me, it will not do any harm at all if you mix it first. It will help mixing especially if you are adding TSP, Sttp, or any other dry chemical. Just remember to wear proper safety equipment while mixing. Caustic can cause serious burns and can blind you if you do not wear proper PPE.
 
Your tellin me .. I love caustic.. Especially when you get a cut or something... you just put a little on a cut a whala it stops bleeding ..LOL.. the real fun is when you get to a restaurant with really hot water and mix the caustic.. I have always put caustic beads in the pump up sprayer first , then a squeeze of dawn and then hot water.. But thats just me .. Crazy I guess...
