I've never used any chemical from KR, but I do use JBS and if it is a relable of their chemical, I would say that it is pretty good. I've been using JBS for several years and have been very satisfied, they're very good people to deal with.
What I've been told is that JBS use to make it and sold the recipe...I don't know who makes it now. Perhaps when I get the MSDS sheet it will shed some light.
Apparently this is their best seller...so some of you have to be using it and I'm just asking for your non-scientific impressions.
Is that the purple stuff? I used to use kr chemicals and was satisfied with everything but the presoak. It is not nearly as concentrated as their other chems.
Sodium Hydroxide and Potassium Hydroxide are essentially the same chemical ingredient - caustic soda. They are often used interchangeably to increase alkalinity.
