Silica Content

[kevincwelch]

As my experience with silica coatings grow (and I have access only to prosumer versions of them), I am still on my quest to find the perfect coating for me. I've tried CarPro, Gtechniq, PBL, WG, Gyeon, 22PLE, Polish Angel, spray coatings and TACSystem now. As of late, my favorite has been Gyeon Mohs. I wanted to get some insight from people who know as to what the silica content is for the various paint coatings. This information is fairly hard to find on the websites. So, if you have any information on the coatings, I'd like to generate a list for myself (and others). I know silica content in spray coatings like Wet Coat and Gyeon Bathe+ is <5%, so that's pretty low. There is published information regarding the silica content of some coatings that aren't sold here, so I won't duplicate those. But for the ones that are sold here, I'd be interested in knowing if others have this information.

I've used moonlight and documentation states 20-25%....i've also heard the Gyeon can coat is about 5%

CarPro's CQUK offers the highest content of Si02 of any of it's consumer coatings. CQUK is formulated with 70% SiO2 at 99% purity. While CQuartz TiO2 offers much less Si02 than UK, it has other proprietary ingredients that make up its own strengths.

I guess you are talking about in the cured coating? Because in the uncured the percentage would be a bit of a red herring.

Isn't Cquartz classic a mix of TiO2 and SiO2?

I'm just curious about the uncured content. I would think it'd be hard to assess the matrix once cured - other than by thickness and hardness.

Bolded word is most important here.

CQ classic has morphed into CQ Ti02 and is now refered to as such. And yes you are correct it contains both Tio2 and Sio2.

I guess I'm just thinking about what is volatile and what is reactant...couldn't you theoretically have a 1% Si content that winds up being 100% when it's cured, vs a 5% that has other "resins" and when it's cured and winds up being only 10% when it's cured? Maybe I'm not thinking about this the right way.
