Acrylic paint sealant??

So acrylic and polymer are the two big hitters in the sealant game (thats what ive read the most about anyway)...what would be the difference between the two..and what classifies if one is polymer or acrylic?

Acrylic as used in automotive use is usually a term meaning that it contains polyacrylates. They contain a vinyl group in the actual molecular sense. They are known for a high elasticity and resistance to breakage (shattering and cracking). Acrylic polymers are also heat and oil resistant.

Polymer sealants can refer to any coating that is applied and cross links to across the surface of the paint. For instance the MSDS sheet for many polymer sealants shows the use of polydimethylsiloxane PDMS. This group when cross linked is extremely hydrophobic and causes great beading. PDMS will also flow over the surface of the paint and become level, then cross-link to form an elastic coating.

For a sealant to last a year would mean that degradation due to heat, UV radiation and various interactions with contaminates and air is very slow. To last 3 years would mean that the sealant is nearly inert to everything. However, things like rain, snow, bird crap, sprinklers, and dust can all bring a different variable to help degrade a polymer. If UV radiation from sunny days doesn't degrade it, then the acidity of bird crap surely will. If those two don't work, a sprinkler with hydrogen sulfide dissolved in the water combined with road contamination in the form of salt spray will break down the shield eventually. I'd have to call BS on 3 year sealants. The beading may remain but the protection of cross linked monomers surely will not.
 
I was reading an article by Dr. Ghoudussi (I know I spelled it wrong, sorry Dr. G) of Optimum and he was discussing Acrylics. One thing I remember him stating was that Acrylic Sealant stand up to the acids in acid rain (hence waterspots) very well.

Who/what is DuPont?

The only major sponsor that Jeff Gordon has had since he first raced in the Cup series.

His pit crew was originally known as the "Rainbow Warriors", named after the rainbow paintjob on his DuPont sponsored Chevrolet.

Megs 20 is a polymer sealant.

2 examples of acrylic sealants are Klasse AIO, and Blackfire Wet diamond, sealant products.

I don't think bfwd is considered an acrylic sealant. The % of acrylic is almost nonexistent from what I understand.

I have MSDS for BFWD right in front of me, it says <1% acrylic. I'm guessing they used it to add a little thickness to the product. Crystalline polymers in solution are normally pretty thin and since the emulsion contains a light petroleum distillate, probably similar to mineral oil, the acrylic level being that small doesn't stand out as an active ingredient.

That's exactly what I thought the case was Jon. I have read that and think you nailed it. Thanks for clearing it up for us.
 
This is waaaay off topic but... OCDetails... in your sig line you have your business name misspelled. Obessive instead of Obsessive. :)

I cant put the link but if you go to proper auto care you can read the history of the product and the new reformulation which was done a few years ago.

From what is stated by the manufacturer BFWD is an acrylic sealant.
 
I have a few experiments with polymer and acrylic going on. My 5ver RV has half with ZAIO and ZCS the other half has the Klasse twins and one 2@10 foot section has 303 buffed in with a rotary and wool pad. The 303 has been there for 2 months and holding up very well. I also did the same with the hood on the wifes Toyota Sienna hood, Half with ZAIO and ZCS and the other half with Klasse. This Arizona sun is a killer for Carnuba so I will see how all of this holds up.

Thanks, this is where I was quoting my info from.
Here's a partial quote from the highest level on the forum of the same location you mention. "On the MSDS sheet for BF Wet Diamond, it states there is an acrylic in it. The acrylic we use is a thickener and constitutes less than 1%, (which technically we do not have to mention on the MSDS because the amount is so small).
 
Klasse and Werkstatt are the two most common acrylic based sealants, cannot remember if LiquidGlass and FinishFirst was also ??

Yep, Klasse and Werkstatt are the only two that I am aware of, not sure about the other two you mention.

Anyone else know of other Acrylic paint sealants?
 
What about Sonus Acrylic Glanz, Chemical Guys Factory Seal, and Chemical Guys Blitz?

good info, thank you.
 
At the GMC dealership I worked at going through school sold a "Simoniz" protection package for the exterior and interior upholstery for $500 Gauranteed protection for 5 years. Not sure if it was acrylic or not but it didn't work. I had a hood from a 2000 Bonneville that I borrowed from the parts department that I would test the durability the different waxes we had there and to make a long story short the Simoniz only lasted a could weeks of just sitting outside on the weather. It didn't hold up to Degreaser at all. We had a carnauba based wax called royal blue thT actually outlasted it that only cost $15 from our supplier. It was definatley not worth the money.

Just a side note. NEVER purchase these "couch potatoe" protection packages. Two BIG reasons.

1. The guy applying it most likely does not know how to apply it correctly and does not care because he is a young punk working for $8 an hour and uses the same bucket to wash wheel wells and paint repeatedly without renewing the shampoo. I worked with THIS guy and eventually told him not to touch the cars when the packages were purchased because come on, these people are already being ripped off for some serious coin and the least that could be done is a proper application.

2. Every single car on a car lot is swirled! I don't care if it has 5 miles on it; its swirled. You can thank the guy mentioned above for that!
Since the paint is swirled and a paint correction is not included in the $500, you will be applying a $500 sealant over top of the swirls and locking them in for "5" years. The only way to remove the swirls is to REMOVE all of the precious sealant that you paid a crap ton of money to be put on.

It's sad but you would be surprised how many people actually pay to have this done. It's too easy when it was thrown in with the loan....
