UV absorbance testing on waxes and sealants

this is an easy test i dont see why people are making it so extreme, its like testing sunblock in a tanning bed, it will work and the rays go through the clear plastic. I give up on this thread haha

Oh come on now---you were doing so good. :)

Before you 'give up' on this thread: Would you be willing to do the UV absorbance testing for this forum's members, posting your results? It could relieve some folks anxiety. Thanks in advance.

Note:

I personally think testing for waxes and sealants "reflectivity values" would better represent their validity for UV protection!
 
haha if this really is a concern to people maybe after sealant/wax, they top it off with some spf 30, i personally am not concerned, just was giving a suggestion on testing

LOL. IMO...Besides the 'built-in' UV protection the clear-coat paint itself has, applying a sealant/coating that has the shiniest, glossiest, most mirror-like finish would be an enhancement for the paint in this battle against UV rays.

BTW, I know of people who actually apply 303 Aerospace Protectant (SPFi 40?) as a "topper" to their LSPs...oh well. :)

Nice talking with ya. You and yours have a wonderful 'rest of the day'.

The great thing about using a setup similar to an eye-glass UV tester/analyzer is that whether the UV was being blocked by absorbance or reflectivity, the results would be exactly the same to the machine (it's only concerned with the % in versus % out of the lens).

Really? I will have to search for that. Any pictures or info available? That would be a great product to throw into the test pool for curiosity.

For consideration purposes only:

How about contacting IU's research depts. and see if the've run any Xenon Arc Light Exposure Testing under the auspices of ASTM D 4587, ASTM G 155, or similar ISO/OEM appropiate and approved standards. Therein could lie some of the answers you are seeking.

Very good idea. I don't know anybody involved in the use of that type of equipment, but you gave me another idea; don't we have an optometry school here?

IU has an excellent School of Optometry...maybe this could also be another source for your attempts at garnering your intended information.
 
i am worried you guys have lost control and will be testing sunglasses with sun tan lotion in a room where the walls are paded

LOL. Some of our quests do become errant in nature.

I caught my "better half" checking out this site..New Page 1...she said it was because of my condition :buffing:

Haha. Thanks for the encouragement. We're all on our way there in some way; I was just hoping I could find some support from enablers on this crazy forum for people overly concerned with shiny objects like myself. Perhaps we need a forum for people trying to drop the addiction?
 
I think she must mean she thinks the UV inhibitors in the clear coat.
 
Did some googling for books/articles:

Pages 643-646 discuss ultraviolet radiation as it relates to paint weathering
Paint and coating testing manual ... - Google Books


I found this post on the detailing world forum which I am not currently a member of:

Accelerated weathering testing for waxes
Hello,

I would like to make a proposal to you out there who are interested in the durabilty of wax.

Currently I work in a polyester reseach and development lab in the polyester chemisry industry.

I have a massive interest in detailing and love to keep my car looking good.
So enough of the boring bit...

To my full use a QUV acclerated weathering testing machine which replicates weathering to which specifcations the customer wants. Ours that we have at work are set to weather in florida as this is classed as a one of the best or worst for degredation of fiberglass in weathering terms and gloss.
This machine works in terms of uv bulbs/humidity and also temperature.

Proposal of testing some wax/sealents to see their durability. I would like to test this on fiberglass as its what i work with and have an abudance of. I can test panels in colour with photospectrometer to see how they/if protect against UV degredation. We also have a gloss meter.

I would like some thoughts so i can write up a test plan and get started.

Also i would like to ask for some help if i am to get this started if some of you can help with very very small amounts of wax enough to cover 20cm square no more than a figernail in some clingfilm say???

Many Thanks

I could not turn up any news of any actual tests being carried out. I will contact the poster (burger) and try to find out.
