Dish Test
« on: January 25, 2012, 02:57:24 PM »
Do you guys subscribe to the contention that encap cleaners should dry to a brittle shell?

I did a dish test on two cleaners. I placed 1 mil. of solution of each cleaner in a dish at full strength and let it sit for about 3 and  a half hours.

The one on the left dried to a sticky, gummy film, maybe it wasn't completely dry. The one on the left was dry and brittle and scraped off easier.

I subscribe to drying down anything I use for cleaning..........using the diluted formula that would be used to clean NOT concentrate.

It at least gives you some idea of what could be happening on the carpet.

Ditto with Mike, the test need to be with recommended dilution rates. Some encaps you find will shatter others will become a film. Both have good arguments supporting the differences. I use both and find no longer time spans between cleanings to vary much.

I do both ways
full strength and diluted to action cleaning ration  :ph34r:

agree with what Mike said

when i was making the transition into VLM I bought all encaps I could.
SO glad i did because at the time I was using prochem - procaps  :knuppel2:
never fully dried, and stayed sticky - can you say rebadged shampoo? :crazy2:

I tested one product recently both out of the bottle and mixed RTU.  The undiluted one never dried and remained sticky/gooey just as it came out of the bottle even days later.  The one that was mixed with water crystallized, expanded, and shattered just great.  I guess with a few of them the chemistry changes when you add water.  Some of the lower quality ones probably have a lot of water added to them already.

These might help with this topic:

http://bonnetpro.com/encapsulation/T2H_polymer.html   This uses an electron microscope and is more reality than the dish test.

http://bonnetpro.com/encapsulation/Hoax_7.8.html  This article has been updated

Did you know that the coating on a carpet fiber of encap polymer is under 1 micron thick? To put this into perspective, a pin head is 2 millimeters. A drop of water on a microscope slide is approximately one millimeter. A micron is 1,000 times smaller than 1 millimeter. We're talking about a coating on the surface of a filament of carpet fiber that measures about 50 microns (40xs smaller than a pinhead) or a third the diameter of a human hair. So to pour the chemical full strength into a glass or on a plate for the currently accepted dry down test is 1,000 to 10,000 times thicker than the use of a product in the real world

Both of these pics are the same carpet.

Nice. That clears things up.
