Hi, I am Mark Rubio, energy
00:00:10:17 00:00:12:08
business manager at Sherwin-Williams
00:00:12:09 00:00:14:06
Protective and Marine Coatings.
00:00:14:07 00:00:16:18
Today I have with me Mr. Neil Wilds,
00:00:16:19 00:00:18:07
our global subject matter expert in
00:00:18:08 00:00:20:10
CUI and insulation.
00:00:20:11 00:00:21:11
And we're going to discuss the
00:00:21:12 00:00:23:01
technical merits of my case cases
00:00:23:02 00:00:25:00
iron oxide enhancements of
00:00:25:01 00:00:26:15
CUI coatings.
00:00:26:16 00:00:28:14
Neil, what is MIO and why
00:00:28:15 00:00:30:02
does it work so well?
00:00:30:03 00:00:31:08
Hi, Mark.
00:00:31:09 00:00:33:08
MIO or micacious iron oxide
00:00:33:09 00:00:35:11
is a platey form of iron oxide
00:00:35:12 00:00:37:12
which is thermally and chemically
00:00:37:13 00:00:39:13
stable, unlike other common
00:00:39:14 00:00:40:14
area pigments.
00:00:41:08 00:00:42:19
There's been use for many years and
00:00:42:20 00:00:45:04
high heat chemical resistance
00:00:45:05 00:00:47:01
and high delta poxy formulas,
00:00:47:02 00:00:49:06
and it works in the following ways.
00:00:49:07 00:00:51:08
When developing formulas for CUI,
00:00:51:09 00:00:52:20
you need to have a significant level
00:00:52:21 00:00:54:10
of MIO to give you the best
00:00:54:11 00:00:55:12
performance.
00:00:55:13 00:00:56:20
In the case of the new Heat-Flex
00:00:56:21 00:00:58:18
range, we have levels greater
00:00:58:19 00:01:01:13
than 25% within the dry film.
00:01:01:14 00:01:02:18
This gives you a very strong
00:01:02:19 00:01:04:15
reinforcement allowing the Q
00:01:04:16 00:01:07:01
films to resist thermal stresses.
00:01:07:02 00:01:08:17
It also gives an extremely good
00:01:08:18 00:01:10:03
barrier protection as the Lamela
00:01:10:04 00:01:12:02
nature of your flakes line
00:01:12:03 00:01:13:24
up in the film to produce a tortuous
00:01:14:00 00:01:15:17
path of corrosion species.
00:01:16:20 00:01:18:17
MIO actually trying mirrors?
00:01:18:18 00:01:20:02
It reflects UV.
00:01:20:03 00:01:22:02
So we also benefit from good erosion
00:01:22:03 00:01:23:24
resistance, less dry film
00:01:24:00 00:01:25:24
thickness loss and on exposure
00:01:25:25 00:01:28:02
to high UV environments.
00:01:28:03 00:01:29:24
All these properties enable us
00:01:30:00 00:01:31:21
to pass the rigorous testing which
00:01:31:22 00:01:34:03
is required for CUI service.
00:01:34:04 00:01:35:20
It also brings the benefit of very
00:01:35:21 00:01:37:03
good corrosion performance at
00:01:37:04 00:01:38:23
ambient temperature, so equipment
00:01:38:24 00:01:40:07
can withstand the extreme
00:01:40:08 00:01:41:24
atmospheric corrosion environment.
00:01:42:00 00:01:42:19
So that's great Neil.
00:01:42:20 00:01:44:12
So how do we test for see why?
00:01:44:13 00:01:45:25
All in all.
00:01:45:26 00:01:47:17
CUI coatings are tested for all
00:01:47:18 00:01:49:22
sorts of scenarios like high heat
00:01:49:23 00:01:52:19
immersion and atmospheric corrosion.
00:01:52:20 00:01:53:20
As this was such a unique
00:01:53:21 00:01:55:15
technology, we decided to test it
00:01:55:16 00:01:56:16
vigorously.
00:01:57:12 00:02:00:06
CUI simulation in ISO 19277
00:02:00:07 00:02:02:03
showed good performance.
00:02:02:04 00:02:04:06
Cyclically corrosive Test ISO
00:02:04:07 00:02:06:05
12944.96
00:02:06:06 00:02:08:09
Give less than five millimeter creep
00:02:08:10 00:02:10:00
well below the less millimeter
00:02:10:01 00:02:11:04
requirement for nonzync systems.
00:02:12:12 00:02:13:24
Better corrosion resistance and
00:02:14:00 00:02:15:13
traditional epoxy products not
00:02:15:14 00:02:16:13
containing them.
00:02:17:04 00:02:18:18
Oh well, thank you, Neil.
00:02:18:19 00:02:19:15
That's something.
00:02:19:16 00:02:21:18
So my concern oxide
00:02:21:19 00:02:23:14
does offer some significant
00:02:23:15 00:02:24:14
advantages.
00:02:24:15 00:02:25:20
I would like to conclude by
00:02:25:21 00:02:27:18
describing our MRO
00:02:27:19 00:02:29:05
enhanced product line, which
00:02:29:06 00:02:31:05
consists of three products that
00:02:31:06 00:02:32:19
cover the temperature ranges from
00:02:32:20 00:02:34:15
cryogenic all the way to 1200
00:02:34:16 00:02:35:17
degrees Fahrenheit.
00:02:35:18 00:02:38:06
First, we have our Heat-Flex 650.
00:02:38:07 00:02:39:13
This is our next generation.
00:02:39:14 00:02:41:08
Two component epoxy phenolic
00:02:41:09 00:02:43:07
enhanced with mild.
00:02:43:08 00:02:46:06
Second is our Heat-Flex 750
00:02:46:07 00:02:48:07
and new chemistry in our portfolio.
00:02:48:08 00:02:50:14
This is an calculated amide epoxy
00:02:50:15 00:02:52:03
also enhanced with MIO, with
00:02:52:04 00:02:54:13
exceptional erosion, corrosion
00:02:54:14 00:02:55:19
and crack resistance.
00:02:55:20 00:02:57:23
And lastly, we have Heat-Flex 1200
00:02:57:24 00:03:00:01
plus, which is a two component
00:03:00:02 00:03:02:01
inert multi polymeric matrix
00:03:02:02 00:03:03:22
coating with improved corrosion
00:03:03:23 00:03:05:17
protection properties, as well
00:03:05:18 00:03:06:23
as being more resistant to
00:03:06:24 00:03:08:21
mechanical damage for temperatures
00:03:08:22 00:03:10:21
all the way to 1200 degrees
00:03:10:22 00:03:12:03
Fahrenheit.
00:03:12:04 00:03:13:15
We're confident that with these
00:03:13:16 00:03:15:07
three options, Sherwin-Williams
00:03:15:08 00:03:16:22
provides customers with increased
00:03:16:23 00:03:19:09
durability, superior performance
00:03:19:10 00:03:20:22
and longer lasting protection
00:03:20:23 00:03:22:14
against. See why?
00:03:22:15 00:03:23:21
We look forward to hearing from you.
