Dow launches low odor binder for HP paint
Dow Coating Materials has introduced a new binder technology
designed to help formulators develop
low-odor paints with outstanding
performance. Dow is integrating this
technology with other initiatives to
achieve extremely low odor profiles
in high performance paints. The first
example is Rhoplex VSR 2015 with
Versair technology, which was introduced earlier this year. By incorporating Versair technology into
Rhoplex VSR 2015 chemistry, Dow is
able to achieve these low-odor characteristics without compromising the
paint performance and low- to no-VOC formulating capabilities inherent in Rhoplex VSR 2015, according
to the company.
The Versair technology platform
addresses the issue of paint odor from
a holistic perspective – looking at not
just every material in a can of paint,
but how those materials interact during formulation and application as well.
PERSTORP OFFERS
CHARMOR POLYOLS FOR
INTUMESCENT COATINGS
Perstorp recently launched Char-
mor polyols for use in intumescent
coatings. Micronized and supermi-
cronized Charmor polyols create an
advanced char barrier for steel and
wooden structures. When exposed
to fire, intumescent coatings with
Charmor swell 10 to 100 times
their original thickness to form an
insulating carbon char barrier that
protects the substrate and building
structure for a longer period of
time than any other comparable
product, according to the company.
Perstorp’s high purity micronized
polyol products improve fire protec-
tion by increasing the insulation
effect of intumescent coatings. The
carbon in Charmor forms a thick
fire-resistant char barrier that
helps to prevent the substrate from
catching fire or distorting when a
coating is exposed to temperatures
over 250°C. The intumescent process
starts at 250°C. Steel loses its
strength at about 550°C.
ISP LAUNCHES JAYPOL
PERFORMANCE ADDITIVES
International Specialty Products (ISP)
has introduced Jaypol performance
additives, functional products based on
acrylates chemistry. A series of Jaypol
dispersants, co-binders and rheology
modifiers made available by ISP offer
manufacturers new options to produce
water-based coatings of superior quality
with excellent efficiency and economics,
according to the company. Most Jaypol
additives are engineered to advance the
processing and performance attributes
of coatings at low use levels. ISP offers
the new Jaypol series of performance
additives in sodium and ammonium
formulations for manufacturers that
require flexibility in tailoring the moisture resistance attributes of dry film,
the water sensitivity of produced coatings, and other requirements, such as
electrolyte tolerance.
OXEA LAUNCHES OXFILM 351
COALESCEING AGENT
Oxea has launched Oxfilm 351, a
next generation coalescing agent
that is virtually odorless and non-
VOC. With a boiling point of 351°C
(664°F), it has negligible contribu-
tion to a coating’s VOC content. In
addition, Oxfilm 351 is 10-20% more
efficient in reducing the minimum
film forming temperature (MFFT)
than other coalescing agents, accord-
ing to the company. Oxfilm 351 has
been shown to be an efficient coalesc-
ing agent for a broad range of latex
and coating types.
COGNIS OFFERS DISPONIL NG,
NON-IONIC SURFACTANTS
Cognis has launched Disponil NG
series of APEO-free, VOC-free and
FDA-approved surfactants. In accor-
dance with Cognis’ Greenovating
strategy, the Disponil NG series
seeks to bring sustainability and per-
formance together: based on renew-
able raw materials, the Disponil NG
series offers several benefits in the
emulsion polymerization process as
well as in end users’ applications,
such as being gel-free, showing fast
foam decay and having low pour
points. The Disponil NG series of
surfactants are based on modified
natural and renewable-based fatty
alcohols combining performance,
handling and environmental sound-
ness, according to the company. The
Disponil NG series comprises surfac-
tants that are suitable for all types of
latices as in-process non-ionic or as
post-stabilization surfactants. They
show excellent phase behavior,
meaning that when diluted with
water, there are no gel phases over
the entire concentration range.
Additionally, they ensure rapid foam
collapse in the surfactant solution as
well as the finished latex, and they
have low pour points even lower than
- 15°C. These properties result in eas-
ier handling and reduced energy con-
sumption during latex production
compared to traditional surfactants.
Emulsion production times are
reduced, and the manufacturing
process can continue even at very
low temperatures. CW
