International Paint offers a choice of
silyl and copper acrylate technologies
International Paint has introduced Intersmooth 7465Si SPC and Interswift 6900Si
silyl acrylate antifouling coatings.
Aiming to improve and enhance customer choice, International says it is the
first and only global manufacturer to offer
both copper acrylate and silyl acrylate antifouling coatings within a comprehensive
range of fouling control technologies.
In 2006, International Paint patented
silyl acrylate technology for use with
products of less than 400g/l VOC. This
technology is incorporated into Intersmooth 7465Si SPC and Interswift 6900Si
and allows delivery of the same high levels of proven in-service performance as the
current Intersmooth 7460/5HS SPC and
Interswift 6800HS copper acrylate antifouling coatings.
Both new silyl products have solvent
emission levels of less than 400g/l VOC.
Designed for deep sea vessels at newbuilding and maintenance and repair, Intersmooth 7465Si SPC features 55
percent volume solids. Compared to
lower volume solids products, this results in shipyard benefits of faster application, reduced wastage and pail
consumption and lower solvent emissions to the atmosphere. Reduced overspray leads to lower contamination
levels in dock and reduced applicator exposure. For the vessel operator, the product delivers predictable, high
performance fouling control for up to 90
months and its inherent self-smoothing
action potentially reduces fuel use by
four percent, cutting operational costs,
lowering carbon dioxide emissions and
improving vessel operating image said
the company.
Interswift 6900Si incorporates
patented silyl acrylate polymer technology.
Also designed for vessels at newbuilding
and maintenance and repair, the product
offers 61 percent volume solids, surface
tolerance and in-service periods of up to
60 months with potential fuel savings of
1.5 percent said the company.
Oxford Advanced Surfaces
unveils its new technology
Oxford Advanced Surfaces Group Plc
(OAS) has produced a solvent resistant
oleophobic and hydrophobic coating system using its proprietary technology—Onto
XL Highly Reactive Chemistry. The technology has been used to modify the wetting
and surface energy characteristics of both
glass and plastic substrates, but could also
be utilized on other materials. A common
approach for simultaneously imparting
both hydrophobic and oleophobic functionality to a surface is to coat it directly
with a fluoropolymer but there are often associated problems with the stability of the
film towards solvents, especially on plastic
substrates. Using Onto XL technology in
conjunction with a fluoropolymer prevents
delamination to result in an oleophobic/hy-drophobic surface that is stable to solvent
exposure said the company.
The coating is applied in two layers
from non-fluorinated solvents by common
wet chemical processing techniques, giv-
ing it scope to be printed and therefore
patterned. “This technology has the po-
tential to be used in several applications
but we believe that one of the most im-
portant markets will be organic electron-
ics,” said Sarah Vickers, product
marketing scientist at OAS. “The use of
Onto XL to anchor a coating to a sub-
strate is not confined to fluoropolymers
and has the potential to be used in con-
junction with other types of coating.”
OAS is an innovative research and devel-
opment company delivering highly ad-
vanced materials solutions in optical
coatings and highly reactive chemistry. Its
proprietary technologies, Onto highly reac-
tive chemistry and VISARC anti-reflective
coatings, deliver performance-enhancing
processes, opening up new markets for the
most desirable high-performance advanced
materials said the company. Initial applica-
tions include adhesion promotion, surface
treatment and anti-reflective coatings used
in the large volume, high-growth markets of
