Biocide free pure silicone finish
Performance enhanced - emissions reduced

The ultimate fouling
release coating
PPG Protective and Marine
Coatings is dedicated to the
development, manufacture and
supply of coatings to meet the
very challenging needs of specific
industries. With a heritage of
outstanding expertise in coatings
Building on the success of SigmaGlide 890 and with a track
record of 200 full scale applications, PPG Protective & Marine
Coatings develops the pure silicone technology even further and
introduces SigmaGlide TM 990.
SigmaGlide 990 is the biocide free fouling release coating of
the future.
This highly engineered pure silicone finish brings unrivalled
advantages to shipyards and operators worldwide.
Together with SigmaGlide 790 tiecoat, this revolutionary two
pack fouling release system offers highly enhanced technical
features in comparison to competitors’ products and is the most
effective solution against fouling on the market today.
Due to an increased solids content, both the VOC emissions and
the environmental impact are reduced.
SigmaGlide 990 has widely been embraced by shipyards
worldwide thanks to its enhanced technical features. Its wide
application window and improved curing, make it easy to apply
in demanding weather conditions. The increased sag resistance
of 100%, from 250µ WFT to 500µ WFT, drastically improves the
application in the critical overlap areas.

The ambition of PPG Protective and Marine Coatings’ R&D department
is to develop state of the art products which support
customers operations. Being both responsive and robust requires a
fundamental understanding of chemistry and physics as well as the
market needs.
Test patch
Using surface analysis, contact angle measurements and electron
microscopes to assess and understand the mechanisms, the R&D
Department also partners up with customers and suppliers.
To assess performance, raft testing at various locations around
the world is one of the core activities in combination with trial
applications on commercial vessels.
All activities are part of our continuous efforts to improve the
performance and application features of the Sigma Coatings
products and ensure their market leading quality.

With the new Sigma
We protect the
environment
The SigmaGlide range, including SigmaGlide 990, is completely biocide free and is
therefore unaffected by such legislation as the BPD – Biocidal Products Directive.
It meets all current environmental legislations and is tailored to comply with future
environmental restrictions in order to accommodate all ship operators’ compliance
programs. With a very high solids content ( 80% ), SigmaGlide 990 easily meets the
SED – Solvent Emissions Directive. Even after extended service life only one refresher
coat is needed for a new 5 year sailing period.

We help operators to
increase their revenues
Careful screening of fouling release technologies is of vital
importance in the modern shipping industry. Reduced hull roughness
provided by a smooth, fouling free coating will lead to immediate
improved performance and lower fuel consumption.
SigmaGlide 990’s new formulation keeps the hull free from macro
fouling, drastically reduces the slime growth even in the critical
boottop area and helps to decrease the Average Hull Roughness.
At outdockings, vessels coated with SigmaGlide 990 have
recorded values down to 70µ AHR.
The reduced indocking period for hull cleaning / coating, the
decreased volume and weight of paint required and the reduced
wastage from this high solids two pack system, result in significantly
lower application costs, which will benefit the smart operators
choosing SigmaGlide 990.
