EPOXY-SILOXANE COATING TECHNOLOGY
1
This document describes an ambiant-cure epoxy-siloxane coating, exhibiting
excellent corrosion resistance, substrate adhesion, flexibility, weatherability
and superior chemical and impact resistance after curing.
The chemical combination of Epoxy and Siloxane results in polymers with
higher performance characteristics than can be achieved by the physical
combination of all polymers. The chemical combination provides the basis for
the joined polymeric strength, weathering durability, high temperature
properties, and radiation resistance, gloss and color retention and corrosion
protective properties of the polymers, whilst overcoming the brittleness of
inorganic structures.
Possible substrates include: concrete, cementious products, arhitectural
blocks, internal / external pipes, tanks, containers, off-shore oil drilling
platforms, metallic framework, bridges, gas turbine engines, heat
exchangers, interior / exterior of ships and aerospace equipment.

Executive Summary
The cost of corrosion in the U.S. piping industry is more than $8 billion
annually. To eliminate this problem, approximately 10% of all new U.S.
steel pipes are treated to resist corrosion. For the same reason,
expensive corrosion-resistant stainless steel pipes and pipe lining are
also being used.
Oil and gas well pipes, normally consist of relatively low cost, low carbon
steel susceptible to hydrogen embrittlement, hydrogen sulfide induced
corrosion, and chloride stress corrosion and cracking. While efforts have
been made in the past to overcome such problems, they have not met
with wide acceptance. For example; while the entire pipe, or pipe liners
may be formed from stainless steel, this is a far too costly solution.
Stainless steel liners have been proposed but it has been found that
hydrogen diffusing into the clearances between the liner and pipe bore
causes problems such as hydrogen embrittlement, and deformation of
the liner when the hydrogen expands.
Biro Technologies provides a more cost-efficient, more effective solution
for internal pipe coating, a new generation of Epoxy-Polyamidoamine
Zinc primer and Epoxy-Siloxane top coatings that are in every way
superior to the old coating products.

Executive Summary
Contamination of exposed structural surfaces with chemical or biological
material can occur in both civilian and military contexts. Contamination can
occur accidentally, such as during the conveyance of hazardous materials
from one site to another, or can occur on purpose, such as in chemical or
biological warfare. Such materials can remain for a significant period of time
on exposed surfaces such as equipment, vehicles, aircraft, buildings, etc.
Photocatalytic coating composition containing Epoxy-Siloxane polymer that
hold the photocatalyst in place without degrading the desired performance of
the coating.
The coating may be applied by conventional coating methods to organic or
inorganic structured surfaces where photocatalytic activity is desired.
The coating after dries leave an adherent, flexible, durable, and long-lasting
photocatalytic coating having a large surface area and exhibiting high surface
activity against pathogens and pollutants such as bacteria, viruses, mold,
fungi, and volatile organic compounds.
Photocatalytic coating the solution for self cleaning, self-decontaminating
and anti-bacterial application.

Executive Summary
Ice build up is a serious problem and major economic impact in the aircraft
industry.
Ice-phobic coatings could benefit the Aircraft Industry, NAVAIR and Air Force
for de-icing composite and aluminum wings and fuselages. With respect to
NAVAIR, aircraft de-icing is an important function at the many Navy facilities
that support aircraft operations. Because of the high cost of purchasing
deicing fluid, and the potential negative impact of glycol discharges on the
environment it is optimal to minimize the volume of propylene glycol or
ethylene glycol used in its aircraft de-icing operations.
Ice-phobic coating significantly outperforms other ice-phobic coatings,
providing measureable economic and environmental benefits.
Ice-phobic coating significantly reduces ice adhesion when applied on
aluminum surfaces compared to other commercially marketed ice-phobic
coatings
The ice-phobic coating could be applied as a very thin film to aircraft
surfaces without significantly increasing the weight.

Detailed Product Information
Epoxy-Siloxane Corrosion Protective Coating
For many years the conventional anti-corrosive paint systems for long
lifetimes has been to utilize zinc primers. The type of primer normally
specified has been zinc ethyl silicate.
The reason for using this type of technology giving zinc-zinc metal contact
and, consequently, excellent cathodic protection properties akin to those
obtained from galvanizing.
The new Epoxy-Polyamidoamine zinc primer and Epoxy-Siloxane finish coating
has many improvements comparing to the zinc ethyl silicate primer such as:
- Zero VOC
- Excellent adhesion
- Surface tolerant (surface preparation may be less than ideal)
- Much higher flexibility
- Long shelf life (2 years)
- Simple processing (no hydrolysis)
Typical uses of Epoxy-Polyamidoamine zinc primer and Epoxy-Siloxane finish
coating are to protect ferrous surfaces in aggressive atmospheres against
corrosion, such as: industrial and marine atmospheres (ship building, oil
drilling platforms, harbor installations) Chemical attack (internal coating of
tankers, containers, pipelines), bridges, structural steel etc.

Detailed Product Information
Epoxy-Siloxane Ice-Phobic coating
Ice at surfaces often cause serious safety risks and damage in technical
applications such as airplanes, ship decks, cables etc.
Epoxy-Siloxane ice-phobic coating with a low surface energy 18-21
dynes/cm2 inhibits ice formation and lowers the adhesion between ice and
the substrate surface.
Epoxy-Siloxane ice-phobic coating is characterized as a smooth anti adhesive
surface with local, regularly distributed ice nucleation points, which are
separated from each other. Small local ice nucleation sites with higher
surface energy are surrounded by anti adhesive ice repellent segments with
lower surface energy.
The adhesion of the generated ice crystals is reduced dramatically both in
strength and contact area. The removal of the generated ice crystals is
possible just with the flow of the brine along the surface.
The most desirable solution to the de-icing problem, would be to apply a
material that prevents ice from building up in the first place rather than
taking it off after the fact.

Epoxy-Siloxane Antifouling Coatings
•
•
The long-used “tributyl tin” anti-fouling compounds are now banned.
Epoxy-Siloxane Antifouling technology shows good long-term performance
by effectively shedding marine organisms regularly over a long service life.
Types of anti-fouling applications:
Nanostructured. Incorporating nanoparticles in the Epoxy-Siloxane
antifouling coating which remain permanently as part of the coating. Due
to their small size, nanoparticles will remain in the lattice of the coating
and cannot leach out but continuously release ions that provide long-term
anti-fouling performance.
Low friction. Epoxy-Siloxane antifouling release coating is cleaned by
sufficient movement through water. The low friction antifouling technology
minimizes the attachment of marine organisms to a ships hull due to the
low friction characteristics of the coating, which uses Epoxy-Siloxane
polymer.
This low-friction type antifouling coating is very eco-friendly, as it doesn’t
contain any biocides or potentially hazardous materials.

Detailed Product Information
Epoxy-Siloxane Photocatalytic Coatings
Epoxy-Siloxane Photocatalytic coating a novel and new application field, with
self-cleaning self-decontaminating and anti-bacterial properties.
The unique Epoxy Siloxane polymer with strong adhesion and transparency is
the best delivery system to hold the nano-sized photocatalysts in place
without degrading the delivery system.
The special composite structure of the coatings can help separation and
transportation of the photo carrier, therefore having a high level of
photocatalytic activity and a long lifespan. When waste water or polluted air
passes its surface, organic pollutants are degraded by photocatalysis so that it
is self-cleaning. This method is effective on all types of organic substances and
will degrade them into carbon dioxide and water. It is efficient, energy-saving
and has no secondary pollution.
Epoxy-Siloxane Photocatalytic coating also decomposes organic matter by
oxidation, specifically bacteria, viruses and germs. The inorganic anti-bacterial
nano particles kill bacteria and inhibit propagation of pathogens, molds and
epiphytes to prevent disease spread. It has a long term effect on killing
bacteria, no harm to human beings and no pollution on environments.

Detailed Product Information
Defense against graffiti
Epoxy-Siloxane coatings are relatively new and offer an extremely long-lived
surface from which graffiti, fly-posters and other soiling can be removed
easily and repeatedly, using safe and mild agents, without the loss of
properties, performance or appearance of the coating itself. This type of
coating has release properties similar to those of non-stick domestic
kitchenware. Any soiling can easily be removed using aqueous
surfactant/detergent mixtures, or at worst, benign chemical mixtures which
have no effect on the coating itself, resulting in a truly permanent anti-graffiti
coating.
Epoxy-Siloxane Coating offers an excellent defense against graffiti and is
easily cleaned without leaving a shadow after cleaning.

Detailed Product Information
Nuclear radiation
High energy neutron radiation is present in nuclear reactors, which can lead
to degradation processes in the materials of critical components.
Under the effect of neutron bombardment,the substances in Epoxy-Siloxane
coating are not converted into radionuclides and has no substances in the
matrix which would have an adverse effect on the reactor.
Epoxy-Siloxane Coating is essentially unaffected by nuclear radiation and has
an excellent rating for decontamination. The coating performed without any
defects on irradiation to a cumulative dose of 5500 megarad as tested.
Organic coating systems show considerably lower decontamination factors
with typical values of 500 to 1000.
