MUNICH -- At EUROCOAT 2005 in Lyon, France,
from September 27 to 29, the Munich-based WACKER Group will be presenting
novel organofunctional alpha-silanes for the coatings, adhesives and sealants
industries. The additives enhance the application properties of coating
materials and enable the formulation of scratch-resistant coating systems
that are harmless when used as intended.
WACKER has expanded its successful range of GENIOSIL® organofunctional
silanes. At EUROCOAT 2005, the chemical group will be presenting a new
generation of organofunctional a-silanes in which the classic propylene
bridge has been replaced by a methylene bridge. The result: the new silanes
are extremely reactive and facilitate much better hydrolysis and condensation
of the Si-alkoxy groups than standard-grade silanes.
This turbo effect can be exploited to produce completely novel fast-curing
adhesives and sealants. Paints and surface coatings, too, benefit from
the markedly improved coating properties conferred by WACKER's new GENIOSIL®
a-silanes. It all boils down to the crosslinking mechanism. Thus, automotive
finishes formulated with GENIOSIL® not only feature excellent curing
and improved adhesion. They also offer better hardness and scratch resistance
along with chemical resistance. Manufacturers of furniture coatings can
also use these innovative GENIOSIL® silanes to produce scratch-proof
coatings that are considered harmless when used as intended.
New Terpolymer from WACKER POLYMERS
At EUROCOAT, WACKER will also present a new generation of terpolymers
based on vinyl acetate, ethylene and methyl methacrylate. Developed exclusively
by WACKER POLYMERS, VINNAPAS® terpolymers combine the benefits of
polyvinyl alcohol-stabilized vinyl acetate/ethylene (VAc/E) copolymers
with the strengths of styrene acrylate or pure acrylate. Terpolymeric
VINNAPAS® binders are highly efficient and offer excellent mechanical
stability. They have a proven track record of enhancing the properties
of cementitious dry-mix mortars.
Self-leveling flooring compounds modified with the new terpolymers are
extremely wear resistant and display very good flow properties with all
plasticizing admixtures. Additionally, the terpolymeric binders impart
good tensile adhesive strength to cementitious tile adhesives, especially
for critical heat aging.
Silicone Resin Emulsion Paints Initiative Now Focusing on Eastern Europe
The "We Help Facades" silicone resin emulsion
paints (SREP) initiative launched by WACKER SILICONES in 2003 is firing
on all cylinders again this year. Having focused last year on France,
Spain and Portugal, the participating companies have now turned their
attention to Eastern Europe. Polish, Russian, Slovenian and Czech language
versions of the official website are currently being prepared. By year-end,
the website will be available in more than 15 languages.
Further WACKER Product Highlights at EUROCOAT 2005:
- SILRES® Silicone Resins Boost the Heat Resistance of Surface Coatings
SILRES® resins are specialty polysiloxanes that markedly enhance the
heat resistance of coatings and polymers. They serve as binders for high-temperature-resistant
paints and surface coatings. Preferred applications are automotive exhaust
systems, heat shields and aerospace engines, heat-resistant exterior paints
in the chemical industry, crude-oil extraction and refining, and the coating
of ovens, cookers, grills and baking trays.
- SILRES® BS: Silicone Resin Emulsion Paints for Effective Facade
SILRES® BS silicone resin emulsion paints (SREPs) rank among the latest
facade coating systems. The reason for their huge success is a good marriage
of the outstanding properties of mineral and synthetic-resin-bound paints.
This includes very high water-vapor permeability, very low water absorption
and extreme longevity. SILRES® BS products are innovative, environmentally-compatible
raw materials for the production of water-repellent masonry coatings,
construction chemicals and materials.
- Extention Insulation and Finish Systems with VINNAPAS® Redispersible
VINNAPAS® redispersible powders are high-quality binders for the modification
of systems based on cement and gypsum plaster. These are used in numerous
construction-industry applications to enhance tile adhesives, self-leveling
flooring compounds, mineral plasters, joint sealants, sealing slurries,
gypsum plasters, repair mortars, and powder paints. Increasingly, they
are also used as components for extension insulation and finish systems
(EIFS). Dry mortars modified with VINNAPAS® redispersible powder feature
excellent adhesion, cohesion, flexibility and flexural strength. Depending
on the type of powder, hydrophobic (i.e. water-repellent) property enhancement
is also possible when requested.
- VINNOL® Surface-Coating Resins: Versatile Binders for Industrial
Coatings and Printing Inks
VINNOL® is the WACKER brand name for a broad range of vinyl chloride
and vinyl acetate copolymers. The range contains grades both with and
without functional groups, and so offers a wide spectrum of uses. All
VINNOL® grades can be combined with each other, a fact which allows
the coating or printing ink to be customized to the requirements of the
application. VINNOL® E grades, which have excellent pigment wetting,
are suitable for formulating gravure and screen-printing inks, as well
as inkjet inks. The VINNOL® M grades, which contain carboxyl groups,
show outstanding adhesion to metal. Therefore, they are the binders of
choice for formulating printing inks and surface coatings for metal or
metallized substrates. Further applications of VINNOL® include plastic
coatings, wood varnishes and adhesives for PVC pipes.
PIOLOFORM® - Polyvinyl Butyrals for the Surface Coatings and Printing
PIOLOFORM® polyvinyl butyrals are versatile binders. They exhibit
excellent adhesion to aluminum foils and plastic films and are therefore
the preferred binders for formulating printing inks for flexible laminate
packaging. PIOLOFORM® polyvinyl butyrals are flexible, odorless and
tasteless and show low solvent retention. Formulations based on specialty
low-viscosity grades can absorb more pigments and thereby greatly increase
the intensity of the ink. PIOLOFORM® is also indispensable in a large
number of industrial coatings, such as corrosion-protection primers, masonry
paints and plastics paints.
- VINNAPAS® Solid Resins: Polyvinyl Acetate for Coatings and Adhesives
Due to their excellent adhesion to various substrates, such as wood, cardboard
and metal, VINNAPAS® solid resins are the preferred binders for solvent-based
adhesives in the adhesives industry. VINNAPAS® can also be used to
formulate primers for metallizing packaging or modifying NC coatings.
The product range covers homopolymers and copolymers in various viscosities
and delivery forms.
- HDK® Pyrogenic Silicas - Flow Behavior of Liquid and Powder-Form
Coating Materials Always Under Control
Pyrogenic silicas from WACKER (brand name: HDK® pyrogenic silicas)
are ideal for thickening, controlling powder flow and reinforcing coating
materials, printing inks, composites and adhesives, as well as many other
applications. In the formulation of low-solvent coatings (high solids),
such as for automotive coatings and solventless and water-based systems,
HDK® pyrogenic silicas offer selective control over coating thickness
and leveling. Moreover, HDK® pyrogenic silicas improve the storage
stability of the systems by effectively preventing pigment and filler
sedimentation. In clear coats, HDK® pyrogenic silicas make for high
