GARAMITE

Our brands
for PVC
applications

These powdered rheology additives are
based on organophilic phyllosilicates.
They generate a pseudoplastic flow
behavior in PVC plastisols.

RHEOBYKThese organic rheology additives generatea thixotropic flow behavior, optimizing therheological properties of PVC plastisols.

VISCOBYKOur portfolio for PVC applications comprises fivebrands and includes solvent- and water-based
additives. Suited to individual applications, we alsooffer low emission, eco-friendly products.

This product family facilitates the processabilityof PVC plastisols. It reduces the plastisol’s
viscosity and is suited for applications withmedium to high shear rates.

DISPERBYK/DISPERPLAST
We developed these additives to optimize theincorporation of solid particles into liquid and solidmedia. In particular, they support extremely
sophisticated PVC applications.

BYK
This brand combines a broad portfolio of wetting anddispersing additives, defoamers, air release agents,
wax additives, and processing additives. They optimize
the product properties of PVC plastisols and support
their processability.

Our additives:
added value for a unique material
Characterized by excellent durability, diversity, and longevity, PVC is oneof the most popular materials worldwide. To achieve an excellent end
product quality, it is crucial to include additives during production.
They constitute the product’s functionality as well as its mechanical andesthetic properties. Moreover, additives facilitate production processes.
As a globally leading producer, we provide a broad additive
portfolio for a wide variety of PVC applications. Formulatorsand compounders, system providers as well as end users
rely on our additives, well aware of the fact that they canalso reckon with our services and our unique know-how,too. This is true for producers of floorings, wall coverings,
technical textiles and many more PVC applications.

Thanks to our close collaborations with direct andindirect customers along the value chain, we broaden ourapplication know-how continually. Our comprehensive
understanding of the markets we serve puts us in a position
to anticipate new trends and develop innovative applications
for future challenges, creating added value for customers,
end users, and consumers alike.

Ideal for floorings, leather,wall coverings, and printing inks
Our additives provide different functions. They optimize the rheology
and flow behavior of PVC plastisols and control air release. Others
help incorporate fillers and pigments. In printing inks and coatings,
they can be employed to create product-specific properties.
Selecting the suitable additive depends on many factors.
The interaction of materials and production conditions plays
a major a role in this context. If desired, we support ourcustomers with extensive tests to analyze the behavior of
our additives under their production conditions. In doing
so, we not only help to produce an optimal product,
we support efficient and reliable production processes, too.
Our additives optimize the production of the following
applications.

Floorings

Natural leather and coated fabrics

With our wetting and dispersing additives, viscosity reducers,
and foam stabilizers, we meet a number of challenges
arising during the production of roll materials as well as
carpet and luxury vinyl tiles (LVT). The wetting anddispersing additive BYK-1165, for example, is designed
to incorporate fillers into highly filled plastisols with low tomedium shear rates. DISPERPLAST, on the other hand,facilitates the incorporation of fillers into thermoplastic
PVC compounds.Both products also optimize the flow
behavior of the materials. For anti-static applications,
we recommend BYK-5128.

Natural leather and coated fabrics are used in many consumer
products. These range from car seats to furniture andinclude shoes, bags, clothing, and accessories. Our additives
support the production and finishing of natural leather andcoated fabrics based on PVC or polyurethane (PU).

By reducing viscosity, our VISCOBYK additives support
the plastisol’s processability. In particular, this applies tomaterials with few or no fillers. For indoor applications,
VISCOBYK-5120 und VISCOBYK-5125 have provenextremely successful, as they show few emissions thanks
to their low volatility. BYK-8020 and BYK-8070 help tostabilize mechanical foams, one is based on silicone,
the other on soap.

Depending on the applications, our customers can choose
between solvent- and water-based additives. Our surface
additives help optimize the quality and feel of the materials.
Our wax additives create shine, smoothness, grip, andcomfort. Our wetting and dispersing additives serve toincorporate pigments and fillers into the finishing.
To optimize different processing parameters during theproduction of the finishing, our defoamers, rheology andprocessing additives are first choice. Defoamers destroy
unwanted foam bubbles, generating flawless surfaces.
Rheology products better the flow behavior, and processing
additives improve the release properties as well as the cellstructures of the PVC plastisols.

Technical textiles
Coated technical textiles need to fulfill a number ofrequirements regarding safety, comfort, and opticalproperties. Our wetting and dispersing additives help
stabilize the pigments in the relevant PVC plastisols.
RHEOBYK and GARAMITE additives serve to precisely
control the flow behavior of the pastes during processing.
Our defoamers, e.g. BYK-3155, prevent air pockets
which could impair surface properties.

Wall coverings
These days, wallpapers have to fulfill the highest esthetic
expectations while keeping production as efficient as possible.
Given these factors, PVC plastisols used in wallpaper
printing need to fulfill one decisive requirement: Theirprocessing should not impair the product’s esthetic quality.
Consequently, the following viscosity reducers are suited for
optimal processing: BYK-1166 is suitable for PVC plastisolswith high yield value. It is designed for products with low
to medium shear rates. Moreover, it is characterised by its
positive effects on surfaces and its degree of whiteness.
The VISCOBYK-5000 additives are specifically designedfor low emission formulations.
To incorporate pigments, we recommend our wetting
and dispersing additives, e.g. DISPERPLAST-1150 orDISPERBYK-2157.

Printing inks and color masterbatches
for PVC applications
Intense colors plus excellent processability characterize
the quality of printing inks and color masterbatches.
Both properties can be achieved with our additives.
To incorporate pigments, we recommend our solvent-freewetting and dispersing additives, e.g. DISPERPLAST-1150
or BYK-9076. These low emission additives moreover help
to optimize the ink’s processability.

PVC dry blends and masterbatches
Given their diversity and their economic efficiency, PVC dry
blends and compounds are becoming increasingly popular.
We designed DISPERPLAST-1180 specifically for thosethermoplastic applications, in which standard dispersing
additives find their limits.
Allowing a higher filler volume as well as a homogenous
distribution of particles, DISPERPLAST-1180 can be employedin the production of luxury vinyl tiles (LVT). It has positiveeffects on the plastification process and on the material’s
melting properties. Besides, the processing additive
BYK-P 4100 supports release properties, improving
production efficiency as a result.
