BASF Performance Minerals Enhance Coatings and Inks
Performance minerals solutions from BASF can deliver
• Increased profitability
• Improved processing efficiency
• Improved performance and appearance
• Controlled rheology
BASF's broad line of performance minerals are produced in state-of-the
art processing facilities, where service and quality are key components
of every product offering. We also provide technical and logistics sup-
port, as well as product development collaboration.
In addition to being the
world's leading chemical
company, BASF is also a
world-leader in surface
and materials science
and a foremost supplier
of high-value perform-
ance materials for more
than a century.
Kaolin
Kaolin is most commonly associated with
titanium dioxide extension; However, it is
engineered to perform as a multifunctional
extender that simultaneously addresses a
wide variety of formulation needs.
BASF kaolins in coatings applications can
provide:
• Formulating flexibility
• Titanium dioxide extension
• Increased opacity and tint strength
• Sheen control
• Stain resistance
• Improved holdout
• Brushing ease
• Mud-crack resistance
• Color pigment extension
• Pigment suspension
• Rheology control
• Low VOC capabilities
Architectural Coatings
High brightness, ease of dispersion, controlled
particle size distribution, low specific gravity
and platy morphology make kaolin a value-
added component in flat, eggshell, semi-gloss
and high-gloss paints.
Interior Flat Paints
In water-borne and solvent-borne interior
paints, kaolin adds value by providing titanium
dioxide extension (ASP® 170 , ASP NC)
improved opacity and tint strength (Ultrex®
96 and Satintone® products), sheen control
(Mattex® and Mattex MX), color pigment
extension (ASP 170), washability and stain
resistance (ASP NC) and scrub resistance
(Satintone W).
Exterior Paints
In water-borne and solvent-borne exterior
paints, kaolin positively impacts tint reten-
tion (ASP 400 and Satintone W), gloss
retention (ASP 170) and one-coat coverage
(ASP 170). The platy structure and low oil
absorption of ASP 400 provides a low
degree of chalking, crack resistance and a
high resistance to dirt pick up.
Gloss and Semi-Gloss Paints
In water-borne and solvent-borne gloss and
semi-gloss paints, ultrafine particle size kaolin
products provide excellent titanium dioxide
extension while maintaining high gloss. ASP
G90, ASP 200 and ASP 170 kaolins can be
used in both latex and solvent-borne paints
to improve coverage at both high and low
PVC's. ASP G92 and ASP 072 products are
recommended for water-borne paints only.
Performance Minerals Solutions for Architectural Coatings
Automotive Coatings
Kaolin plays an important role in automotive electro-deposition primers by providing tank stability, film smoothness, corrosion resistance,edge film build and uniformity. BASF kaolinproducts for automotive primers are character-ized by low salts content, easy dispersion, goodthrowing power and proven performance.
Polyester Gel Coats
Kaolin improves blister resistance in unsaturatedpolyester gel coats, which protects fiberglasscomposites in products at risk of attack by water,such as boats and bathtubs. Translink® 37 surface-treated kaolin provides improved blisterresistance, better color retention, and viscosityand sag control compared to calcium carbonate,talc and synthetic silica. Satintone 5HB calcinedkaolin provides improved opacity. Studies indi-cate that kaolin also reduces gloss reduction better than other minerals additives after long-term exposure to water.
Industrial and Specialty Coatings
Kaolins are broadly used in industrial and specialty coatings:
• Traffic Paint - Satintone W kaolin offers titanium dioxide extension and abrasionresistance.
• Textured Paint - ASP 900/902 kaolins offerslow viscosity, leveling and brushing ease.
• Baking Enamels - ASP RO kaolin offersimproved adhesion, titanium dioxide exten-sion and excellent film properties.
• Coil Coatings - ASP 200 and ASP 170kaolins offer improved adhesion and titaniumdioxide extension.
Performance Minerals Solutions forAutomotive and Industrial Coatings
Hydrous kaolins are common components ofmost ink systems. Kaolin extenders for ink appli-cations are characterized by high whiteness anda tightly controlled fine particle size distribution.Hydrous kaolin is pulverized and surface treatedfor ease of dispersion, improved hydrophobicity,improved wetting and rheological control. Kaolinis a versatile ink extender that simultaneouslyaddresses a wide variety of formulation needs.
Kaolin used in ink applications can provide:
• Strike-through resistance
• Color pigment extension
• Low abrasion
• Rheology control
• Fast dry time
Offset Inks
Offset inks are applied in thin films that contain avery high concentration of pigments. Both weband sheet fed offset inks run at high speed andrequire high viscosity and tack, as well as a highresistance to emulsification from the fountainsolution. ASP 101, ASP RO and ASP 170 prod-ucts offer the best balance of properties andemulsification resistance in ink fountain solution.ASP G90 hydrous kaolin is especially suited foroptimal colorant spacing for improved opticalproperties as well as promoting high print gloss.
Gravure Inks
Compared to offset applications, gravure inkscan use more kaolin extender in the formulation.The very low abrasion and platy nature ofhydrous kaolin makes it an ideal product forgravure inks. ASP 600 kaolin provides excellentstrike-through resistance and low abrasion prop-erties and is a very good choice for gravure inks.Other grades suitable for this application are ASP200, Buca and Catalpo hydrous products.
Performance Minerals Solutions for Inks
ASP 602 kaolin, a spray-dried product is alsosuitable for this application where high shearcapabilities are available for dispersion.
Flexographic Inks
The quantities and types of kaolin extenders thatare added to flexographic inks are similar tothose used for gravure inks. For solvent-borneapplications, such as flexible packaging, the highdegree of whiteness and light scattering and fineparticle size of ASP 170 and Ultrex 96 kaolins arenecessary to efficiently extend TiO2, provideopacity and promote optimal spacing of colorantparticles. For water-borne applications, ASP 170and Satintone 5HB products provide excellentpigment extension, hiding and ease of dispersion.
Screen Inks
Screen inks are characterized by high viscosity toallow for a high film thickness. Compared togravure and flexographic applications, a thick filmis applied during screen printing to providevibrant color, opacity and longer service life.Calcined kaolin extenders provide high whitenessand light scattering. Satintone 5HB calcinedkaolin is an excellent kaolin extender for screeninks.
Specialty Inks
Kaolin extenders are also used in several types ofspecialty inks, including letterpress, security,ultraviolet curing and electron beam curing. Fortechnical advice in using kaolin extenders in anyof these applications, please contact your BASFrepresentative.
